Previously, we were told that the ideal amount of sleep to function properly was eight hours a night. However, thanks to stress, science is saying we deserve a little more. According to the World Health Organization, the American Academy of Sleep Medicine, the Centers for Disease Control and Prevention, and the National Institutes of Health, we should be getting at least eight and half hours of sleep each night.
Back to reality: Only cats, koalas and babies need 8 hours of sleep or more, every day. The time of sleep is more important than the hours spent in bed. The best time for a restful slumber is between 9-10pm and 3-4am.
