When you close your eyes and drop off to sleep, do you really know what is going on inside your body? Although you may think that you are at rest, not every part of your body is doing the same. For instance, the brain is sending out all sorts of signals, many of which are controlling the various stages of sleep you will be going through.

Melotonin is naturally produced within the body by the pineal gland, which is a small pea sized gland in the center of the brain. At night, melatonin is produced to help our bodies regulate our sleep and wake cycles. As we get older, the amount of melatonin produced by our body reduces which has led scientists to believe that this may be the reason why younger people have less of a problem sleeping than older people do.
