Good sleep is critical in maintaining good brain functions. It is even considered more fundamental way to keep brain operating properly. Study suggests that sleep is indispensable for memory consolidation. This is based on the fact that important memory boosting activity takes place during the deepest stages of sleep. When person is deprived of sleep, how one can expect that brain will function normally? Brain will also be sleep deprived. This can lead to compromise of certain important abilities of person such as creativity, critical thinking skills, problem solving abilities etc. Whatever you’re doing either working, studying or trying to organize life, sleep deprivation is a way for catastrophe.

How sleep Functions

Our sleep comprise of full sleep cycle loaded with 5 stages.

Stage 1 is stage of drowsiness.

Stage 2 is phase of light sleep.

Stage 3 and 4 are considered deep sleep states.

Stage 5 is the rapid eye movement (REM) in which we see dreams and certain physiological changes occur.

It is also hypothesize that memories are strengthened during this REM stage of sleep. This also says that we experience our memories again in our dreams, leading to creation of a record of events in our mind. In spite of the legitimacy of this hypothesis, it is well-known that a lack of sleep harms our cognitive abilities.

Why is Sleep So Important for Our brain Health?

Sleep is considered to be a necessity of good life and body functioning. When you sleep, brain recall the prior day’s occurrences, prepare your memory, and generates the release of hormones modifying energy mental acuity, and the moods. To carry out this important task, brain requires a time period of 6 – 7 hours. This means you have to sleep 6-7 hours to keep the brain carrying out it’s this important function. You have noticed when you have not taken proper sleep; you feel lethargic, poor concentration, mood disturbances as well as lack of creativity, clearly explaining the need of proper sleep.

As we have just discussed that many important physiological changes occur in stage 5. Likewise stage 3 and 4 sleep i.e. deep sleep is critical too. Here brain performs functions such as hormonal regulation, physical rejuvenation and growth functions. If person has not taken it, he will be deprived of these vital processes. He will more expected to get unwell, feel miserable, gloomy and even gain a detrimental weight.

In REM sleep the brain processes and carried our functions such as important for memories and emotions, actions that are vital for learning and higher level reasoning and thought. A lack of the stage 5 REM sleep consequences in poor cognitive and social dispensation, troubles with memory, and obscurity in concentrating anything. An insufficient sleep leads to work performance paucity or poor performance.
