Track your night sweats
Waking up drenching in sweat is a significant medical symptom that should be tracked alongside temperature and medications. It can indicate hormonal shifts, infection, or medication side effects.
Why track this symptom?
- Monitor the frequency and severity of sweating episodes.
- Identify if they are related to your menstrual cycle or specific medications.
- Build a reliable thermal history to share with your primary care provider.

Common causes
Hormonal fluctuations, particularly during menopause, perimenopause, or thyroid disorders, are leading causes of night sweats. Medications including antidepressants, hormone therapies, and fever-reducing drugs commonly trigger excessive nighttime sweating. Infections, both acute (like flu) and chronic conditions, often present with night sweats as the body fights illness. Anxiety, stress, and panic disorders can also cause intense sweating episodes during sleep, while alcohol consumption and spicy foods before bed are frequent triggers.
When to see a doctor
Seek immediate medical attention if night sweats are accompanied by fever, unexplained weight loss, swollen lymph nodes, or persistent cough. Get urgent evaluation if sweats started suddenly after beginning a new medication or if they're severe enough to require changing sheets nightly.
Frequently Asked Questions
What should I record about night sweats?
Log severity (damp vs. drenching), time of night, room temperature and bedding, alcohol or spicy food before bed, medications, and any associated symptoms like fever or weight loss. Track how often per week.
How does tracking night sweats help my doctor?
Night sweat patterns help your doctor distinguish between hormonal causes, infections, medication side effects, and conditions that need investigation. Frequency, severity, and associated symptoms are all diagnostically important.
When should I see a doctor about night sweats?
See a doctor if night sweats are persistent, drench your sheets regularly, are accompanied by fever, weight loss, or swollen lymph nodes, or started after beginning a new medication. Your tracking data helps prioritize the right investigations.
How can I measure the severity of night sweats accurately for my tracking log?
Use a simple scale: mild (slightly damp skin), moderate (damp pajamas but dry sheets), or severe (soaked pajamas requiring a change, wet sheets). Take photos of sweat stains on sheets or pajamas if comfortable, as visual documentation can be helpful for medical evaluation. Track how many times you need to change clothes or sheets, as this provides objective measurement of severity.
What environmental factors should I track alongside my night sweats?
Record room temperature, type of bedding and sleepwear, and any heating or cooling changes in your home. Note what you ate or drank within 4 hours of bedtime, including alcohol, caffeine, and spicy foods. Track your stress level and any significant daily events, as emotional stress often correlates with night sweats. This environmental data helps identify modifiable triggers versus medical causes.

Everything is right there, there’s widgets, it’s fast and simple and syncs! I freaking love this app!
