Night sweats, also known as nocturnal hyperhidrosis, are episodes of excessive sweating while asleep. Unlike sweating caused by external heat, night sweats occur regardless of room temperature. They frequently soak bedding and clothing, causing discomfort and disruption during sleep. Night sweats can be caused by a variety of factors, including hormonal imbalances, infections, medications, and medical conditions like menopause, hyperthyroidism, or cancer.
Diagnosis entails reviewing a patient’s medical history, performing physical examinations, and occasionally running laboratory tests. Treatment aims to address the underlying cause, which can range from lifestyle changes to medical interventions, depending on the individual’s situation.
Symptoms of Night Sweating
The symptoms of night sweats vary depending on the underlying cause.
- Unexplained weight loss: Losing weight without effort may indicate a medical condition.
- Fever: A fluctuating body temperature may accompany night sweats.
- Localized pain: Pain in specific body parts may indicate an underlying condition.
- Fatigue: Excessive tiredness or weakness can be caused by a variety of conditions, including night sweats.
- Excessive sweating during the day: This is not limited to the night; certain conditions may cause sweating throughout the day.
- Chills: Feeling cold for no apparent reason, sometimes accompanied by sweats.
- persistent cough: May indicate a respiratory infection or a condition that causes night sweats.
- Diarrhea: Ongoing digestive problems may be related to the same condition that causes night sweats.
- Unusual sensations: Such as tingling or numbness, may indicate a neurological problem.
- Skin rashes or infections: Visible changes to the skin that can indicate an underlying problem.
- Snoring and breathing problems: Conditions such as sleep apnea can cause night sweats and disrupted sleep.
- Mood changes: Night sweats can be a physical manifestation of depression, anxiety, or other mood disorders.
Treatment for Night Sweats
The treatment for night sweats is largely dependent on determining the underlying cause.
- Addressing underlying medical conditions: If night sweats are caused by infections, cancer, hormone imbalances (such as menopause or hyperthyroidism), or neurological conditions, treatment will be geared toward managing the specific illness.
- Medication adjustment: If a specific medication is found to be the cause of night sweats, a doctor may adjust the dosage or switch to another medication. This is common with antidepressants, hormone therapy drugs, and diabetes medications.
- Hormone therapy: For people experiencing menopause or andropause-related night sweats, hormone replacement therapy (HRT) may be considered to balance hormone levels, but the benefits must be balanced against the risks.
- Lifestyle and environmental changes: Making the bedroom cooler, using fans, or switching to lighter bedding can help. Wearing breathable, moisture-wicking sleepwear is also advantageous. Reducing alcohol, caffeine, and spicy foods, especially before bedtime, can help reduce night sweats.
- Stress management and relaxation techniques: Because stress and anxiety can cause night sweats, yoga, meditation, deep breathing exercises, and cognitive-behavioral therapy may be beneficial.
- Dietary changes: Include eating a healthy diet and avoiding foods that cause excessive sweating. Staying hydrated is also crucial.
- Physical activity: Engaging in regular exercise can help regulate hormones and improve overall health, potentially reducing night sweats.
- Over-the-counter remedies: Antiperspirants, dietary supplements, and herbal remedies may help some people with their symptoms. However, you should consult with a healthcare professional to ensure that they are safe and effective for your specific situation.
- Surgical options: Surgery may be considered as a last resort in severe cases of night sweats caused by specific conditions.
- Cooling techniques: Include using pillows, mats, or even a “bed fan” to help regulate body temperature while sleeping.
Causes of Night Sweating
Night sweats can be caused by a variety of conditions, ranging from mild to severe.
- Infections: Night sweats can be caused by tuberculosis, HIV/AIDS, and bacterial infections such as endocarditis (heart valve infection) or osteomyelitis (bone infection).
- Menopause: The hormonal changes associated with menopause can cause hot flashes and night sweats in women, which are known as vasomotor symptoms.
- Medications: Antidepressants, diabetes medications (if they lower blood sugar), hormone therapy drugs, and steroids can all cause night sweats as a side effect.
- Hypoglycemia: Low blood sugar levels can cause night sweats, especially in diabetics who are on insulin or other blood sugar-lowering medications.
- Hormone disorders: Disorders affecting hormone levels, such as carcinoid syndrome (associated with neuroendocrine tumors), pheochromocytoma (a rare adrenal gland tumor), and hyperthyroidism (overactive thyroid), can result in night sweats.
- Night sweats: can be caused by sleep disorders such as obstructive sleep apnea, which disrupts sleep patterns and oxygen levels.
- Cancer: Night sweats can be an early warning sign of certain cancers, most notably lymphoma. They are typically accompanied by other symptoms such as unexplained weight loss and fever.
- Neurological conditions: such as stroke and autonomic neuropathy, can cause night sweats.
- Gastroesophageal reflux disease (GERD): Although less well known, GERD can cause night sweats in addition to more common symptoms such as heartburn.
- Psychiatric conditions: Physical manifestations of anxiety, depression, and stress include night sweats.
- Alcohol, caffeine, and drug consumption: Drinking alcohol or caffeine before bedtime, as well as drug use (including withdrawal from certain drugs), can cause night sweats.
- Idiopathic Hyperhidrosis: A condition in which the body consistently produces excessive sweat without a clear medical reason.
Conclusion
Night sweats, which are characterized by excessive sweating while sleeping, can be symptoms of a variety of underlying conditions, including menopause and infections. Identifying the cause is critical for treatment, which may involve lifestyle changes, medication changes, or addressing specific medical issues. Consultation with a healthcare provider is essential for personalized management and relief.

FAQs
How many night sweats are normal?
It is not unusual to sweat at night. You may sweat a little or a lot, depending on how many blankets you use, how warm your room is, and what you eat before bed. However, if you sweat excessively and frequently wake up with wet pajamas and bedding, there may be an underlying medical problem.
What stops night sweats?
Night sweats can be avoided or lessened by taking off your blankets from your bed, switching to lighter pajamas, or opening a window in your bedroom. Using a fan or air conditioning, or finding a cooler spot to sleep, may also be helpful.
Why are night sweats a red flag?
Other hormonal changes, such as those caused by pregnancy or a thyroid disorder, can also cause night sweats. Night sweats are a symptom of several medical conditions, including cancer, spinal cord injury, chronic fatigue syndrome, and mercury poisoning.
