It is now known that a large amount of sleep debt has only increased with the industrialisation of the West. In one drastic realization shift work particular night shift work was in December 2007 listed by the World Health Organization (WHO) as a "probable" cause of cancer. Therefore finding the right natural sleep aid is important. The key component of most natural remedies for insomnia is melatonin which is a hormone found in all living creatures from algae to humans at levels that vary in the daily cycle. Melatonin is a natural compound produced by the body to convey message that it is night and the body needs to rest. Melatonin is vital to producing a sleep effect on the brain. Adults who don't have enough melatonin can have trouble falling asleep as their body cannot tell the difference between night and day. Taking a supplement containing melatonin can help the body strengthen its biological clock and restore the natural sleep cycle. This is the critical bit as I have stated most herbal sleeping aids contain melatonin. The problem is that most of these natural sleep aids contain three to ten times the amount of melatonin that is actually needed. The levels of melatonin are critical to the success of any natural sleep aid. The Massachusetts Institute of Technology (MIT) undertook clinical trials which concluded large doses of melatonin proved counter productive and can actually hinder getting the right type of sleep and at the correct time.
