Evidence suggests that sleeping improves memory recall and helps regulate the metabolism in the body and reduces mental fatigue.
According to the latest research, when you sleep, the brain resets itself. It removes toxic waste byproducts which may have accumulated throughout the day. Sleeping clears your mind and maintains its normal functioning.
During sleep, your brain is less responsive to external stimuli. One may wake up from the noise but can not hold a conscious conversation while asleep. Sleep is very important for the body to rest and restore its energy. It is an important cycle of resting, restoring energy, and using it again.
Lack of sleep affects different parts of your brain. For example, the temporal lobe is associated with language processing, so lack of sleep often results in slurred speech, due to the brain’s inability to process the neuronal signal at optimum levels.
During sleep, there are enzymes that repair brain cell damage caused by free radicals. In contrast, lack of sleep does not allow our brain to function normally because of the neurotransmitters, and neurons that are unable to rest or regenerate.
The condition can worsen when people are sleep deprived for days and their neurons start to degenerate because of constantly being actively at work. The neurons get worn out without having the time to regenerate and rest. Sleep deprivation also has an impact on the behavior, mood, cognitive performance, as well motor function of the body.
