Difference Between Eccrine and Apocrine Glands – What You Need To Know

Last updated on November 8th, 2018 at 04:41 am

difference between eccrine and apocrine glands

Difference Between Eccrine and Apocrine Glands – What You Need To Know

When someone deals with abnormal or excessive sweating, he will most likely come across the two types of sweat glands that are causing us to sweat.  Because there are different reasons why people sweat, it is important to understand which sweat glands cause what kind of sweating.

In this article, I am going to talk to you about the difference between eccrine and apocrine glands, which are the sweat glands that are located all over our body.  I am also going to share what to do about your sweating.

Why Do We Sweat?

First of all, it is important to understand why we sweat.

Sweating is a natural process in our body that helps us to reduce and deal with all kinds of stress.  For example, when the temperature of our body rises, our heart rate increases, which puts the body under stress.  Our body knows that if the temperature continues to rise, it could lead to many things, including a heat stroke.  Therefore, our brain is alarmed and looking for solutions.

The sweat glands are the ones that can help cool the body down.  Whenever the temperature of our body up, our brain quickly signals the sweat glands to quickly produce sweat.  Sweat evaporates through the pores of our skin and each sweat drop takes along a little heat, which quickly helps the body to maintain the temperature.

Sweating is, before anything else, the cooling system of our body!  But that is not all.

When we are in great fear, in lots of pain, and suffering from depression, for example, our bodies are under great stress.  And stress hormones are released into the bloodstream, which also makes our heart race, and our brain goes nuts.  We also sweat under these circumstances because our sweat glands are triggered by the nervous system, by which our body can help to keep those nerves under control.

By nature, when we are nervous or in a panic attack, our body temperature quickly rises and in no time all our sweat glands are heavily busy to maintain the temperature, but also release that stress that is trying to build up in our body.

Therefore, sweating is a very important body function that not only maintains our body temperature but also helps our nervous system to become calm again.

The Eccrine and Apocrine Sweat Glands

We have two types of sweat glands in our body which serve different purposes.

In this next table, I am going to describe each one of them, where they are located, each of their functions, among other important things about them.

Eccrine Sweat Glands

Apocrine Sweat Glands

On what parts of the body are they?

These are found all over the body, with higher concentrations in hands and feet.  It is known that you will have around 300/cm². We humans have the highest concentration of these sweat glands compared to animals.


The sweat glands are only found in a few parts of the human body: In our armpits, in the ear, in the areola of the breast, in the external genital area, and in the eyelids.

There are not nearly as many apocrine sweat glands per cm² as there are eccrine sweat glands.  These glands concentrate more in places where many hair follicles are found, which I explain in another answer.

Where are they located?

They are located in the dermis, which is close to the surface of the skin. These sweat glands are located deep underneath the skin.

What is the primary function of them?

The eccrine sweat glands are responsible for temperature reduction in our bodies.  When our body temperature goes over the regular 98.6 Fahrenheit degrees, our brain signals these sweat glands to produce sweat.  Sweat evaporates and takes a little of the heat along with each drop.

The eccrine sweat glands also carry stored toxins away.  It is a way of helping the kidneys and liver reduce excess toxins.

And there is another great function, it unclogs the pores from all the chemicals that you put daily onto your skin.

There are modified versions or the so-called sister glands of the apocrine sweat glands.  For example, in the areola of the breast, breastmilk is produce and in our ears, earwax is produced.  However, in the other body parts, a fatty liquid is excreted because of emotional and psychological factors.

Its function is to reduce stressing factors, because our body needs to release that energy produced by stress somewhere, and one way this can be done is sweating through the apocrine sweat glands.

Sweat comes out periodically and happens not just because of emotional induction.  Sweat from the apocrine sweat glands attracts the opposite sex, as much as in humans as in animals.

What is the secretion made of?

Sweat from these glands consists of water, although small quantities of sodium chloride (salts) come along. Sweat produced in the apocrine sweat glands is a fatty substance (earwax, breast milk, for example).  It is mostly made of sialic acid.

Sweat itself is odorless, yet sweating stinks when bacteria that live there, feasts on this protein-loaded sweat and breaks it down.

How does the sweat come out?

This watery fluid is pushed directly through the pores onto the skin.  The secretory part of these glands is really small when compared to the apocrine sweat glands. Since these sweat glands are located deep underneath the skin, they push out there sweat through a duct into the hair follicles and which then contract until the sweat comes out.

These sweat glands are large compared to the eccrine sweat glands and their secretory part is also large.

Who has these glands?

Eccrine sweat glands are fully developed when an infant is born, which is why small babies can sweat the first day after being born.

Everybody has sweat glands, but in some cases, these are not active (a condition called hypohidrosis).  As you age, your sweat glands become less and less active.

These sweat glands are all over the body when an infant is born.  However, they change over time and will eventually only be in the above-mentioned body parts.

These glands are not active until the onset of puberty, which explains why teenagers start to smell so bad when they reach that phase.  These sweat glands also become less active as you age.

What are they good for?

