Sweating while sleeping, often called night sweats, happens when the body produces excessive sweat during sleep, sometimes soaking clothes and bedding. It can be a normal response to factors like a warm sleep environment or heavy bedding, but it can also result from internal causes such as hormonal changes (e.g., menopause), stress, certain medications, infections, or medical conditions like thyroid issues and sleep apnea. Sweating during sleep is the body's attempt to regulate temperature but can become excessive due to these various factors.
Night sweats typically occur throughout the night and can involve sweating concentrated on areas like the neck and back. Causes include menopause, anxiety, low blood sugar, certain medications, infections, or even cancers. If night sweats are frequent, disruptive, or accompanied by other symptoms like fever or unexplained weight loss, medical consultation is advised.
To reduce sweating at night, it is helpful to keep the bedroom cool, wear lightweight, breathable sleepwear, and use moisture-wicking bedding. Avoiding alcohol before bedtime and addressing any underlying medical conditions can also help manage night sweating.
