We need sleep, that is a truth. But what stirs up a lot of controversy is the amount of time one needs to sleep each day.
How much sleep do you need?
It has been said by many (doctors, specialists, old people, etc.) that every person needs about 8 hours of sleep a day, but where’s the evidence? What does it guarantee? Why not 9 hours of sleep a day? Is it bad for a person to sleep more than 8 hours a day? What if that person’s body is desinged to wake up after 6 hours of sleep, or 9 hours? Would it be dangerous to forcefully alter your biological clock based solely on a suggestion?