Eccrine sweat glands regulate the temperature of our body.  If we could not sweat, we would be prone to heat strokes and other health issues.

Therefore, sweating is not only beneficial, but necessary for our whole body, but especially for our skin.

Sweating a lot means that bacteria and viruses on our skin are washed away in a timely manner before they can enter our body. Sweating is really an antibody.

Unlike the eccrine sweat glands, these glands do not regulate or control body temperature. They release tension that is produced by emotional stress or psychological factors.

Because the modified versions of these sweat glands produce earwax, our ears are being protected and oiled all the time.  And in breastfeeding moms, these sweat glands are responsible for a rich milk that feeds the baby.

However, that is not all, these sweat glands contain a substance that attracts the opposite sex.  Although not perceivable, our brain immediately senses it.  Therefore, sweat from these sweat glands stimulates the opposite sex.

That explains why people find each other attractive and hot even when they are sweaty.

When are these glands active?

Since these sweat glands are responsible for temperature regulation, they get active only when our body temperature is raised.  This can happen through induced sweating like fitness routines, working physically, being in the heat, relaxing in saunas, and others.

However, they can also become active when emotionally or psychologically induced through anxiety, panic attacks, fear, sexual stimulation, among others.

The latter ones are because most of them make our vital body organs being stressed, which produces heat in our bodies.  Emotional induction seems to affect our palms and feet more than other body parts.

These sweat glands are active periodically, as stated above.  But the more emotions, the more sweat is going to be pushed out. People that get nervous tend to sweat a lot in their armpits.  Also, people suffering from depression and anxiety also tend to have very active apocrine sweat glands.

How much sweat do they produce?

Both sweat glands produce as much sweat as much needed.  The more these sweat glands are triggered, the more they will produce.  For example, the apocrine sweat glands will produce an awful lot of more sweat when a person is sexually stimulated.  And the person in the gym doing a rigorous exercise routine will also produce more sweat.

There is, however, a rare disorder in the sweat glands known as hyperhidrosis, a condition in which a person sweats more than 4 times the necessary amount.

Primary hyperhidrosis is when the sweat glands just do not know how much sweat to produce and there is no real reason behind it.  Also, not a cure is found for this disorder.  Around 2% of the population suffers from this condition.

However, secondary hyperhidrosis is when a person sweats excessively, but for a known reason.  There are many reasons for a person to sweat excessively, namely heart disease, Parkinson’s disease, obesity, pregnancy, and others.  It can also be induced by the foods that you consume (spicy foods trigger excessive sweating, etc.)

Can I Stop Sweating?

As you can see, sweating is not only necessary, it is good for your body!  Sweating in normal quantities is also not embarrassing or annoying.  However, things are different when you suffer from hyperhidrosis.  In many cases, there is nothing you can do about it while you can find a solution in other cases.  When you sweat excessively the worst thing is the embarrassment it causes.

You are living, depending on what type of hyperhidrosis you have, in constant embarrassment.  I mean, who likes to sweat all over the body when sitting in the living room?  Who wants to have completely wet palms when going to a social gathering?  Nobody!  But that is what happens when people suffer from primary or secondary hyperhidrosis.

If you suffer from secondary hyperhidrosis, you can (in many cases) find the cause and a cure for it.  For instance, you can try to lose weight, if your excess weight is causing you to sweat more than necessary.  When you are pregnant, you know it will go over as soon as your baby is born.  If one of the side effects of cancer is excessive sweating, you know that it will stop if you beat cancer.  The list could go on.

However, when you suffer from primary hyperhidrosis, things are quite different.  Excessive sweating for no reason can be highly annoying.  Running around with sweaty palms or huge sweat marks in your pits is not particularly attractive.  You feel embarrassed all the time because you cannot be yourself.

Since there is nothing you can do about the condition, you need to find other solutions to reduce the emotional side effects that this causes.

My Story and Solutions

I have lived with primary hyperhidrosis ever since the onset of puberty and it is not cool.  You can read about my story here.  The good thing is that after years and years of searching for an answer, and even accepting the fact that I was confined to live with this condition for the rest of my life, I found the solution.

Every single day I use the Thompson Tee sweat proof undershirt because it soaks up all the sweat produced in my armpits before it can reach the outer layer of clothes.  Although I do not sweat less by using this shirt, I can prevent the embarrassing sweat marks that come with excessive sweating in your pits.  Also, I do not have to worry about what kind of clothes I wear, neither do I have to worry about having them spoiled in no time.

Although the Thompson Tee is a great solution to my primary hyperhidrosis, I also periodically use Sweatblock.  This is a clinical strength antiperspirant which I apply into my armpits to block the apocrine and eccrine sweat glands temporarily but completely.  I have been able to stop sweating for 7 days with just one application of Sweatblock.

Both of these products are absolute life-savers as they have given me back the confidence that I had been lacking for so many years.

If you are interested to read more about the mentioned products, please read the complete product review of Sweatblock here, and the complete review of the Thompson Tee undershirt here.

