Sleep needs differ from person to person and vary depending on age. The older you are the less sleep you need, the younger the more. Primarily due to growth.
So really do require close to 8 hours of sleep/day for optimum growth. However if youa re trying to lose weight, less sleep is probably better, because you burn more calories while awake then asleep. The problem being you also have a longer time to get hungry and eat.
If you feel tired, and don't have energy and are irritable etc.... then you need more sleep.
Sleep is also cummulative, ou can make up for lack of it on the weekends to a certain extent.
