It's a necessity. So says the World Health Organization (WHO), which also warns against the risks of not sleeping enough.
If we don't take all the rest our bodies need, we can get gastric problems, a considerable increase in appetite, and a worrying imbalance in performance. The WHO is clear: the human body needs to recover.
The amount of sleep a person needs, depends on many factors. The World Health Organization makes recommendations on the basis of age:
New-borns - 16-18 hours a day
Pre-schoolers - 11-12 hours a day
Schoolchildren - 10 hours a day minimum
Teenagers - 9-10 hours a day
Adults and seniors - 7-8 hours a day
A study by Brigham Women's Hospital (USA) determined that the ideal time to go to bed is between 22:00 and 23:00 hours. They based their estimate on a daily routine that peaks in activity at 09:00 am and dips around 22:00 or 10 pm. If, on a day like this, we are not asleep by 23:00, our level of cortisol will not lower as much as should. It may then be difficult to fall asleep at all.
For those who find it hard to fall asleep, here are some tips for a better night's sleep. Keep in mind that these recommendations depend on the uses, customs, and hours of light at the place where we live.