Bottom Line

We do sweat for a reason and it is good that we sweat because we would face quite a few health issues if we didn’t have the amazing sweat glands.

Summarizing, we learned that the eccrine sweat glands are primarily for temperature maintenance, while the apocrine glands help our body to deal with stress factors, and the modified versions feed babies and keep our ears healthy.  Both have different functions, and they are both important for our bodies.


That is it for now.  I hope you learned something new today.  Did you know the difference between eccrine and apocrine glands?  If so, of which difference were you aware of and which ones not?  Please leave me a comment, question, experience, or opinion below.

Generalized Hyperhidrosis Causes – What Makes You Sweating Excessively?

generalized hyperhidrosis causes

Hi everyone,

did you know that some people sweat excessively but for a known reason?  In this post, I am going to discuss some interesting facts about the causes of general hyperhidrosis, also known as secondary hyperhidrosis.

There are many people around the globe that sweat excessively.  Some of them do not even think of it as an indicator of a condition that is medically known.  In fact, I was one of them for years.  I knew that I was sweating more than other people and found myself very often looking at other people’s armpits to see if anyone sweat as much as I did.

However, it never dawned on me that I had a condition called hyperhidrosis.  Something that wasn’t causing any discomfort, just lots of embarrassment.  It was many years later that I found out that I suffer from primary hyperhidrosis.

But today, I am not going to describe primary hyperhidrosis, I am going to talk about generalized hyperhidrosis causes, treatments and solutions.

Why Do We Sweat?

Most of the people on this planet sweat, some sweat a little and others sweat a lot.  However, most of us do sweat for a good reason.

Our body has two types of sweat glands, of which the eccrine sweat glands are our body’s air conditioning system.  When our body temperature goes up, our brain signals de eccrine sweat glands, which are all over our body, to produce sweat.  With each drop of sweat from the eccrine sweat glands, a little heat is evaporated.  After a short time, our body is cooled down again and kept at a correct temperature.  This sweat is almost only water; therefore it does not smell bad.

The apocrine sweat glands, in contrast, are triggered by adrenaline.  Whenever we get excited, anxious, nervous, panicky, or stimulated, our brain signals the apocrine glands to produce sweat.  These sweat glands are located in our armpits, forehead, groin, palms, and feet.  This sweat is a thicker fluid and contains lots of proteins and fats.  Because of the contents of sweat from the apocrine glands, bacteria feasts on it and the breakdown causes the unpleasant odors.

So, on one hand, we sweat because we need to control our body temperatures, and on the other hand, we need to sweat so we can discharge energy produced by adrenaline.

What is Hyperhidrosis?

Now that we have the idea why we sweat, we need to look at the term hyperhidrosis itself.

As said, almost everybody sweats.  Small babies start sweating from the day they are born.  Since their sweat glands are not fully developed, they can sweat a lot in the first weeks of life.

In fact, the eccrine sweat glands are the only ones active during childhood.  At the onset of puberty, the apocrine sweat glands will start to kick in.  That is why children do not need to wear deodorant because they do not have the unpleasant odors that teenagers and adults have when sweating.

Hyperhidrosis is the term used to describe excessive sweating.  There are people, like me, that sweat more than we need to sweat.  A person suffering from hyperhidrosis can sweat at least 4 times the needed sweating per day.

The interesting thing though is that when somebody is suffering from hyperhidrosis, it does not mean that he will sweat excessively only during workout routines.  Individuals suffering from hyperhidrosis sweat literally all the time, no matter what activity they are doing.

What Is Generalized Hyperhidrosis?

There are two types of hyperhidrosis, namely, primary and secondary hyperhidrosis (the latter one is also referred to as generalized hyperhidrosis).

While people suffering from primary hyperhidrosis sweat for no obvious reasons, people suffering generalized hyperhidrosis, do have a reason behind their sweating.

Also, when you suffer from primary hyperhidrosis, you live it from the onset of puberty until you die, while generalized hyperhidrosis can affect you for any given time at any given age.

Let’s look into common causes for generalized hyperhidrosis.

Generalized hyperhidrosis: 10+ Causes

There are a number of things that can cause generalized hyperhidrosis, but they all have one in thing in common: You sweat excessively because of an underlying health issue.

Yes, you heard me right, if you have started sweating excessively only lately, and you are not a teenager or in your early adulthood, it can be a strong indicator of things that are different in your body from what they were.

Let me describe some common causes for generalized hyperhidrosis.

Disclaimer: The information presented in the following paragraphs contains general information about medical conditions and treatments.  It is not intended as advice, and should not be treated as such.  You must not rely on the information on this article as an alternative to medical advice from your doctor or other professional healthcare providers.  If you have any specific questions about any medical matter you should consult your doctor or other professional healthcare providers.  If you think you may be suffering from any medical condition you should seek immediate medical attention.  You should never delay seeking medical advice, disregard medical advice, or discontinue medical treatment because of information on this website.

