Melatonin is a hormone and has an important part in the sleep-wake cycle. Formed by the pineal gland, production of melatonin is controlled by the internal clock of the body and is affected by light. During mid to late evening when it is dark, melatonin levels increase and in the morning as the sun rises, they will decrease. The increase in melatonin would cause people to become less alert as this prepares you to sleep. Also, melatonin is present naturally in some foods such as bananas, almonds, tomatoes, ginger, sweet corn, oats, rice, barley and many seeds.
Melatonin Sleep Aids
While melatonin is a hormone that occurs naturally, there are products which provide the supplemental source of the natural and synthetic melatonin. Individuals who have difficulty falling asleep, have delayed sleep phase syndrome or DSPS or perhaps are traveling across numerous time zones and would like to minimize the effects of jet lag would want to consider the use of melatonin sleep supplement. These non-prescribed melatonin sleep aids are meant to help in regulating the internal clock of the body and can induce sleep.
It is advised that if given an option between the natural and synthetic melatonin supplement, it is best to choose the synthetic version of melatonin. Natural melatonin supplements are taken from the pineal tissue of animals and carry high risk of transmitting a viral material. Melatonin sleep aids are obtainable in the form of tablets and liquid.
All melatonin supplements must be taken only when recommended. Persons who are less than 20 years old or have immune system disorder, kidney disease, liver disease, diabetes, with history of stroke or depression must consult with their physician before the use of melatonin for sleep.
