Schedule to visit your doctor if you notice any strange rashes, a drastic reduction of appetite, or experience swelled lymph nodes alongside severe sweating.

The Common Causes of Night Sweats In Men

There is a wide range of reasons why men suffer night sweats. They may occur due to non-medical causes such as taking a hot shower, having a hot drink, or working out shortly before going to bed, but some health issues can also cause night sweats in men.

1.Hormone Disorders

Hyperthyroidism, carcinoid syndrome, and pheochromocytoma are the major hormone conditions closely associated with night sweats.

This is how it occurs; the hypothalamus, the part of the brain responsible for body temperature regulation and has the responsibility of releasing and inhibiting hormones, may have trouble regulating temperature due to hormonal imbalances leading to night sweats. This may be corrected by hormone replacement therapy.


Particular drugs have often been associated with night sweats. Antidepressants (selective serotonin reuptake inhibitors) and fever-lowering medicines such as acetaminophen and aspirin may cause sweating ironically.

Talk to your doctor about adjusting your medication if you experience night sweats after starting a new medication or having night sweats for more than a week. Other common drugs known to lead to night sweats are steroids, diabetes medications, phenothiazine, and hormone therapy medications.

3.Serious Infections

Most infections cause fever which in turn results in night sweats. Human Immunodeficiency Virus (HIV) and bacterial infections such as tuberculosis are major infections wherewith night sweats as one of the main symptoms.

Other bacterial infections like osteomyelitis (inflammation of the bones) and endocarditis (inflammation of the heart valves) may also cause night sweats. These infections also tend to have some related noticeable symptoms such as body pain, weight loss, aching muscles or joints, fatigue or general weakness, lack of appetite, chills, and fever.

4.Anxiety and Stress

Sweating can be caused by stress and emotional problems. Sometimes when you are dealing with stress and anxiety, you are likely to experience increased sweating. You tend to sweat more during the day and night as well when you are worried about something.

Although people experience anxiety and stress differently, they may have more emotional symptoms than physical symptoms and vice versa. Here are other signs you may experience under severe stress and anxiety: difficulty sleeping, fear, rapid heart rate, tension, worry, aches or pains, and rapid breathing.


Normally, sweating occurs in response to warm temperatures, nervousness, fear, and activity. Still, in other times, the nerves that are responsible for activating your sweat glands tend to send signals even when sweating is not needed.

This causes excessive sweating across your entire body or maybe in particular body areas, and it’s known as hyperhidrosis disorder, whereas idiopathic hyperhidrosis is extreme sweating without clear medical reasons. Stress, caffeine, spicy foods, and diet are all associated with causing night sweats in men.

Secondary hyperhidrosis usually has underlying causes such as medical conditions or maybe medication-induced. If you suffer hyperhidrosis, you sweating through your clothing, notice the sweat on your palms, feet, underarms, or face, sweating on both sides of your body, sweating at night, and also sweat in one or more areas.

6.Low Testosterone

You might experience night sweats if your levels of testosterone are low. As you get older, your body produces less testosterone naturally, but other factors like medications, injury, substance misuse, and health conditions may also decrease the amount of testosterone being produced.

Muscle weakness, reduction in bone mass, fatigue, trouble focusing or remembering things, less interest in sex, and mood changes are other symptoms associated with low testosterone.


In men, night sweats sometimes is an indicator of sleep apnea condition. A person tends to stop breathing when you are sleeping if you suffer from this condition. It can happen several in a single night, and you may be unaware anything happened if you do sleep lonely or separately with your partner.

As your body is not getting enough oxygen, it slips into the ‘fight or flight mode, which in turn triggers sweating, and it is frequent in men, with about 25% of men having this condition.

Sleep apnea develops when a stroke or any other health condition affects the central nervous system’s ability to function properly or when tissue in your throat blocks your airway (obstructive sleep apnea).

8.Changes In Temperature

Night sweats in other men occur from the normal body temperature changes that occur in their sleep cycle. Before we wake up, the body’s core temperatures tend to rise and decrease at night before we sleep. Excessive beddings, memory foam mattresses, and hot bedrooms can all contribute to very normal sweating reasons.


Night sweats tend to be early symptoms of some cancers. One of the major types of cancer associated with night sweats is lymphoma. Lymphoma is known to start in parts of your body’s immune system, such as the bone marrow, spleen, lymph nodes, and thymus.

Individuals with Hodgkin’s lymphoma experience night sweats, low fevers, and also they may be itchy, tired, and after drinking alcohol, feel pain where the tumor specifically is. On the other hand, individuals with advanced or aggressive non-Hodgkin’s lymphoma can also experience drenching night sweats.