It is important to understand that generalized hyperhidrosis affects your whole body.  When you have one of these medical conditions, your eccrine sweat glands are usually the more active ones, which is different when you suffer from primary hyperhidrosis.  Only the apocrine sweat glands are excessively active when having primary hyperhidrosis.

1) Ovulation, Pregnancy, And Menopause

While this is considered among the generalized hyperhidrosis causes, it is not a medical condition that requires immediate attention.

However, women tend to sweat more when they are ovulating.  The body temperature goes up when the egg is released from the ovaries, which is why women tend to have a slightly higher body temperature, which can result in extra sweating.

Sweating during the fertile days is probably not noticeable for many women, but some will see a difference in their sweating every month.

Pregnancy is a different story.  Your vital organs have to work “double” to support the new life in the womb.  Obviously, your heart rate will increase to pump the blood around the body and into your uterus to feed the baby and get all the necessary nutrients there.  That triggers the brain to signal the sweat glands to produce sweat in order to reduce your body temperature.

Especially in the last 3 months of pregnancy women tend to sweat more than usual.  I remember when my wife was pregnant with our first baby.  Since I suffer from primary hyperhidrosis, I sweat so much and used to tend my clothes all over the place so they could dry and then go into the laundry.

It ever frustrated my wife, because she didn’t like all the clothes hanging around.  When she was around seven months into the pregnancy, she told me that now she understood why I didn’t want my wet clothes directly in the laundry.  She did sweat a lot more during pregnancy.  I think she got a little idea what it is to sweat excessively.

As the baby grows in the womb, the load gets heavier and the harder a women’s body has to work to supply the baby’s needs.

And lastly, when a woman nears the menopause, she tends to sweat an awful lot more than she is used to.  Although it is not a condition worth getting medical advice, the added stress and hormonal change that this represents to a woman, sweating can severely affect her self-image.

Even though these causes are positive to some degree, you know that they will go away once the underlying issue is gone. You can live with the hope to not have to sweat your whole life, as I do.

The only advice that I give you when sweating excessively during these phases in your life, especially pregnancy is to stay hydrated.  Drink plenty of water and avoid the hot burning sun for extended periods.  Avoid radical temperature changes as much as possible to protect your baby and yourself.

2) Heart Diseases

This is a no-brainer and among the most common causes of secondary hyperhidrosis.  When you have heart disease you can expect to sweat a lot as a symptom.

I have often seen individuals suffering from any heart disease how they sweat an awful lot, which makes things more uncomfortable than they already are.

The apocrine glands become active because the body is under stress.  Your heart has a hard time doing what it is supposed to do and it sends out signals to the brain that it is running out of energy, which is when your adrenaline kicks in, causing the apocrine glands to sweat.

Also, since your heart is doing the best it can to get the blood supply to all your blood vessels and carry nutrients to each and every cell, your body temperature will naturally increase, causing the eccrine glands to produce an extra amount of sweat.

There are, however, some interesting facts about this issue.  Studies have found that generalized hyperhidrosis causes unpredictable sweating.  Patients with heart disease tend to develop strange sweating patterns that are a sign of more serious problems.

For example, you might start to sweat only in your right or left armpit, or just the right or left side of your body.  It gets even stranger because patients can sweat across the left and right side of the body, for example, sweat on the right side of your face, but in your left armpit.

Excessive sweating due to heart disease requires medical attention as soon as possible.  Some people might have had heart disease for some time without knowing it.  If these individuals have started seeing strange sweating in the recent weeks, it is a good sign that a doctors appointment should be very soon.

Some reports suggest that excessive sweating can be a sign of a heart attack.

I suggest that if excessive sweating has set in recently and you are older than 22, or you if have a child that is younger than 12, please do not wait to seek immediate attention.  The ones that are in between that age range can have primary hyperhidrosis, which should be ruled out first by a doctor.

3) Fever

Fever is another type one of the generalized hyperhidrosis causes.  When our body temperature rises above the desired 98.6 degrees Fahrenheit, our eccrine sweat glands are immediately triggered to produce sweat to take the heat out of the body.

A fever occurs when our body is trying to get rid of bacteria or virus.  Fever is a natural mechanism to kill harmful bacteria and virus by heating the body.  When the infections are taking over and our antibodies cannot deal with them anymore, our brain is triggered to send signals all over to produce heat and wipe harmful bacteria or virus out.

This natural mechanism produces sweating!  Although sweating because of a fever is not always necessary to treat, it is always good to observe how things progress.  If things do not change, there might be an infection that needs to be treated with antibiotics or other medications.

Therefore, if you or any of your family members get a fever, do not try to lower the fever.  Instead, make sure that it does not go too high, but let the body do its job in fighting harmful bacteria and virus.  And if sweating happens because of that, know that it is another natural mechanism to keep the temperature within the normal range.

4) Anxiety Disorders; Depression

As I said before, our apocrine sweat glands respond to stress.  Panic, anxiety, fear, and other disorders in a person triggers the apocrine glands.

That is why people who suffer from behavioral disorders tend to have excessive sweating phases.  The intensity of the disorder at any given moment will rule the intensity of sweating.

