Why Do I Sweat When I Nap? Fascinating Explanations


Are you asking yourself the question: Why do I sweat when I nap? This is a dilemma that millions of people are curious about. Is it a good or bad indicator of health? I will answer this query based on scientific facts. You may find the answer fascinating.

What is Sweat? Where does It Come from?

Sweat is a natural fluid produced by the sweat glands to control body temperature. When the body temperature goes more than 37 degrees Celsius, this stimulus is fed to the hypothalamus, which will ‘command’ the sweat glands to produce sweat.


What is A Nap?

This is a short sleep; from a few minutes to 90 minutes, more than that isn’t recommended, unless you have insufficient sleep the night before. Naps are important and they should not be avoided because they boost mental activity and performance.

The importance of naps

Now, let’s go to the major question: “Why do I sweat when I nap?”

There are Various Explanations Why do I Sweat When I Nap

1. Physiological Explanations (Normal Body Response)

It’s natural to sweat when the weather is hot during a nap, but it should not be excessive.

This process of sweating has been explained earlier. Therefore, sweating is a normal reaction of your body when your body temperature is elevated. Examples of instances when body temperature is elevated are:

  • When the room temperature is high
  • When you wear extremely warm clothing
  • During hot weather

Another physiologic explanation is that when a nap takes longer than 30 minutes, the body becomes uncomfortable and warm, and hence sweating is triggered.

So, naps that are too long more (more than 60 minutes), may have a negative effect: headache, and decreased mental capacity.

An example:

A person who had sufficient sleep the previous night can benefit more from a 10 minute nap, than an hour’s nap. The hour’s nap will make him sluggish, ‘tired’ and sweaty.

Certain substances can increase sweating, such as alcohol, spicy foods and sweets. Thus, if you took in alcohol or spicy foods before napping; these can cause excessive sweating.

Here’s more about hyperhidrosis (excessive sweating).

2. Pathological Explanations

There are also pathological reasons or diseases than can cause hyperhidrosis (over sweating) during a nap or at night time. This can be a cause of concern.

The underlying reason of the sweating must be determined first. Once the ‘culprit’ is found, therapeutic measures should be instituted to prevent the worsening of the disease.

Diseases associated with sweating when napping or sleeping are:

  • Diabetic patients, who are taking in medications, such as insulin injections and oral medications. Hypoglycemia may occur (low sugar levels), causing the sweating.
  • Menopausal men and women: For women, the fluctuating levels of estrogen can cause excessive sweating during naps and at night time. Sweating occurs when an attack of hot flashes comes, and the body has to sweat to balance the body temperature.
  • Autoimmune diseases, such as Human Immunodeficiency Virus(HIV) and Acquired Immunodeficiency Syndrome (AIDS). Evaluate your symptoms, against that of DM and HIV to see if you have,indeed, the disease.
  • Other illnesses such as, stroke, brain damage, epilepsy, hyperthyroidism, migraine and cerebral palsy.

Steps to Get Rid of Sweating When Napping


Step #1 – Determine The Cause of Sweating

To be able to stop your excessive sweating when napping, you have to get to the root of the problem. Refer to the explanations above to know which tests you have to undergo. You can consult your doctor to ensure that the tests are done reliably.

The reason for your hyperhidrosis during a nap may be serious, or just physiological. But it’s best to be certain.

Step #2 – Treat The Underlying Condition

When the correct diagnosis is done, you should undergo suitable treatment. Treating the illness will eradicate its symptoms (sweating).

If the cause is physiological, then adaptive steps should be implemented. An example is by wearing thin clothing when the weather is warm.

If the cause is pathological, therapeutic measures must be done immediately. Examples are HIV, which can progress to AIDS. HIV/AIDS have no cure but early prevention of the growth of the virus can be beneficial.

Step #3 - Observe Proper Hygiene

You must also observe proper hygiene after doing steps #1 and #2. When you take a shower before a nap, you’re cooling the body; so, there will be lesser chances of sweating.

Step #4 – Live A Healthy Life

This aspect is almost always included when treating diseases, because it plays a crucial role in maintaining a healthy body. Eating right, avoiding alcohol, spicy foods, too much sweets and fats are your pathway to a healthy life.

Hydrate yourself often to prevent acquiring more diseases to your already existing health problem.
