Night Sweats: How to Alleviate Night Sweats

Night sweats are a medical condition in which a person experiences excessive perspiration while asleep, regardless of environmental factors. Night sweats are often caused by an underlying medical condition, such as menopause, infection, or hormone imbalances, or can arise as a side effect of certain medications. Night sweats are different from sweating at night. Occasionally sweating at night is usually the result of environmental factors, like a heavy blanket, tight-fitting pajamas, or a hot bedroom. Removing the blankets, wearing looser pajamas, and using a fan to encourage air circulation can usually remedy the situation. Night sweating is typically linked to an underlying medical condition. The extreme perspiration from night sweating can permeate clothing and even bedding. Common causes of night sweats include: 1. __Hot flashes__. Hot flashes (sometimes called hot flushes) are periods when a person’s body temperature rises, leaving them feeling flushed or sweaty. When these hot flashes occur during sleep, they can cause night sweating. Some people may experience hot flashes, but they’re most common in the various stages of menopause (whether perimenopause, menopause, or postmenopause). Outside of menopausal hot flashes, they may also occur in people who are pregnant or have recently given birth, or those who experience anxiety. 2. __Infections__. Many infections—whether viral, bacterial, or fungal—include common symptoms like fever and overheating, which can cause night sweats in the infected person. 3. __Medications__. Certain medications may trigger or increase the probability of night sweats as a side effect, including antidepressants (specifically selective serotonin reuptake inhibitors or SSRIs), steroids, and over-the-counter fever reducers, like aspirin and acetaminophen. 4. __Hormone imbalances__. The hypothalamus is the body’s temperature regulator. This part of the brain also plays a vital role in your endocrine system, which controls hormone regulation. Medical conditions that affect hormones, including hyperthyroidism (hyperactive thyroid) or hypoglycemia (low blood sugar) can be linked to the prevalence of night sweating. People undergoing hormone therapy may also experience night sweating. 5. __Acid reflux__. Acid reflux, also called gastroesophageal reflux disease or GERD, is a digestive disorder in which stomach acid enters and irritates the food pipe. Acid reflux can cause night sweating or heartburn during sleep. If you’re experiencing night sweats, there are a few ways to alleviate them: 1. __Consult a professional__. Since night sweating has so many potential causes, the best way to find relief is to consult a medical professional. The Mayo Clinic recommends that you see a doctor for night sweating if your symptoms occur regularly, disrupt your sleep, or accompany other concerning symptoms like fever, weight loss, pain, or diarrhea. 2. __Limit alcohol, caffeine, and spicy foods__. Alcohol, caffeine, and spicy foods can cause your body temperature to increase dramatically, which can make you feel feverish or sweat profusely. Avoid these substances, especially two to three hours before bed, to limit their effects during sleep. 3. __Try meditation techniques__. [Meditation](https://www.masterclass.com/articles/meditation-for-sleep) can reduce your heart rate and lower your body temperature to a manageable level. Consider employing practices like breath control, muscle relaxation, and gentle stretching before bed and any time you wake up with night sweats to help alleviate the symptom. 4. __Keep your sleeping environment cool__. While a hot room or stuffy pajamas aren’t the cause of night sweats, they may exacerbate the problem, so keeping yourself cool at night can help limit the chances of triggering your night sweats. Turn down the temperature before bed; avoid tight-fitting pajamas in favor of loose, flowy ones; take a sip of cool water before bed; and opt for natural, breathable fabrics for your pajamas and sheets.