Why is that secondary hyperhidrosis?  You might think that this is something an individual should be able to have control over.  Whoever has had anxiety or depression, or has lived with someone that had it, will know that you are not in charge of your emotions when going through something that difficult.

There is absolutely nothing you can do in those moments; thus you need to seek help.  Be it clinical depression, or whatever type of behavioral disorder, you need to seek help to get out of the “dark pit”, as I like to call it.

Once you get help and excessive sweating goes away, you will know that you did the right thing.  There is no use in using antiperspirants or to clutch at any straw to keep symptoms away.  Go to the root of the problem, and symptoms will go away.

5) Obesity

In the modern western world, there is an abundance of food, but not only food, but there is also an abundance of unhealthy food.  Sugar and flours have taken over and you can not find many products today that are natural, organic, and healthy.

For instance, walk into the nearest convenience store and go through all the labels on the products.  You will be amazed at what you are buying daily!  When I realized that, I became completely nostalgic.

I had to learn that most of the things on the shelves today are highly addicting, which is why we overeat and naturally we will gain weight.

There are a few restaurants that have healthy options when it comes to delicious food.  Of course, most of them hide the real ingredients because the food industry has complete control, and sadly, politics participate in the fake campaigns for healthy eating.

Here is a quick example: Why would research centers worldwide offer recipes on their website that have beef as the primary ingredient?  It is common sense that beef is not healthy for individuals suffering from diabetes.

Anyway, I got carried away by the frustration this causes me.  Back to the topic: Skyrocketing obesity rates in our modern western world also increase generalized hyperhidrosis rates.  Obesity makes us prone to far more problems and diseases than probably any other thing.

Because people that are obese have more fat rolls, more heat is generated and they sweat more.

I was obese for the past 15 years of my life.  Measuring 6’6″, I weight around 290 pounds.  Sometimes I thought that losing weight would stop my sweating problem.  Nevertheless, it didn’t.  After losing around 50 pounds, there was no difference in my sweating, which means I am suffering from primary hyperhidrosis.

I don’t know about you, but if you started sweating excessively after gaining too much weight, try losing weight, and see if you can get back to normal.  If I would have a chance to not sweat excessively, I would take it.  Too bad it is not working on me.

6) Diabetes

I mentioned diabetes in the previous section.  People suffering from diabetes tend to sweat excessively as well.

It is the same problem that I have explained a few times in this article.  Your body is working overtime when having certain diseases like diabetes.

This hard work causes the body to generate heat, which again causes sweating.

Of course, diabetes is another issue that needs medical attention and advice.  If you can get your diabetes under control, or become free of it, your sweating should cease.

7) Hyperthyroidism

Another very common problem that is among generalized hyperhidrosis causes is hyperthyroidism.  Hyperthyroidism means that your thyroid glands are overboard with producing thyroxine.  This can have many symptoms like an unexpected loss of weight, increase of heart rate, and of course secondary hyperhidrosis.

Hyperthyroidism is a hormonal imbalance that affects your whole body, but sadly, it is often not found.  The problem with our thyroids is that they can mimic other health problems and you have a hard time to find out what the real problem is.  For example, an increased heart rate could point to heart disease, but it is the thyroid glands that causes it.

The overactive thyroid glands can make excessive sweating look like primary hyperhidrosis when it really is among the generalized hyperhidrosis causes.

Especially if excessive sweating has set on later in your life, but there is no apparent problem, it would be helpful to check if your thyroid is working properly.

The problem is normally treatable with medication or by complete removal of the glands.

8) Medications

Although only around 1% of patients that use medication that causes excessive sweating, it can cause discomfort and embarrassment for those.

There is a series of medications and drugs that can cause individuals to sweat excessively when using them.

The most common medications that can have excessive sweating as a side effect are the following (this list is not exclusive):

  • Pain relievers
  • Antidepressants (neuropsychiatric)
  • Some antibiotics and antivirals
  • Medications for heart disease
  • Chemotherapeutics
  • Gastrointestinal
  • Urologic
  • etc.

If you want to learn more about medications that can cause excessive sweating, I recommend that you visit, which offers a deeper understanding of the topic.

If you suppose that a medication is causing you to sweat, ask your doctor to switch the prescription to see if anything changes.


The list of generalized hyperhidrosis causes can be continued because there are many other diseases and conditions that can cause excessive sweating.  There are:

  • different kinds of cancers,

What Is Primary Hyperhidrosis? The Facts Explained

what is primary hyperhidrosis

Hi everyone,

every time I write a new article, the question “what is primary hyperhidrosis” comes up, because this website is all about helping people that suffer from excessive sweating.  However, the term hyperhidrosis is not very well known.

In fact, I had the excessive sweating problem for many years until I finally found out that hyperhidrosis is the term used for excessive sweating.  After that, I was still confused with that hyperhidrosis was, because heard people claiming that they suffer from hyperhidrosis, which did not make sense to me, because they had a different problem that I did.

After years of doing my research, I have come to a fuller understanding of this terms and others that can be quite confusing.

