Night Sweats for Men and Women – There is a solution!

Did it ever happen to you that you woke up in the morning and your pajamas and bedding were soaking wet? You might suffer from night sweats. Night sweats for men and women is a common phenomenon. What are night sweats? Why does it happen, how do you deal with it? And how long does night sweats last?

What are night sweats?

The body’s temperature gradually drops during sleep. However, various factors can interfere with this process and cause the body to overheat and produce increased sweating at night. These can be external factors such as overheating the room, certain eating habits, mental state, and various medical-related problems.

Many of us occasionally sweat during the night, regardless of the weather. A US study of 2,267 patients who visited their family doctor found that 41% reported night sweats in the past month. Night sweats are those that make a person feel like they “woke up in a puddle.” They wake up when their clothes, bedding, and sometimes even the mattress are wet. Night sweats can interfere with sleep properly and even make a person wake up several times during the night.

This is an unpleasant condition, and if it persists, you should seek professional medical advice.

Sweating occurs in response to changes in the body or environment temperature. As well as excessive clothing, emotional state, or following eating a particular food should not be a concern. However, night sweats can indicate a hormonal problem, infectious disease, malignant disease, or other problems.


In general, night sweats may also be accompanied by symptoms such as fever, weight loss, local pain, cough, diarrhea, or other symptoms.

Causes and Risk Factors for Night Sweats

for Women and Men

Part One

Main reasons for night sweats:

  1. Hormones: Nocturnal sweating is one of the symptoms that characterize menopause. Some women even report several such incidents at night accompanied by significant sleep disturbance. Some even suffer from hot flashes throughout the day. However, a simple medical examination may help clarify if a hormonal imbalance is the source of the problem. Young women who replace birth control pills and those who are pregnant or a few weeks postpartum may also suffer from night sweats. This is due to the effect on hormone levels in their body. If you or your daughters have had hormonal contraceptives replaced or are pregnant or postpartum, you should consult your doctor to find out how to treat the problem.

2. The thyroid gland: People who suffer from hypothyroidism tend to sweat at night. Also, while people with hyperhidrosis during the day. The thyroid gland produces two hormones – triiodothyronine and thyroxine. Research shows that their underproduction and overproduction are characterized by excessive sweating.

3. Medications: Night sweats are a known side effect of many medications, including antidepressants, hormonal therapies of various types designed for patients with cancer and diabetes, steroids, and painkillers. Also, medications to lower blood pressure.

4. Risk of heart disease: A study published in 2014 indicated a statistical association between frequent night sweats and risk of heart and arterial disease. The comprehensive study, which examined more than 11,000 women over 14 years, indicated additional connections: overweight, high blood pressure, and/or diabetes are also prone to night sweats. It is difficult to determine the cause and outcome. And yet, it is clear that sweating is part of a spectrum of symptoms that characterize people at high risk for heart disease.

5. Sleep problems:– Some people suffer from restless sleep accompanied by many upheavals and shifts due to unpleasant dreams or restlessness. In such a case, sweating is a reaction of our body to a lot of motility, the pressure we feel during dreams, etc. If your partner remarks that you have moved out of sleep or wake up in the morning with a constant feeling of tiredness, remember bad dreams, you probably should improve the quality of your sleep. The good news is that there are many ways to gain a better sleep, from diet to the type of lighting in your bedroom.

6. Anxiety: Anxiety is a mental condition that is sometimes manifested in physical symptoms. One of the familiar symptoms of this is night sweats.

7. Bacterial or viral infection: When the body fights disease or infection, night sweats can be a side effect of the battle. As a result, it is not uncommon to come across people who suffer from night sweats days and even weeks after illness or infection. In other words, if you have been sick recently.

If night sweats have an unpleasant odor or are accompanied by diarrhea or vomiting, it may be an infection. Bacterial or viral infections can lead to night sweats. Blood tests can easily detect them as they will be marked by many white blood cells called lymphocytes (for viral infection) or neutrophils (for bacterial infection). These processes occur parallel with an infection or inflammatory process in the thyroid gland, appendicitis or tonsillitis, and heart inflammation. This will manifest in a prolonged fever that does not go down or in a murmur that the doctor can check and hear.

8. Apnea: Sleep apnea is a condition that causes apnea in the middle of sleep, usually several times a night. A 2013 study examining 822 people suffering from apnea showed that night sweats were three times more likely to occur in people suffering from apnea and untreated. Therefore, in case of apnea, we recommend consulting a doctor for appropriate treatment.

9. Allergy: In sporadic cases, night sweats are associated with an allergic reaction that triggers the body’s sweat mechanism. Suppose you suffer from additional allergy symptoms, which increase especially in the evening when you go to bed or in the morning when you wake up—in that case, sleeping several nights in another room or house and seeing if the condition improves. If you experience a change after the experiment, it may indeed be an allergenic cause of excessive sweating in men or women. Contact a doctor to try to identify the allergen to treat it accordingly.


10. Hyperhidrosis: This is a disorder of general hyperhidrosis in the body, usually in the armpit area, the hands and feet, and the various regions of the face. This condition, which is not dangerous, can cause excessive sweating that can disrupt the daily routine. Nocturnal sweating is one of the symptoms of this disorder.

11. Hypoglycemia: This is a condition in which the blood sugar level drops and can cause night sweats in some people. Other signs of hypoglycemia include weakness, dizziness, headache, or irritability. It may affect people on the day they have not eaten for long hours or differentiate those who need insulin or medications to swallow for diabetes. If you experience a general change in your health that started at or near night sweats, see a doctor soon.

