How many hours of Sleep do you need to be Healthy

Let’s understand the sleeping process of our body. Why we actually need the sleep?

We need sleep because the repair process of our body cannot be done at the time of awake. At the time of sleeping our brain removes unwanted things and make it more active. However it cannot be clearly described why our body need the sleep. If you don’t take a complete sleep your brain becomes less productive. Your concentration and memory level becomes low.

I have seen often that when I don’t take complete sleep, my memory becomes low. I start forgetting name of people even whom I met often. Also a task that I was completing in few minutes earlier, takes longer time. This is short term effect of not taking proper sleep. If you decrease the hours of sleeping permanently, your bodies resistant to diseases also decrease. You can be affected with any disease easily. Also, if you won’t sleep properly chances of cardiovascular diseases increase.

What happen when you sleep?

Sleep process runs within the two cycles REM (Rapid Eye Movement) and NREM (NON Rapid Eye Movement). These cycles repeats during the sleep. Most of the sleep is NREM, around 75% time of whole sleep timing. The NREM Sleep runs in four stages. Let’s see what actually happen in these stages.

Stage 1 & Stage 2- This is time between awake and getting asleep. In this time you get a light sleep. Stress in your muscles is gone and stared taking rest. At this stage your body temperature goes down. Your awareness about the surroundings is disconnected and heart rate reduces at this stage.

Stage 3 & Stage 4- These stages are the deepest sleep stages. Your blood pressure drops and your breathing speed goes slower. In this stage repair and tissue growth starts, your muscles get more blood supply. Your brain start organising the memory, useless things are removed and important things are placed in.
