Answer and Explanation: 1

There are a variety of different reasons why someone might get night sweats. Most obviously, night sweats are caused by a person being too hot when they sleep. But if that is not the case, night sweating can be indicative of another health issue. In older women, menopause often causes hot flashes that can lead to night sweats. Many bacterial infections also cause excessive sweating during the night, as would any type of infection that would cause a fever. Other conditions that might cause night sweating are low blood sugar, certain hormone disorders, medication side effects, and, more seriously, specific types of cancers like lymphoma. Finally, there is an idiopathic condition called hyperhydrosis, in which a person's body produces excessive sweat for no discernible reason.