Night sweats may also be caused by leukemia. However, individuals who have undiagnosed cancers have other signs and symptoms such as fevers and unexplained weight loss.

10. Hypoglycemia

It is known that low blood sugar or hypoglycemia can cause sweating; individuals under blood sugar-lowering medications such as oral antidiabetics and insulin may experience night sweats.

11. Gastroesophageal Reflux Disease (GERD)

GERD is connected with night sweats that occur when the muscles that keep the esophagus closed don’t function properly. This causes acid in the stomach to rise into your esophagus resulting in the burning feeling commonly known as heartburn.

You may have GERD if this happens more than once a week, and it happens during both day and night. GERD symptoms include heartburn, trouble swallowing, chest pains, regurgitation, respiratory issues, asthma symptoms, cough, and trouble sleeping.

12. Neurological Disorders

Neurologic conditions refer to those involving the nervous system- the spinal cord, the nerves, and the brain. Some neurological disorders are characterized by night sweats, such as stroke, autonomic dysreflexia, syringomyelia, and autonomic neuropathy.

Indications of neurological conditions tend to vary widely with night sweats along but immediately seek medical assistance if you notice the following:

  • Having one-sided blurry vision
  • Cannot speak or cannot speak without slurring
  • Have an extremity paralysis
  • Have severe head pain
  • Having droopiness in the lower part of your face on one side

When To Be Concerned About Male Night Sweats

If you are experiencing night sweats, you are not alone! According to the International Hyperhidrosis Society, extreme sweating during the night is fairly common. Try to address the sweating by just sleeping with fewer blankets, lowering the temperature of your bedroom, and avoiding spicy and hot drinks before bed.

If these strategies do not help and you continuously experience night sweats, you should talk to a healthcare provider. Consider visiting the doctor when night sweats:

  • Are accompanied by fever, cough, localized pain, diarrhea, and weight loss
  • Occur regularly
  • Interrupt your sleep

If you are having trouble sleeping and continuously wake up soaked in sweat or other signs and symptoms that worry you, don’t wait. Check out with your healthcare provider immediately.

Diagnosing Night Sweats In Men

A doctor must obtain a detailed medical history and order tests to determine what is causing night sweats in a person to decide whether the night sweats are due to an underlying medical condition.

Depending on the individual’s medical history and the cause of the night sweats, the tests may include specialized tests, imaging studies (CT scans or X-rays), and blood tests.

Treatment for Night Sweats In Men

Treatment of Night Sweats In Men

Generally, night sweats are a symptom of an underlying condition that requires medical treatment, but the treatment typically isn’t directed to the night sweats but rather the underlying causes.

The choice of night sweats treatment depends on the underlying cause, such as adjusting medications, hormone irregularities, and contributing factors. When night sweats arise from hormonal imbalances, a certain number of men usually find relief through bio-identical hormone replacement therapy and discuss anticholinergic substances with their healthcare provider.

Treatments consist of both prevention and management methods if there is no direct determined cause. Other at-home remedies that may help in the management of night sweats include:

  • Not eating within 2-3 hours before going to bed, avoiding caffeine, spicy foods, and alcohol, follow low sugar and a low-fat diet. Drink a lot of cold water.
  • Bed Temperature Control. Using a fan or air conditioner that will cool your bed to your ideal sleeping temperatures.
  • Sleeping Environment. Sleeping in a cool environment with breathable, light sheets and non-synthetic nightclothes. Use both ceiling and floor fans to circulate air. Set the AC thermostats at a temperature that’s conducive to sleep.
  • Using a heavy comforter or avoiding over bundling. Make your bed cool by the use of breathable materials for your pillowcases and sheets. Try also choosing lighter blankets instead of duvets or heavy comforters. Do not wear hot and uncomfortable clothing but choose breathable and lightweight fabrics for pajamas as well.
  • Getting enough daily exercise and adjusting exercise timing as physical activities just before bed may trigger sweating at night.
  • Apply a cool washcloth on your face at night before bed, or try taking a cool shower. You can also place an ice pack right under your pillow to keep cool while sleeping.
  • Practicing relaxation breathing exercises after waking with a night sweat and before bed
  • Applying a clinical strength antiperspirant to the most susceptible body parts, like the chest, underarms, feet, hands, hairline, groin, and back.

Some medications are known as anticholinergic agents that assist in the reduction of sweating, but they should only be taken under a doctor’s prescription. Night sweats may be uncomfortable, but they are benign. If you begin suspecting that they are caused by something more serious, immediately get in touch with your doctor.

Many different kinds of specialists may be consulted for this condition. An infectious disease specialist may provide treatments if night sweats are a symptom of an infectious disease. Similarly, a medical or surgical oncologist will take care of those with cancer-induced night sweats.
