Why do we need to sleep?

  Sleep serves multiple purposes that are essential to your brain and body. The first purpose of sleep is restoration every day; our brain accumulates metabolic waste related to its normal neural activities. While this is entirely normal, too much accumulation of this waste product has been connected to neurological disorders such as Alzheimer's disease.

So how does our brain get rid of metabolic waste?

   Recently, research has suggested that sleep plays a crucial role in cleaning out the brain each night. While we walk, some toxins can be flushed out, but researchers have found that this type of clearance during sleep is as much as two times faster than during waking hours.

   During sleep, brain cells drop down by 60%, allowing the brain's waste removal system, called the glymphatic system. This system takes out the trash more easily, and as this result, our brains are restored during sleep and wake up with a refreshed and clear mind.

Memory consolidation of sleep

Sleep is necessary for memory consolidation; this is the process of maintenance and gives strength to our long-term memories. Insufficient sleep can destroy our ability to form concrete memories and emotional memories, which means it affects our fact and figures memories.

Importances of sleep for health

And insufficient sleep increases our risk of Diabetes and heart diseases.

  All of these to say that better sleep essential for our mental and physical health.

   Sleep is essential, but how much sleep do we need? For that, researchers began the experiment by collecting 48 healthy men and women taking an average rest of 7 to 8 hours per night. Then, this researches divided these subjects into four groups. In the first group, they had to stay straight without sleeping for three days. The second group slept for four hours per night, and the third group rested for six hours per night. And the fourth group slept for eight hours per night. In this experiment, three group which has taken sleep of four, six, and eight hours. This group has to perform the sleep pattern for two weeks continuously. Throughout this experiment, the subjects were tested on their physical and mental performance.

  This experiment's final result is the group that was allowed a full eight hours of sleep displayed no cognitive decreases, and no other attention lapses during this fourteen days study. On the other hand, the group who received four and six hours of sleep steadily declined with each passing day. The four hours group did not fare much better.
