Are night sweats a symptom of COVID-19?
Your night sweats may be caused by COVID-19. It’s normal for everyone to sweat throughout the day and at night, as it’s your body’s natural way of controlling your body temperature. If you do wake up with your sheets and pajamas drenched in sweat, it may be a sign that you are infected with the coronavirus. In some cases, you may also have cold sweats at night due to COVID-19, which means you suddenly feel a chill while you’re sweating. You can also experience night sweats without a fever. 1 2

There are many other reasons you may experience night sweats. If you notice that you are sweating at night, even if it’s not too hot in your room and you didn’t use too many blankets, then it may be a sign of a medical condition, such as: 1 5
