Waking up drenched in sweat can be frustrating and sometimes worrying. Night sweats are more common than many people think – but the reasons behind them vary widely.
What are night sweats?
Night sweats are episodes of excessive sweating during sleep that soak through clothes or bedding. They’re different from simply being too warm under a thick duvet – true night sweats happen even in a cool room.
Common causes of night sweats
- Hormonal changes: Menopause, perimenopause, pregnancy, and thyroid disorders can all trigger sweating at night.
- Infections: Viral or bacterial infections, especially those with fever, often cause temporary night sweats.
- Medications: Certain antidepressants, pain relievers, and diabetes medications may list night sweats as a side effect.
- Stress and anxiety: Emotional stress can activate the nervous system and lead to sweating during sleep.
- Medical conditions: Diabetes, sleep apnea, or more rarely, certain cancers can be associated with night sweats.
- Idiopathic hyperhidrosis: For some people, overactive sweat glands cause excessive sweating without an underlying illness.
When should you seek medical help?
Occasional night sweats are usually harmless. But if they are frequent, disrupt your sleep, or are accompanied by symptoms such as weight loss, fever, or fatigue, you should consult a doctor.
Treatments that may help
- Lifestyle adjustments: Keep your bedroom cool, use light bedding, and avoid alcohol or caffeine before bed.
- Medical evaluation: Identify and address any underlying conditions.
- Hyperhidrosis treatments: If the problem is due to overactive sweat glands, options like Botulinum toxin (BTX) injections or miraDry can reduce sweating effectively.
