Sweating is the body’s natural cooling mechanism and is usually activated in hot weather or while exercising. However, there’s a time and a place for it. If you sweat while you sleep, it can be both uncomfortable and alarming.

While there can be many reasons for night sweats, learning to recognize the symptoms and causes will help you understand this condition. So, is it normal to sweat while you sleep? We’ll look at the causes of this phenomenon below.

Why do you sweat while you sleep?

No one likes to wake up in a puddle of sweat in the middle of the night. In order to figure out the possible cause of night sweats, it’s important to consider all the factors that influence this.

The first and most obvious one to consider is the temperature and general comfort of the environment. Heat isn’t the only environmental factor that can cause night sweats; humidity can also play a significant role.

Other possible contributors to night sweats can include heavy blankets or pajamas, a general discomfort caused by an old mattress, or a noisy environment.

The next thing to consider is your overall health. Have you changed your diet? Have you been feeling fatigued? Some flu symptoms include fever, which is a normal response to infection.

Night sweats may be the result of fever if you notice cold symptoms or the flu itself within a night or two. However, beyond this, it could be something more serious.

One of the most common causes of night sweats is hot flashes associated with menopause, which result from hormonal changes in the body. A sudden drop in estrogen production can cause confusion in the hypothalamus, causing a woman’s skin temperature to rise by up to 6 degrees almost instantly.

Even men aren’t exempt. Those who are testosterone deficient or who are taking medications that block this hormone can also experience similar effects. Most men won’t admit that they’re experiencing hot flashes, but androgen deprivation can cause night sweats.

1. Medications

Many prescription medications can increase your heart rate and cause blood vessels in the skin to dilate, which can lead to excessive sweating. Antipyretics, or fever-reducing medications, are the most common.

When experiencing flu symptoms, many people take aspirin or similar remedies. Although these are often effective in reducing fever, they can also cause night sweats. Similarly, other medications that can cause night sweats include antidepressants.

2. Health problems

Infectious diseases, such as tuberculosis and AIDS, are also known to cause night sweats. A persistent fever, which is often accompanied by night sweats, is common among people who have tested positive for HIV.

On the other hand, Hodgkin’s disease, a type of lymphoma, is another infectious disease that often causes fever and night sweats in patients.

3. Unhealthy eating habits

Alcohol abuse at night is also to blame for some people’s night sweats. Although a glass of wine before bedtime can help you fall asleep, when sleep is alcohol-induced its effects are less restorative; these people are more prone to headaches and night sweats.

Another possible factor that could cause night sweats is spicy food. Although it may not give you immediate discomfort while eating, it may increase your skin temperature as you digest these foods.

On the other hand, doctors have also identified that too much caffeine can exacerbate sweating in people who already sweat excessively naturally.

4. Hyperhidrosis

Some people suffer from a condition called hyperhidrosis, which causes frequent and excessive sweating during the day and at night. If you’ve ruled out all other possible causes of night sweats, you may be suffering from hyperhidrosis; you should schedule an appointment with your doctor to discuss it.

Natural solutions for night sweats


The first and most obvious thing is to look at your thermostat. Although most doctors recommend a temperature of 18-22°C for sleeping, everyone is different; you should experiment to find out what’s best for you.

If you sleep with your partner and he or she prefers a warmer or cooler temperature, try wearing several light layers of bedding.

Also, eliminating the likely causes of stress and anxiety is also a good idea. Nervousness and anxiety are common causes that can make us sweat.

For the above reason, if you’re getting married or have a job interview, expect to sweat a little more than usual. However, if the night sweats continue for several weeks after the big day, you should probably seek medical advice.

Both men and women with excessive sweating due to menopause or andropause can take black cohosh tea or black cohosh supplements. Black cohosh is a native plant found in many parts of North America; it has been used to cure various ailments.

Red clover is another medicinal herb taken to alleviate the severity of hot flashes and night sweats. However, its effects haven’t been as good as black cohosh.

With all this, you may already have an idea of why you sweat while you sleep. Remember, if you make changes and nothing works, you should see a doctor to rule out more serious problems.
