The Evolutionary Reasons For Sleep
“Whatever the functions of sleep are, they seem to be so important that evolution is willing to put us in that place of potential danger by losing consciousness,” said Matthew Walker, a professor at University of California, Berkeley. Despite the best efforts of many top scientists, it has proven difficult to figure out what exactly it is about sleep that makes it so essential and worth the risk, in evolutionary terms.
After all, though we now sleep safely in our beds, during the early stages of humankind’s development sleeping was a much more perilous proposition, since it entailed being in an unguarded and unconscious state. Moreover, the sleep’s importance is underlined by the fact that we spend a significant portion of our time in this state - although many currently try to avoid sleep with caffeine, energy drinks, and other methods. Unfortunately, the way that society currently places little value on regular deep sleep may explain the prevalence of insomnia and other sleep disorders, as well as the necessity for ultimately harmful sleep aids.
Obviously, sleep is a biological necessity, and it is widely believed that one of the key functions of sleep is to allow the subconscious mind to process the day’s new experiences and integrate them with previous knowledge. Furthermore, it has been determined that consistent high quality sleep does indeed boost your creativity and productivity, and that is the kind of rejuvenating sleep that comes as a result of using Speed Sleep.
