Sleep. Its such an essential part of the human way of life that we tend to overlook its importance.
Why do we sleep? What makes it so important that we spend one third of our life sleeping?
Sleep is a way for the brain to focus on passive maintenance of the body. When we are awake, our brain can only focus on the current activities that need to be addressed. When we sleep, the brain has its resources freed and can therefore use them for other vital activities such cell regeneration, healing, relaxing stressed body areas and so on.
Research has shown that sleep deprivation is extremely detrimental to health. Here is an awesome video that shows the effects of sleep deprivation on facial appearance.
An Excerpt I found from this article Bring back the 40-hour work week - Salon
Research by the US military has shown that losing just one hour of sleep per night for a week will cause a level of cognitive degradation equivalent to a .10 blood alcohol level. Worse: most people who’ve fallen into this state typically have no idea of just how impaired they are. It’s only when you look at the dramatically lower quality of their output that it shows up.
So had some good sleep lately? If not, you definitely should. There are so many benefits of getting a good night's rest. You will be more active through out the day, and will have soaring energy levels. Your body will relatively be more fit, and you will most likely be in a better mood. Your concentration levels will be better, thus decision making skills and memory skills will also be better.
Have a wonderful sleep time ;)
