Night sweats are common in both women and men. Women often experience night sweats during menopause due to hormonal imbalances. However, night sweats are also common in men. The following article is going to discuss night sweats, or excessive sweating during sleep, in men.

There are several reasons why people experience night sweats, such as hormone-related conditions, low blood sugar, or neurological problems. In order to distinguish whether or not you are experiencing a medical condition, keep reading the following article. If you are concerned or have more questions, make an appointment and visit your doctor. Speak to a health professional you trust.

What are night sweats?

So, what exactly are night sweats? And what causes them? If you keep your room warm or wear thick clothing while you sleep, the temperature may cause you to sweat at night. However, if you experience severe hot flashes at night, you most likely have night sweats. Night sweats occur when you wake up in soaked sheets and clothes. Medical conditions or diseases cause night sweats, which is unrelated to a hot environment.

Although it is common to sweat at night, it is difficult to distinguish if you are experiencing night sweats or just excessively sweating. In a study of over 2,000 patients, 41% described experiencing night sweats to their doctor. In other words, several people experience sweating at night, though it may not necessarily be authentic night sweats.

How does one distinguish night sweats from sweating? As mentioned previously, night sweats are associated with medical conditions or illnesses. Night sweats occur repeatedly and involve extreme perspiration. Additionally, night sweats have several symptoms, such as hot flashes, fever, weight loss or gain, and diarrhea. There are various symptoms associated with night sweats, which is why it is important to speak to your doctor if you believe you are experiencing night sweats.

What causes night sweats?

There are several things that may cause night sweats, including your medications or medical conditions. Below are lists of both disorders and medications that may cause night sweats.

Medical Conditions or Disorders

  • sleep disorders (for example, obstructive sleep apnea)
  • anxiety disorders
  • Hodgkin’s lymphoma
  • leukemia
  • myelofibrosis
  • autoimmune disorders
  • tuberculosis (TB)


  • antidepressants
  • hypoglycemic agents
  • hormone therapy (or hormone-blocking drugs that are used to help with certain cancers)


In most cases, night sweats are not serious. However, night sweats may be an indicator of a bigger health problem. Research shows that night sweats may be an indicator of autoimmune diseases, heart problems, or even sleep apnea. The likelihood for someone with night sweats to experience these conditions is fairly low. Despite this information, it is still important to speak to your doctor if you experience night sweats.

If you are concerned about night sweats, there are steps you can take to treat them. Monitor your body temperature at least two times a day to determine if you have any fevers. In addition, track any other symptoms you may be experiencing in order to accurately inform your doctor of your situation.

More importantly, in order to treat your night sweats, you need to treat the medical condition or disease causing them. One way to determine what causes your night sweats is going to see your doctor. In the meantime, make sure to avoid eating spicy foods before you go to bed and sleep without extra clothing or blankets to keep a cool environment.

Low Testosterone Levels

Night sweats in men are often linked to low levels of testosterone. Also known as low T, low testosterone levels are fairly common among men. Low T is connected to night sweats because testosterone is the main sex hormone in men. Similar to women during menopause, low T is related to hormonal imbalances. If low T is responsible for your night sweats, it is possible for your doctor to suggest hormone replacement therapy. Hormone replacement therapy is a treatment option that can help with your night sweats as well as other symptoms caused by low T.

Symptoms of low T include low energy, increased body fat, moodiness, hot flashes, low libido, and erectile dysfunction. If you are experiencing any of these symptoms, it is likely that you have low testosterone levels.

In conclusion…

Sweat is natural and, in fact, healthy. Sweating allows us to regulate our body temperatures by keeping us cool. However, excessive sweating is uncomfortable and is a sign of your health conditions. Night sweats in men are fairly common, especially considering the impact low testosterone levels can have on the body. Do not ignore your symptoms, and talk to your doctor today.
