In this article, we will explore the melatonin overdose warning signs and symptoms, what causes an overdose, and how to safely use melatonin to avoid unpleasant side effects.
What is Melatonin?
Melatonin is a hormone that your brain produces to control your sleep-wake cycle, also known as your circadian rhythm. It helps regulate your body temperature, blood pressure, and hormone levels, making it easier to fall asleep and stay asleep. Melatonin supplements are synthetic versions of the natural hormone and are commonly used to treat insomnia, sleep disorders, and jet lag.
What Causes a Melatonin Overdose?
A melatonin overdose typically occurs when a person takes too much of the supplement, either accidentally or intentionally. The amount of melatonin that can be toxic varies depending on individual factors, such as age, weight, and sensitivity. Taking too much melatonin can lead to excessive sleepiness, dizziness, nausea, vomiting, and other unpleasant side effects.
