Sleep. Sleeping is associated with a state of muscle relaxation and limited perception of environmental stimuli. The purposes and mechanisms of sleep are only partially clear and the subject of substantial ongoing research.[2] Sleep is sometimes thought to help conserve energy, though this theory is not fully adequate as it only decreases metabolism by about 5–10%.[3][4] Additionally it is observed that mammals require sleep even during the hypometabolic state of hibernation, in which circumstance it is actually a net loss of energy as the animal returns from hypothermia to euthermia in order to sleep.[5] Humans may suffer from a number of sleep disorders.
These include dyssomnias (such as; insomnia, hypersomnia, and sleep apnea) and parasomnias (such as sleepwalking and REM behavior disorder; and the circadian rhythm sleep disorders).

“Early to bed and early to rise makes a man healthy, wealthy and wise” – Ben Franklin, famously “Put no trust in the benefits to accrue from early rising, as set forth by the infatuated Franklin …” – Mark Twain By Leo Babauta Recently, reader Rob asked me about my habit of waking at 4:30 a.m. each day, and asked me to write about the health benefits of rising early, which I thought was an excellent question. Unfortunately, there are none, that I know of. However, there are a ton of other great benefits. Now, let me first say that if you are a night owl, and that works for you, I think that’s great. There’s no reason to change, especially if you’re happy with it. Greet the day. How to Become an Early Riser Don’t make drastic changes.
