Why Do I Sweat so Much in My Sleep?

Night sweats occur when your body's temperature regulation system becomes disrupted during sleep. Common causes include hormonal changes, medications, infections, and sleep disorders. Women experiencing menopause account for up to 85% of night sweat cases due to fluctuating estrogen levels. Other triggers include antidepressants, blood pressure medications, and conditions like sleep apnea or hyperthyroidism. Your sleeping environment also plays a role - room temperatures above 70°F or heavy bedding can worsen symptoms. Most night sweats resolve once underlying causes are addressed, though persistent episodes warrant medical evaluation to rule out serious conditions.
