Waking up in the middle of the night drenched in sweat is an uncomfortable and disruptive experience. These episodes, known as night sweats, go beyond simply feeling a bit warm. They are repeated occurrences of extreme perspiration that can soak your pajamas and sheets, forcing you to wake up and often making it difficult to fall back asleep.
While occasionally overheating is normal, persistent night sweats can be a sign of an underlying issue. This guide will cover the most common causes of night sweats, from simple lifestyle factors to hormonal changes, and provide practical tips to help you sleep cooler and more comfortably.
Common Causes of Night Sweats
There are many potential reasons you might be experiencing night sweats.
- Your Sleep Environment: This is the simplest and most common cause. A bedroom that is too hot, or bedding that isn't breathable (like synthetic fabrics), can easily trap heat and lead to sweating.
- Hormonal Changes: For women, night sweats are a classic symptom of perimenopause and menopause, caused by fluctuating estrogen levels that affect the body's temperature regulation.
- Anxiety and Stress: The body's "fight or flight" response, triggered by anxiety, can lead to sweating at any time, including at night.
- Medications: Certain medications, including some antidepressants, steroids, and drugs taken to lower fever (like aspirin), can list night sweats as a side effect.
- Alcohol and Spicy Foods: Consuming alcohol or spicy foods close to bedtime can raise your body temperature and trigger sweating.
- Underlying Medical Conditions: In some cases, night sweats can be a symptom of conditions like infections, hormone disorders (like an overactive thyroid), or, much more rarely, certain cancers. This is why persistent and severe sweats should be evaluated by a doctor.

How to Manage and Reduce Night Sweats
You can take several steps to create a cooler, more comfortable sleep experience.
- Optimize Your Bedroom Temperature: This is the first and most important step. Keep your room cool, ideally between 60-67°F (15-19°C). For more tips, see our guide to the perfect sleep environment.
- Choose Breathable Bedding: Opt for natural, breathable fabrics like cotton, linen, or bamboo for your sheets and pajamas. Consider a cooling mattress or mattress topper designed to draw heat away from the body.
- Practice Stress Management: Incorporate a relaxing bedtime routine with activities like meditation, deep breathing, or journaling to calm your nervous system before sleep.
- Avoid Triggers: Try to avoid alcohol, caffeine, and spicy foods in the hours leading up to bedtime.
- Keep Water by Your Bed: If you do wake up sweaty, have a glass of cool water on your nightstand to rehydrate.
By addressing these factors, you can often significantly reduce the frequency and severity of night sweats. If your symptoms persist or worry you, don't hesitate to seek medical advice.
