Night sweats refer to excessive sweating that occurs during the night. This common condition can leave your sheets and sleepwear drenched, even though the room temperature may be comfortable.
Night sweats have several potential causes:
- Menopause is a major cause in women over 40. As estrogen levels decline during perimenopause and menopause, it can trigger hot flashes and night sweats. "We frequently help menopausal women find relief from uncomfortable night sweats," said Dr. Jane Smith of Balance Hormone Clinic.
- Infections like tuberculosis, endocarditis, and HIV can induce fever and chills leading to increased perspiration at night.
- Medications like antidepressants and diabetes medicines may list night sweats as a side effect.
- Hypoglycemia or low blood sugar can spur nighttime sweating. Eating a snack before bedtime may help stabilize glucose.
- Hormone disorders like hyperthyroidism speed up metabolism leading to excess sweating. "We offer comprehensive hormone testing and personalized treatment plans to help address night sweats related to hormonal imbalances," Dr. Smith added.
- Cancers like leukemia and lymphoma can induce drenching night sweats. See your doctor promptly if you have this symptom along with unexplained weight loss.
- Idiopathic hyperhidrosis refers to a condition causing excessive sweating without a known reason.
If night sweats are interfering with your sleep, see your doctor. They will take a detailed history and conduct appropriate testing to pinpoint the cause. Treatment depends on the underlying trigger but may include
hormone therapy, medications, counseling for
menopause or infections, avoiding certain foods, glucose monitoring, and other lifestyle changes.