A Little About Sweating

Over 98% of the worlds population sweats.  There is just a small 1-2% of people that suffer from hypohidrosis, the condition where they do not sweat.  The ones that sweat, have sweat glands all over our bodies.

Sweating is there to primarily regulate our body temperature but also aids the skin to protect our vital organs.  Sweat prevents toxins from coming into our skin, but it also keeps our skin healthy and hydrated.

We all sweat differently, some more and others less.  Some sweat more on their foreheads, others in their armpits, others in their backs, and still others on their feet and palms.  There is a 2-3% of the population that sweats more than necessary and normal.

These individuals (numbers could be significantly higher because many cases are not accounted for because not all people see a doctor when they sweat more than necessary) suffer from hyperhidrosis.

However, before I describe hyperhidrosis a little more in detail, let us look at where sweat comes from and what in our body produces it.  For that, we need to study a little about the sweat glands.

2 Types Of Glands Described

Eccrine Sweat Glands

To understand hyperhidrosis better, we have to look at the 2 types of glands: Eccrine and apocrine sweat glands.  The eccrine glands are the ones that are triggered by the part of your brain that is responsible to cool you down.

People that do not sweat, or whose sweat glands have been altered commonly suffer from headaches, and other symptoms.  Since sweating is there to reduce the body temperature, individuals that cannot sweat when their bodies get warmer, tend to have more difficulties.  For example, being in the hot sun for extended periods can even be dangerous for them.

The eccrine sweat glands are located all over our bodies and are there only to regulate the body temperature.  These sweat glands produce a watery solution that contains few minerals.  With every drop of sweat that comes out of the pores, a little heat is evaporated, thus cooling down the body in a short time.  Since they are all over the body, it does not take long for our body to cool down.

Sweat from the eccrine glands does not smell bad at all, neither does it make you feel all filthy and ready for a shower.

Apocrine Sweat Glands

If you look at the apocrine glands, you will see that they are located deeper underneath our skin than the eccrine glands and their functions differ greatly from those of the eccrine glands.  Also, these are not all over the body.  You will only find them in your armpits, forehead, feet, palms, and groin.

The composition of the sweat they produce is also completely different from the sweat produced by the eccrine glands.  Sweat from the apocrine glands contains proteins, fats, minerals, and salts.  This sweat is a thicker liquid that gets “sticky” if not washed off after some time.

Sweat from these glands does not smell bad itself, but as it is being broken down by bacteria living on our skin, especially in humid and hot body regions, like armpits, groin area, and feet, the breakdown process can be quite unpleasant as much for yourself than for others.

The apocrine sweat glands are not connected to the temperature regulation; they are triggered by our nervous system, in other words, they are pumped by adrenaline.  Therefore, when you are in panic, in great fear, in great emotions, sexually stimulated, these sweat glands start to produce sweat.

It is known that in us humans the apocrine glands are producing an odor only perceived by the brain to attract the opposite sex.

What Is Hyperhidrosis?

Now that we know the functions of each of the sweat glands, we can make sense of hyperhidrosis.

Individuals that sweat excessively, do so no matter what the weather conditions are.  You know that you suffer from hyperhidrosis when you sweat in situations where you would not expect someone to sweat.  It can be during a cold winter night, before writing an examen, while on a date, when dining in at home with family.

When you do your workout routine or work in the hot sun, go into a sauna, you expect yourself to sweat.  The harder you work, the harder you sweat.  However, that is not excessive sweating, because hyperhidrosis, as stated, occurs in circumstances where you don’t think you will sweat.

For example, you have a free day and you decide to stay in pajamas for the day, sitting back and resting, reading a book, watching a movie, among other things.  You are not stressed, you are not in a hurry, but you sit there and sweat.  That is a sign of excessive sweating.

Another example is that you only recently started to sweat more than you are used to when cooking your favorite meal and it happens repeatedly.

That is when you know that you could be suffering from hyperhidrosis.

What Happens In Our Bodies When We Have Hyperhidrosis?

The sweat glands that can be linked to hyperhidrosis are the apocrine sweat glands and not the eccrine glands.  All people who sweat excessively sweat either too much on their feet, palms, groin, forehead, armpits, and sometimes in their neck.  However, you will not see someone with this problem that sweats excessively on their legs, or on their back.  That is because the eccrine glands aren’t triggered to produce more sweat than normal.

Interestingly, someone who sweats excessively is not bound to weather conditions to sweat less or more.  These individuals may sweat excessively in a cool room, and others may sweat when they are not doing anything.  Of course, when it gets very warm, sweating can increase, but that does not necessarily mean that they suffer from hyperhidrosis.

I often hear people say that they suffer from hyperhidrosis during summertime.  That is not true.  When you have hyperhidrosis, you sweat excessively year-round, and sweating is only predictable to some degree.

