Night Sweats in Adults

Common Causes

• Hormonal changes like menopause — In women, shifting hormones during perimenopause or menopause may trigger hot flashes and sweats at night, per Mayo Clinic.
• Infections such as flu or tuberculosis — Research suggests infections can raise body temperature, leading to sweats, especially with illnesses like COVID-19 or TB.
• Medications like antidepressants — Certain drugs for depression, blood pressure, or pain might cause night sweats as a side effect in some adults.
• Anxiety or stress — Heightened worry can activate the body's sweat response during sleep for some people.
• Low blood sugar (hypoglycemia) — Drops in blood sugar, common in diabetes, could lead to sweating episodes at night.
