| Re: Melatonin question
Melatonin is produced in the pineal gland, that is found in the brain. There is evidence that shows that its production is stimulated by darkness. That would mean that it is part of a normal circadian rhythm cycle (wake in the day and sleeping at night.)
It is a common misconseption that melatonin is a "sleeping pill" but that is not the case. Melatonin is more of a sleep aid, it does two things. First it helps regulate and maintain the body's circadian rhythm thus why it is very helpfull for jet lag. Secondly it is helps slow the mind and body down to allow for a more restful sleep, meaning on nights when you have a million thoughts running though you mind and can not sleep melatonin can help "clear" your thoughts.
It should be noted that sleepiness is a side effect that some but not all people experience, and that is more of a result of the person being more relaxed. As far of the body stopping producing melatonin with long term us of the hormone there have not been any test done that have proven this, thus far it is only speculation.
As far as effecting your allergies...I have not read any thing that even hinted at this so I do not know what to say there. You might want to make sure that it is melatonin that is causing it, because it is a hormone that is found in every living thing, from fungus to human, it would be like being allergic to blood.