For instance, I have suffered from this condition ever since my early teens.  I know that when I am going to a social event, I will be sweating.  But there are winter days when I sweat a lot while at home, and there are warm summer days when I sweat little compared to the heat.  Also, there are social gatherings when I sweat a little, and other times I sweat so much that I can hardly deal with it.  Also, I sweat mostly in my armpits.  Sometimes my forehead and groin get sweat as well.

When you suffer from hyperhidrosis, your brain does not stop sending signals to the sweat glands to produce sweat.  It is as if your adrenaline was constantly telling you to produce sweat, even if it is not needed.  Remember, when suffering from hyperhidrosis, you sweat when it is not necessary.

Research has yet to determine why the brain triggers the apocrine sweat glands to produce so much sweat.  It seems like there is a hormonal imbalance when that happens.  However, balancing out the hormones does not give the wanted effects.  Therefore, it is a mystery why that happens.

What Is Primary Hyperhidrosis? Interesting facts

It is primary hyperhidrosis that has me puzzled, and I believe researchers too.  This is the condition in which there is no reason found why an individual sweats that much.

Let me share a few facts about primary hyperhidrosis:

  1. Primary hyperhidrosis affects around 2-3% of the population, as mentioned before.
  2. Primary

Why Do My Armpits Sweat So Much? Here 3 Scenarios Why

why do my armpits sweat so much

Hi everybody,

I think the question “why do my armpits sweat so much?” is a great question and I am happy that you asked it.  It tells me that you are having a real problem and you are looking for a solution.

Did you know that I asked that same question for many years?  I rarely ever asked this question to anybody else, but to myself thousands of times.

I always felt ashamed that my armpits sweat so much and always left huge, I mean huge, sweat marks behind.  It took me years in finding out what clothes and in which colors I could wear to make the terrible sweat marks less visible.

And yet, I do not live in a humid or very hot climate.  Ok, it gets really hot during summer time, but not humid.  But most of the people living here do not sweat so much.  At least that was my perception for many years.

I waited for that day to find somebody with sweat marks.  And you know what?  Shhhh…. although I never saw them again, I remember some faces and some people that had large sweat marks.  What a relief that was for me.  But that did not solve my problem.

You see how sweaty armpits can become an obsession?  Everything seems to go around it.  Whenever someone invited me, usually the first thought was: Who is going to be there and see my sweating and what am I going to wear?

That was plain crazy.

I did my research to stop this problem, but it seemed as if nothing helped.  I even bought an e-book that claimed to stop armpit sweating, but none of the methods that were explained worked.

Let me reformulate what I just said.  It is not that these methods were not effective, they were some great ways to reduce sweating naturally, but with someone suffering from hyperhidrosis, it was not enough.

What Do We Sweat For?

Have you heard the term primary hyperhidrosis?  It is used to describe a condition where you sweat uncontrollably for a  known reason or a non-known reason.

if you sweat moderately every time you get warm, then sweating is a completely normal body function.

You see, our whole body is filled with sweat glands (except in our ears, under our finger-and toenails) that sit right under our skin and are ready to get into action.

Yes, sweating has a specific function: Maintain our body temperature.  Our body comes equipped with the most effective cooling system ever found: Sweating.

Whenever our body’s temperature goes up the normal 98.6 degrees Fahrenheit, our brain quickly sends signals to our sweat glands to start producing sweat as the body is getting warmer.

Sweat glands kick in and do their job by pushing out sweat, which evaporates when coming out of our pores and takes a little heat along.  That is the way our body maintains its body temperature.

Therefore, sweating excessively in your armpits, in the first instance, is great!  It does exactly what it was thought for.

But… Our Body Has 2 Types of Sweat Glands

The eccrine sweat glands are located over your whole body, except where your apocrine glands are found.  I will describe that in just a moment.

The eccrine glands lie just underneath the skin and the watery liquid that comes out is mainly made up of water with few salts and minerals.

These glands come into action as soon as your body is generating more heat, due to external factors such as weather, exercising, working, etc. or internal factor such as dehydration, fever, cardiovascular diseases, among others.

And then we have the apocrine glands which are found in your armpits, groin, palms, feet, and forehead exclusively.  These glands are located a little deeper than the eccrine sweat glands.

These glands produce a thicker yellowish liquid that is made up of water primarily but also carries proteins, fats, minerals, and salts along.

The apocrine glands are not linked to the part in your brain that controls body temperature.  They are linked to our hormones, adrenalin to be more specific.

These glands kick in as soon as you are stimulated because of stress, fear, anxiety, sex, danger, among others.  And they kind of cool down these stimulations.

Interesting fact though is that in some people, these sweat glands have no “off-button”.  Science has not found why in some people the apocrine sweat glands are overly active.  One thing is clear, it is not necessarily due to a hormonal imbalance. It “just” happens for no known reason.

At second glance, if you sweat excessively all the time, even though you are not working or in a warm room, sweating becomes a not-so-great thing anymore as it seemed in the first place.

2 Types of Hyperhidrosis

If you sweat uncontrollably in your armpits, then you a potential candidate of one of the following types of hyperhidrosis:

1) You have primary hyperhidrosis.  Commonly individuals start to develop primary hyperhidrosis during their early teenage years or even in early adulthood.  It never develops in the later stages of life.

