7 causes of night sweats 

Waking up in the night hot and in a sweat is one of the most unpleasant feelings. These waves of intense heat can interrupt a good night's sleep and leave you feeling sluggish the next day. So understanding what could be causing your night sweats is the first step to treating them.  
Below we've listed some of the most common causes of night sweats. It's important to note, though, that your night sweats might be caused by the hot climate you're in, too many blankets or even a mattress that retains your body heat. If that's not the case, one of these seven causes might explain why you're experiencing night sweats.
