Sleep and Rest

Why we need Rest...?. A most important element in a life of healtful exercise, study, and play is rest. Even when e are hard at work, we need frequent breathing spells and changes of occupation and amusement to keep one part of our muscle, or our brains, from poisoning itself. But after a time, in even the strongest and toughest of us, there comes a period when no change of occupation, no mere sitting still, will rest us, we began to feel drowsy and want to go sleep. This means partly that the fatigue poisons, in spite of fresh air in change, have piled up faster than we can burn them, so that we need sleep to restore the body.All day long we are making more carbon dioxide than the oxygen we breathe in can take care of while we sleep, the situation is reversed the oxygen is gaining on the carbon dioxide. This is way the air in our bedrooms ough to be kept especially pure and fresh. Sleeping and waking are simply parts of the great rhythm in which all life beats, a period of work followed by a period of rest.When you sleep,you are not stopping all the useful activities of your body and mind, you are simply giving some of the most useful and most important of them a chance to work.The only likeness between sleep and death is that in both the body is quite and the eyes are closed. really we are never more alive and growing than when a sleep.
If you cannot sleep well, it is a signal that something wrong with your health, a danger signal of great importance, which should be attended to at once.
