Synopsis of Night Sweating

Night sweating refers to excessive perspiration during sleep, often soaking clothing or bedding. While mild sweating can result from a warm sleep environment, true night sweats occur independently of external temperature and may be linked to hormonal shifts, infections, or underlying medical conditions. They can occur occasionally or be chronic and disruptive to restful sleep.

Common causes include:

  • Hormonal fluctuations: Especially during perimenopause or menopause (hot flashes)

  • Infections: Tuberculosis, endocarditis, HIV, and other chronic infections

  • Medications: Antidepressants, hormone therapies, and blood pressure drugs

  • Hypoglycemia: Low blood sugar during the night, especially in diabetics

  • Hyperthyroidism: Increased metabolic rate causes heat and sweating

  • Stress or anxiety disorders

  • Certain cancers: Particularly lymphomas (accompanied by other symptoms like weight loss and fever)

Symptoms may include:

  • Recurrent, unexplained sweating during sleep

  • Soaked clothing or bedding

  • Accompanying chills or flushing

  • Poor sleep quality and fatigue

  • Sometimes paired with fever, weight loss, or palpitations

When to see a doctor:
Seek medical care if night sweats are persistent, drenching, or accompanied by fever, weight loss, fatigue, or other systemic symptoms. Diagnosis may include blood work, hormone panels, infectious disease screening, and imaging, depending on clinical history.

Natural remedies for Night Sweating

Sleep in a Cool, Well-Ventilated Room: Use moisture-wicking sheets and wear breathable sleepwear.

Avoid Triggers Before Bed: Spicy foods, alcohol, caffeine, and heavy meals can provoke sweating.

Practice Relaxation Techniques: Stress and anxiety can elevate body temperature.

Stay Hydrated: Supports temperature regulation and prevents dehydration from sweating.

Monitor and Record Patterns: Helps identify dietary, emotional, or hormonal triggers.
