Why is it important to sleep and how to do it correctly? 

Whenever you have problems with sleep - come back to this material.
I would like this material to remain a reference for insomnia, nasty days and with little sleep.
We all know how important it is to sleep; but if you also understand what happens in the body from VAT. physiological - when we do things right but also when we do them wrong - then we succeed (provably) in making correct decisions. If not today, at least tomorrow; and as many times as possible.