The only thing that you know about it that suddenly you start to sweat a lot, but you feel as healthy as before.

After I did my research years ago, I found that I suffer from hyperhidrosis.  Healthwise, there is absolutely nothing wrong with a condition like primary hyperhidrosis.  There are no long-term effects other than the ones that I mentioned: Your confidence and self-image is greatly affected.  And that is enough to look for a solution.

If you suffer from primary hyperhidrosis you can usually tell because it does not follow a pattern.  You can be in the hot sun on some days and will not sweat a drop, and then you can watch a movie in a cold room and still sweat as if you were a leaking container and vice-versa.

2) You have secondary hyperhidrosis.  There is another form of excessive sweating which is not only uncomfortable but needs immediate medical attention in some cases.

Secondary hyperhidrosis is when you sweat excessively but for a reason.  It can happen to anybody at any age.  It comes suddenly and it will go away once you find the cause and you get a cure for it.

If you have only recently started to sweat excessively and you are over 25 years old or you know of somebody that is not even a teenager yet, watch sweating closely.  It could mean diabetes, cardiovascular disease, pregnancy, fever, cancer, tumors, hyperthyroidism, obesity, etc.

However, most of the time, sweating will not be the first sign of these diseases, but it will be a symptom along the way.

Also, secondary sweating usually has a pattern.  For example, you sweat only on the right side of the body, or just in your armpits, or at certain times of the day, or under certain circumstances, whereas primary hyperhidrosis does not follow a pattern.

Is There Something I Can Do About My Sweating?

Definitely, there are things you can do that will give you relief.

However, first figure out why you sweat excessively.  Is it just because the weather is becoming warmer and you work outside or because you do not have air conditioning?  Or is it that you are sweating uncontrollably in your armpits for a long time already and there is no reason for it?  Or is there an underlying health issue that you are aware of or maybe even unaware of?

For each of the above-described types of hyperhidrosis, there is something you can do.  Let’s find out what exactly.  I’ll describe three different scenarios.

Scenario #1

You are doing your exercise routine and you sweat a lot in your armpits.  But once your body cools down, your sweating ceases and will not come back until your body gets warm again due to thick layers of clothing, working, doing chores, running errands, warm and humid climates, or others.

If that is the case, you can do one of the following:

1) Wear appropriate

How To Stop Nervous Sweating Today: How I Stopped It Completely.

Last updated on September 11th, 2018 at 02:01 am

how to stop nervous sweating

Has it happened to you that you are invited to your best friend’s wedding and you just wonder what you should put on because you know ahead of time that you will have huge sweat marks in your armpits because of excessive sweating?

Things are even worse for you when you are asked to wear a specific color of a dress shirt or dress. Let’s assume you are the groom’s best man or the bride’s maid of honor. You will have to wear whatever the bride and groom will choose for you.

Not only to weddings but also to all kind of social events, excessive sweating in your armpits, forehead or palms is highly embarrassing.

That presentation that you have to give, and you know that you will want to show something, and immediately thoughts like “…but everybody will see my sweat marks”, or “… I cannot do that because I sweat too much and that is awful” flood your brain and off are you are to a vicious cycle.

If you tend to sweat excessively when you go to social gatherings, you have a condition called nervous sweating.

Nervous sweating is when you sweat because you get nervous. But how to stop nervous sweating?

Understanding Nervous Sweating

Nervous sweating affects people greatly because it is a condition that makes them insecure and very nervous about themselves.

When you dread sweating the most, that is when it happens the most. All the time you have to give a speech, meet new people, meet well-known people, go to weddings, funerals, church, etc., your fear about sweating triggers your nervous system and that again triggers the sweat glands.

Some consider nervous sweating a social phobia. However, I do not think that this is the case. If you sweat excessively when you get nervous, I can only guess that you always sweat easily and even excessively.

I have faced nervous sweating for many years, but I consider it to be a case of primary hyperhidrosis and not so much a social phobia.

What Is Primary Hyperhidrosis?

The term primary hyperhidrosis is used to describe a condition where a person sweats excessively for no known reason. That means that you could not find a cause for this sweating.

Yet hyperhidrosis only happens in your armpits, palms, feet, groin, and forehead. You do not sweat all over your body when you have hyperhidrosis. That is because there are the apocrine sweat glands, which are connected to your endocrine system.

Sweating is actually for controlling body temperature, but especially in people suffering from primary hyperhidrosis, the apocrine sweat glands apparently have a different view of that important body function. Nevertheless, everybody that gets into a serious predicament will start to sweat at some point because of these sweat glands.

Adrenaline triggers these sweat glands and they go into production. Research is not sure what causes hyperhidrosis, but one thing is sure, in people suffering from this condition, the sweat glands do not regulate this sweating function correctly.

It is known that people suffering from hyperhidrosis produce at least 6 times more sweat than the body requires cooling down.

There are more causes of excessive sweating.  Find out here .
