Melatonin is a hormone which is present in the body naturally, produced by the pineal gland in the brain. Melatonin can be stimulated by light and suppressed in the darkness, suggesting the importance of the hormone in regulating sleep cycles and other important bodily functions. Levels of melatonin are also known to be at their highest right before bed time, which is why many people turn to melatonin supplements at night to help them sleep.
It won’t kill you, but it’ll make your life pretty miserable.”
However, this does not mean that melatonin makes you sleep. According to Dr. Oz:
“Melatonin is a sleep and body clock regulator – NOT a sleep initiator. Melatonin works with your biological clock by telling your brain when it is time to sleep. Melatonin does not increase your sleep drive or need for sleep.”
In order to use this hormone as a medicine, it must be produced in a laboratory setting. Synthetically-produced melatonin supplements can be used to treat disorders involving the sleep cycle.
The problem is that melatonin is classified as a dietary supplement rather than a medication, and isn’t regulated.
Uses Of Melatonin
Melatonin is known to be effective in correcting sleep-related and has been found to be effective in treating sleep disorders in people who have impaired vision.
Research has also shown for melatonin to be effective in correcting some symptoms of jet lag, such as those of coordination problems and alertness, along with tiredness and daytime sleepiness. However, melatonin is not effective when it comes to shortening the period of time it takes for a jet-lagged person to fall asleep.
Side Effects Of Melatonin
The problem with melatonin lies in the lack of understanding about proper dosages. Because melatonin is is labelled a dietary supplement (rather than a drug), companies can sell supplements at any dosage they like, with varying amounts.
Of the common side effects of melatonin, irritability, sleepiness, drowsiness, fatigue, dizziness and headaches are a few.
Disorientation, confusion, coordination difficulties, sleep walking, nightmares and vivid dreams have also been noted as possible side effects of melatonin, with these melatonin side effects wearing off after the cessation of the administration.
To be fair, it has not been confirmed whether these side effects are the already existing side effects of lack of sleep or jet lag, the two main reasons for the administration of melatonin, or whether they are of the hormone itself, but researchers suspect that there is a link, especially in dosages that exceed the recommended amount.
The issue is exacerbated in some less common, but more serious side effects.
Other side effects of melatonin include gastrointestinal issues such as diarrhea, abnormal feces, stomach pain, vomiting, nausea, cramping, increased appetite or altered tastes.
Seizures
Research has shown that melatonin can lead to seizures especially in children suffering from neurological disorders severe in nature. However, other studies have concluded the exact opposite results, whereby the administration of regular suggested doses of melatonin decreased the risk of seizures. This particular possibility of melatonin side effect is still a controversy. However, it is safe to say the administration of melatonin in those with neurological disorders should be monitored closely by a professional.
Mood Changes
Another potential side effect of melatonin can be mood changes, including sadness and giddiness. Overdose of the melatonin pill can lead to hallucinations and paranoia as well.
Bleeding
Bleeding is another possible side effect of melatonin. Those individuals who have disorders which may cause bleeding should be extremely careful along with those who are on pills which may have bleeding already as side effect, when taking this hormone pill.
Cholesterol Increase
Another side effect of melatonin that has been noted is the possibility of an increase in blood pressure. Hence, it is necessary that caution is practiced in those cases where cardiovascular disease runs high and high cholesterol levels are an issue. Furthermore, abnormal heart rates have also been associated with the use of melatonin.
Pregnancy-Related Side Effects
Melatonin side effects may also involve those which can hinder the process of pregnancy. Melatonin may interfere with other hormones which can cause issues during pregnancy or cause hindrances when trying to get pregnant. Developmental problems in the fetus may be triggered in cases of high levels of melatonin existing in the body, so it is not recommended that women take melatonin while pregnant.
