For years we have all been told we need a good solid eight hours of beauty sleep, right? Well, maybe we do, maybe we don't. According to a new study completed by The National Sleep Foundation, you may be getting too little, or in some cases, too much sleep!

Humans and animals need three things to survive: food, water, and oxygen. Think back to when you were a teenager, and you would argue with your parents that sleep was one of those things as well, as you slumbered till two in the afternoon! We spend up to a third of our lives asleep, but are you sleeping healthy?

A new study has shown that the amount of sleep we need changes with age. There is no perfect formula to pinpoint exactly what each human being needs as far as sleep  goes, as we are all different! Additionally stimulants such as caffeine, sugar, energy drinks, alarm clocks, and lighting effect all of us differently because we are all exposed to varying levels every day.

Take a look at the chart and find out where you are in the sleep needs category. You may be surprised to know that too much sleep is also as bad as too little sleep. For you teenagers who want to get that extra couple hours of rest, now you can show your parents you actually do need it!
