There are two main reasons for getting tired during sleep. 1. Body temperature and sleeping environment: Many people have a very high body temperature during sleep. As a result, sleep becomes monotonous in the middle of sleep. In addition, even if the sleeping environment is much hotter, sweating can be a problem. 2. Nightmares: There are many people who often have nightmares in their sleep. Nightmares raise our body temperature and help the body sweat. As a result, a person sleeps in the middle of sleep. As a result of the above reasons, it is normal for one to fall asleep in the middle of sleep. However, sweating is uncommon without these causes. Then it can also be considered as a sign of illness. Seek medical attention as soon as possible if you have symptoms such as sweating, fever or weight loss. This is because sleep deprivation is associated with symptoms of certain diseases such as tuberculosis , hormonal disorders , hyperthyroidism , diabetes , brain or nervous system problems, etc. Thanks
