2. What is sleep?

THE POPULAR OPINION

It is commonly known that sleep is body's 'off-mode'. The dictionaries would say it is a state when the body is physically inactive, nervous function is minimal, and consciousness is suspended. This leads to sleep being regarded as useless waste of hours🕒 where you are basically doing nothing, and powering through with sheer will and caffeine is seen as the height of productivity.... 

...No. This practice is exceedingly detrimental to our well-being in general. In the long run, this will cause depression and a feeling of ever existing fatigue. Now, the question arises...why.

REALITY

Sleep is not simply an ''off state'' or ''an inactive state''. It is more like a complex ''reset process''. Imagine our life is like a wind up spring key toy, and sleep is when we load the key again so it can function.

When we sleep, all our day's events are processed properly, and energy is restored. This is incredibly important for proper functioning of our body and is governed by something called 'the Circadian Rhythm', which is also referred to as 'the internal clock of our body'. Messing with this 'rhythm' could knock off the schedule of the body and cause unpleasant complications and disorders. Hence, taking proper sleep is necessary.
