The Secret Life Of Your Brain When You Sleep

While you sleep, seemingly unaware of your surrounding and unconscious of your body, there is a part of your body that does leave reality or stop work.Behind the closed eyes, the brain continues communicating, sending and receiving, organizing memories and carrying out essential tasks.So what exactly is the brain doing when we sleep? When you become sleepy, the brain goes into sleep mode.It gradually shifts from wakefulness to sleep, the brain's activity changes.The muscles relax, heart rate generally slows, breathing becomes more regular, and then you shift through two different stages of sleep namely: The non REM and the REM (Rapid Eye Movement). The non REMThis stage is grouped into three and it starts gradually with the TRANSITION.This is when we gradually begin to fall into sleep and can be woken easily.Sometimes people feel brief muscle twitches and sensation of falling.This is mostly seen when people fall asleep on a chair and they feel like they want to fall and jerk back to reality. The next stage is the LIGHT SLEEP.Here, the sleep becomes firm and you get more comfortable.The brain produces distinctive patterns of activities called sleep spindles and K-complexes.This stage makes up more of a typical night’s sleep.The last stage, the DEEP SLEEP.Now you are deeply asleep and will be difficult to wake up.The brains produces slow waves called Delta waves and this stage of sleep is essential for physical restoration, health and strength recovery. The REMThis is a fascinating stage of sleep.The brain activity becomes more similar to that of wakefulness.The eye move rapidly beneath the eyelid and vivid dreaming commonly occurs during REM sleep.Interestingly, while the brain actively orchestrate this, the skeletal muscles are temporarily inhibited to prevent the body from demonstrated what happens in the dream.The REM is not just about dreaming but also associated with learning, memory and emotional processing.Sleep helps the brain process and reorganize information so as a learner, you need sleep to retain what you learned.Every time while you think you’re doing nothing, your brain is quietly working behind the scenes to prepare you for another day.
