Side effects
- Melatonin is the natural hormone your body secretes that helps to maintain your wake-sleep cycle (also called biological clock). The wake-sleep cycle is the process of sleep and wakefulness; in humans this averages 8 hours of nighttime sleep and 16 hours of daytime activity. Melatonin is also made synthetically and available without a prescription ...
Symptoms
- Natural secretion starts from the amino acid tryptophan, with serotonin as an intermediary, and then is released to the receptors in the brain, eye and other areas to help control the sleep and wake cycles. The half-life is short, roughly 20 to 50 minutes. It is metabolized (broken down) by the CYP-450 enzyme system in the liver and then excreted in the urine or feces. Natural melatoni…

Prevention
- Jet lag is an air travel problem that causes difficulty in sleeping, fatigue, trouble concentrating, constipation, and other symptoms. Jet lag is much more likely if you cross over several time zones, and can worsen the more time zones you cross.
Interactions
- Given enough time (usually 3 to 5 days), jet lag will usually resolve on its own, but this is not always optimal when traveling. Delayed sleep phase disorder (DSPD) most often occurs in adolescents, possibly due to reduced production and melatonin deficiency at this age. Sleep onset is delayed by 3 to 6 hours compared with conventional bedtimes (10 to 11 pm). DSPD can negat…
