Furthermore, there is another aspect of healthy living that should be considered along with it´s benefits, and that is one we usually take for granted, sleeping well; for the most part we all consider sleep as a good thing to do , but we don’t really know how this activity benefits us; for one sleeping helps you repair your body, while we are asleep our body produces extra molecules that help mend the body so that the damage we suffer during the day from things such as stress , pollutants, sun exposure and so on, is repaired while we are off to dreamland. In addition, sleep helps to improve our memory; namely, when people do not have enough sleep, they cannot concentrate well the next day and have problems forming memories, researchers believe that during sleep, neurons can shut down and repair any damage done during the day. So without these repairs, the neurons may not function correctly causing us to feel drowsy and unable to concentrate enough to retain information in our brain. Likewise having good sleeping habits results in reducing our levels of stress, for instance, a good night's sleep can lower blood pressure and the elevated levels of stress hormones which are a natural result of today's fast paced lifestyle, there are physical effects of stress on your body, and an increase in the aging and degeneration of organs, cells and other body parts. By reducing high levels of stress, sleep helps to reverse these effects and encourages a state of relaxation. Pretty amazing thing this sleep isn't it? And it's something most of us take for granted.
