Why you do not sleep overnight?
The simple definition of sleep may be that we go into a state that is unaware of the surroundings.
Humans lie down for a few hours in one place to relax their body and in the meantime, they do not feel the need to talk and see but move and breathe. Usually, we do not make any preparations for sleep or relaxation and this is included in our routine.
They all know that sleep is important for physical and mental health, but to remain healthy and fit, good sleep means timely and consistent sleep. Some people suffer from insomnia or sleep disturbances, which may have different causes. They also include mental distress, confusion and anxiety.
During sleep, our brain keeps working while the body is relaxed and its temperature drops.
How much sleep can be necessary for any human being? In this regard, experts have laid the foundation for age. Their research suggests that young children can sleep for about seventeen hours a day. Children older than them sleep about nine or ten hours a day, while the majority of adults feel the need for seven or eight hours of sleep a night. However, some people wake up less often and do not feel any complaint. Medical researchers consider seven or eight hours of sleep necessary, but for some, it is longer duration.
Experts say that sleep less than a certain duration is not good for health. Such people feel tired and uncomfortable and become irritable.
