Melatonin is a natural hormone produced by the pineal gland in the brain in response to lowered light conditions. The pineal gland is the connection between the neuronal networks of the visual centers in the brain and the eyes. Melatonin helps to synchronize our internal clock with the light outside. Melatonin is naturally synthesized from the amino acid L-Tryptophan (abundant in turkey meat and rice). In response to increased levels of melatonin in the blood, our body will become drowsy and lowers its temperature.
During the Summer and particularly at more Northern latitudes, people may find it difficult to fall asleep due to increased daylight. Also, people who travel frequently may develop insomnia due to a change in melatonin production.
Our bodies make less melatonin as we age. Add to that a busy lifestyle with stress and many things to worry about and you have conditions that are favorable for developing insomnia.
To reset our circadian rhythm, we can take a melatonin supplement. Melatonin can easily be synthesized and people only need a small dose between 1 and 3 mg taken right before bedtime to fall asleep. Melatonin works best when vitamin B6 levels in the body are adequate, so choose melatonin supplements that also contain vitamin B6.
Melatonin is also a powerful anti-oxidant that can decease the negative effects of free radicals just like vitamin C and E. Melatonin has also been shown to stimulate the production of leptin (appetite hormone) in the presence of insulin. The increased levels of leptin during the night, results in a lowered appetite while we’re asleep.
Research has also suggested that some children with autism spectrum disorders suffer from sleep disturbances and that when these children were given melatonin, an improvement in their sleep patterns and behavior was noted. Parents who are interested in giving their children melatonin, should always consult with their pediatrician first.
To effectively treat your insomnia, supplementation with melatonin is one of the treatments available. Although melatonin is considered safe, there are a few side effects such as slower reaction times and drowsiness. Also know that pregnant women should not take melatonin. If your insomnia is severe, there may be insomnia treatments available by prescription. Please be advised to discuss any health concerns you have with your doctor.
