The number of hours of sleep necessary depends fundamentally on age, so friends steemit a great greeting from my part, here a valuable information to anyone who may be interested!
While newborns and babies stay almost all day in a kind of drowsiness, with age with age the hours of sleep are increasingly reduced ..
In the adult, the average is between 7 and 8 hours, but from 50 onwards the need decreases to 6 hours or less.
The elderly often complain that they sleep badly, sometimes, what happens is that they have not assumed the fact that over the years they need less sleep.
If you sleep five and a half or six hours are usually physiologically sufficient.
Sleeping is necessary to help us recover from daily routines, we do not recharge energies for day to day. Greetings that the information is pleasant for you!
