Night sweats, characterized by excessive sweating during sleep, can be an uncomfortable and disruptive experience for many men. While sweating is a normal bodily function to regulate temperature, night sweats are not typically caused by a warm bedroom or heavy blankets. Instead, they are often triggered by internal physiological processes or underlying health conditions. These episodes can range from mild dampness to soaking through your pajamas and bedding, leaving you feeling chilled and needing to change clothes in the middle of the night.
Both men and women can experience night sweats due to similar factors like infections or stress. However, some causes are more specific to men. While menopause is a well-known cause of night sweats in women, hormonal imbalances also play a significant role in men, particularly low testosterone levels. Furthermore, certain health conditions that are more prevalent in men can also contribute to nighttime sweating. Understanding the reasons behind “Why Do I Sweat When I Sleep Male?” is the first step toward addressing this issue and improving your sleep quality.
It’s important to note that while occasional night sweats might be harmless, frequent or severe episodes could indicate an underlying health concern that requires attention. Identifying the potential causes of night sweats in men can help you determine when it’s necessary to seek medical advice and explore appropriate treatment options.
Common Causes of Night Sweats in Men
Several factors can contribute to night sweats in men. These can range from lifestyle factors and hormonal imbalances to underlying medical conditions. Here are some of the most common reasons why you might be experiencing night sweats:
Low Testosterone Levels (Male Hypogonadism)
Low testosterone, also known as male hypogonadism, is a significant contributor to night sweats in men. Studies indicate that approximately 38% of men over the age of 45 experience low testosterone. Even in otherwise healthy men over 60, the likelihood of having low testosterone is around 20%.
Hypogonadism can stem from issues with the testicles (primary hypogonadism) or problems in the brain regions that control hormone production (secondary hypogonadism). Besides night sweats, other symptoms of low testosterone include:
- Decreased libido and erectile dysfunction
- Loss of body and facial hair
- Unexplained fatigue and weakness
- Reduced muscle mass and increased body fat
If low testosterone is the culprit behind your night sweats, treatment options such as testosterone replacement therapy or addressing the underlying cause of hormone imbalance may be recommended by your doctor.
Stress and Anxiety
Stress and anxiety can significantly impact your body’s sweat glands, making them more reactive. Individuals experiencing high levels of stress or anxiety, whether short-term or chronic, are more prone to night sweats. Research even suggests that the stress induced by mentally challenging tasks, like solving math problems, can increase sweat gland activity.
While anxiety disorders are diagnosed more frequently in women, men are often less likely to report or seek help for mental health concerns. Stress responses can also manifest differently between genders; for example, men may experience more physical symptoms like changes in blood pressure. However, the fundamental physiological response to stress, including increased sweating, is similar in both men and women. Managing stress through relaxation techniques or professional help can potentially reduce night sweats linked to anxiety.
Obstructive Sleep Apnea (OSA)
Obstructive sleep apnea (OSA) is a sleep disorder characterized by repeated pauses in breathing during sleep. These pauses, or apneas, are often followed by gasping or choking sounds, and loud snoring is a common symptom. It’s estimated that 3% to 7% of Americans have OSA, and it’s considerably more prevalent in men – three to five times more common than in women. This higher prevalence in men is attributed to factors such as airway structure, obesity rates, and hormonal differences.
Nearly one-third of men with OSA report experiencing night sweats. This rate is significantly higher, about three times, compared to the general population. Fortunately, effective treatment for sleep apnea often leads to a resolution of associated night sweats.

Medications
Certain medications are known to induce excessive sweating, including night sweats, as a side effect. Common culprits include:
- Selective Serotonin Reuptake Inhibitors (SSRIs) and Tricyclic Antidepressants: These medications, used to treat depression and other mental health conditions, can affect the body’s temperature regulation.
- Aspirin, Ibuprofen, and other Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): These over-the-counter pain relievers can sometimes cause sweating, particularly when taken in higher doses.
- Hypoglycemic Agents for Diabetes: Medications used to manage blood sugar levels in people with diabetes can occasionally lead to night sweats.
- Corticosteroids: Such as cortisone, these medications, used for inflammation and various other conditions, can also cause increased sweating.
If you suspect that a medication might be causing your night sweats, it’s crucial to consult your doctor. Never discontinue or alter the dosage of prescribed medication without professional medical advice.
Infections
Infections, both minor and serious, can trigger night sweats. When your body fights off an infection, it releases inflammatory substances that temporarily raise your body’s temperature set point. This process usually starts with chills and shivering to increase core body temperature, followed by excessive sweating to cool down once the body’s temperature regulation returns to normal. This cycle can repeat throughout the course of an infection.