12. Malignant diseases (cancer): Hodgkin’s lymphoma and non-Hodgkin’s lymphoma can cause night sweats. In this case, night sweats are one of the trigeminal symptoms that characterize lymphomas: fever, weight loss, and night sweats—no need to stress and excessive sweating in men or women. There are also many other reasons, but if you suffer from excessive sweating along with fatigue, weight loss, and/or enlarged lymph nodes, it is worth getting tested. Some types of lung cancer and mesothelioma (a malignant disease of the lung lining) may also cause night sweats; Carcinoid syndrome can cause significant sweating at night.

13. Poor nutrition before bed: Pay attention to what we eat before we go to bed. Night sweats for men and women can be a result of bad eating. Some foods may lead many of us to increased sweating at night. Highly spicy foods, including Tabasco sauce, vinegar, or mustard, and vegetables like garlic, onions, and hot peppers or fatty foods like hamburgers, encourage acid production in the stomach, making it work harder. The strenuous activity of our stomach can manifest itself in sweating throughout the body as well as heartburn. It doesn’t mean you can’t enjoy a delicious dinner, instead of a fatty hamburger, prefer turkey; this is due to the tryptophan acid it contains, which is an amino acid that encourages sleep and helps your stomach rest and your body relax;

14. Autoimmune diseases: This is a condition in which cells of the immune system attack body tissues. Rheumatoid arthritis, osteoarthritis, vasculitis, or bone loss are just some autoimmune diseases that can be accompanied by pain in the joints and muscles and extreme night sweats. The phenomenon of hyperhidrosis also appears among celiac patients. If you have been diagnosed with an autoimmune disease, sweating may just be telling you something you already know.

In some cases, night sweats characterize those who suffer from these diseases in old age. So if you or your loved ones suffer from one of these diseases, you must consult a doctor to treat the unpleasant side effects properly.

15. Consumption of alcoholic beverages or caffeine during the day: Drinking caffeine during the day, not even near sleep, can cause excessive sweating in women and men at night. Many assume that if they do not drink a cup of coffee or black tea before bed, they won’t suffer from the effects of caffeine. However, the stimulant effects of caffeinated beverages can stay in your bloodstream and thereby make you sweat overnight. Also, many people consume alcoholic beverages in the evening. They, too, can significantly affect some of us and cause night sweats in men or women.

16. Infectious diseases: tuberculosis, brucellosis, typhoid, myocardial infarction (infectious endocarditis), and AIDS can cause hyperhidrosis in men and women.

In many cases, night sweats are a temporary and transient phenomenon, which does not necessarily indicate a worrying problem. However, in cases of prolonged night sweats, night sweats that wake up regularly, and night sweats accompanied by additional symptoms that have no clear explanation, such as weight loss, fever, indigestion, etc., medical advice should be sought.

Diagnosis and Testing

If sweating is an ongoing event, we highly recommend consulting a doctor. A medical history and a physical examination by a doctor will usually be the intention for the appropriate diagnosis. However, suppose the history and physical examination do not reveal the medical condition that causes the patient’s symptoms. In that case, a preliminary exam should be started, including blood tests, urine tests, and a chest x-ray. Depending on the results of these tests, your doctor may recommend additional tests.

Possible Complications

Significant night sweats, which cause awakening and interfere with normal sleep, require a medical examination to rule out several diseases and health problems. However, it is important to remember that in most cases, e a reaction to environmental conditions during sleep. Therefore, in most cases, any night sweat should not be seen as a hint of the existence of an underlying disease. Certainly not a life-threatening one.


Prevention of night sweats is related to the prevention of the underlying cause or disease leading to sweating. However, when experiencing night sweats, make sure not to sleep in a too-hot room or under many blankets. If this does not help, consult a doctor for a diagnosis.

How long do night sweats last?

Night sweats will usually continue as long as the cause has not been treated. Regarding night sweats during pregnancy or after birth, we know how to answer the question of how long night sweats last.

According to studies, about 35% of women suffer from the phenomenon during pregnancy and 29% after childbirth.

Postpartum night sweats occur due to low levels of estrogen. The body releases two significant hormones, called progesterone and estrogen, in large amounts during pregnancy. Therefore, changes in the levels of these hormones can cause an increase or decrease in body temperature.

So how long does night sweats last?

Usually about two weeks, they do not depend on additional factors and can last for six weeks and even longer among breastfeeding women. Breastfeeding causes menopausal-like syndrome. There is no ovulation, and menstruation returns in each woman at a different time. During this period, women can continue to sweat both at night and during the day.

How can this phenomenon be alleviated?

In most cases, the causes of night sweats for men and women are unclear, and it is not a life-threatening disease. However, this is a phenomenon that can impair the quality of life. How, then, can it be alleviated?

  1. Avoid stimulants: If you are prone to hyperhidrosis, avoid drinking alcohol or coffee as early as noon. Drinks that contain these substances can cause hyperhidrosis during the night.
  2. Adjust the sleeping environment: Check that your pajamas, bedding, and even the mattress. Make sure they are made of suitable materials that allow the body to “breathe.” Do not overheat the bedroom.
  3. Avoid strenuous exercise before bed: Sports activities have many benefits, including increasing the rate of metabolism. However, it also raises the body temperature. Therefore, the recommendation is not to engage in a strenuous exercise about two hours before bedtime.
  4. Have a light dinner: Sometimes, a dietary change can also help. For example, try to make your dinner light and include grains and vegetables. Also, be sure to eat dinner away from bedtime and not within the hour before bedtime.
  5. Avoid over-coverage: Even in winter, it is important to keep your foot out of the blanket when it is cold. This will help your body regulate the temperature and reduce excessive sweating. In case of night sweats during pregnancy or after childbirth, you should cool the body as much as possible. Sleep with windows open or turn on a fan or air conditioner. It is recommended to use 100% cotton bedding to absorb sweat.