While common infections like the flu can cause night sweats, they can also be a symptom of more serious infections such as:
- Human Immunodeficiency Virus (HIV)
- Tuberculosis (TB)
- Endocarditis (infection of the inner lining of the heart chambers and valves)
- Brucellosis (an infectious disease caused by bacteria from unpasteurized milk or undercooked meat)
Hyperhidrosis
Hyperhidrosis is a condition characterized by excessive sweating that occurs without typical triggers like heat, exercise, or stress. The sweating can be so severe that it soaks through clothing and may lead to skin problems due to constant moisture. While some individuals develop primary hyperhidrosis with no identifiable underlying cause, secondary hyperhidrosis can be caused by various medical conditions and medications.
Hyperhidrosis affects men and women at similar rates. Treatment approaches vary depending on the cause and may include topical or oral medications, botulinum toxin injections to block nerve signals to sweat glands, or, in rare cases, surgery.
Exercise
Interestingly, regular exercise can sometimes contribute to night sweats. There’s evidence suggesting that consistent exercise can lower the body’s thermoneutral zone, causing you to sweat at lower temperatures than usual. For instance, prolonged exercise in hot environments can alter your thermoneutral zone and potentially lead to night sweats. While exercise is beneficial for overall health, night sweats can also be a sign of overtraining in athletes. It’s important to discuss any new or concerning symptoms with your doctor, especially if you are engaging in intense physical activity.
Other Potential Causes
Night sweats are a common symptom with a wide range of potential causes beyond those already mentioned. While night sweats themselves are not directly linked to an increased risk of death, they can be a symptom of serious underlying conditions. These include:
- Certain cancers: Such as lymphoma and leukemia.
- Autoimmune disorders: Like rheumatoid arthritis or lupus.
- Neurological conditions: Including autonomic neuropathy.
- Hormonal disorders: Such as hyperthyroidism.
When Should You Talk to Your Doctor?
Night sweats are a relatively common experience. However, because they can sometimes indicate underlying health conditions that require medical attention, it’s important to consult your doctor if you are concerned. Seek medical advice if your night sweats are persistent or accompanied by other symptoms, such as:
- Disrupted sleep patterns
- Persistent fatigue, weakness, or excessive daytime sleepiness
- Unexplained weight loss
- Noticeable mood changes
- Fever
Even if you don’t have an underlying medical condition causing your night sweats, if they are consistently disrupting your sleep and comfort, your doctor can help explore treatment options to manage the sweating itself and improve your sleep quality.
Tips to Reduce Night Sweats
If your night sweats are linked to an underlying medical condition, treating that condition is usually the most effective way to reduce them. In addition to addressing any underlying causes, you can take several steps to sleep more comfortably and minimize night sweats:
- Keep Your Bedroom Cool: While night sweats are internally driven, maintaining a cool bedroom environment can enhance comfort and potentially reduce sweating. Use air conditioning, consider a cooling mattress, and opt for breathable bedding materials. Aim for a comfortable room temperature conducive to sleep.
- Wear Comfortable Sleepwear: Choose loose-fitting pajamas made from breathable, moisture-wicking fabrics like cotton. This allows for better air circulation and helps sweat evaporate more efficiently, keeping you cooler and drier.
- Practice Relaxation Techniques: Stress and anxiety can exacerbate night sweats. Incorporating relaxation techniques into your bedtime routine can be beneficial. Try meditation, mindfulness exercises, guided imagery, or deep breathing exercises to reduce stress levels and potentially minimize night sweats. Cognitive behavioral therapy or hypnosis, with the guidance of a professional, may also be helpful for managing stress and anxiety-related night sweats.
- Avoid Dietary Triggers: Certain foods and beverages can trigger sweating and affect your internal temperature regulation. Limit or avoid alcohol, caffeine, and spicy foods, especially in the hours leading up to bedtime, to potentially lessen night sweats.
- Maintain a Healthy Weight: Excess weight can contribute to night sweats in some individuals. Obesity is also a risk factor for other conditions that cause night sweats, such as sleep apnea. Maintaining a healthy weight through diet and exercise can be beneficial for overall health and may help reduce night sweats.
Still Concerned About Night Sweats?
If you’re still wondering “why do I sweat when I sleep male?” and are experiencing persistent or concerning night sweats, it’s always best to consult with a healthcare professional. They can help determine the underlying cause and recommend the most appropriate course of action for you. Don’t hesitate to discuss your symptoms with your doctor for personalized advice and treatment.
