Understand the Hidden Effects of Melatonin, Health Experts Share 9 Side Effects
Melatonin is a popular supplement among American adults – with nearly a third using it as a sleep aid. With 88 percent reporting that it helps them fall asleep faster, it’s not hard to understand the appeal. Yet, like all medications and supplements, melatonin can come with its own set of side effects. Weighing potential risks against benefits is crucial. In this article, we discuss 9 potential side effects of melatonin you need to be aware of as pointed out by health experts.
1. Daytime Drowsiness
“Some people experience daytime drowsiness while taking melatonin,” says Dr. Raj Dasgupta, a medical reviewer for NCOA and ABIM. He further explains that the sleep-inducing effects of melatonin can carry over into the next day.
“Melatonin encourages the onset of sleep, but the residual effects can linger into the next day. This can be dangerous if you operate heavy machinery or drive.”
2. Headaches
Headaches represent another potential side effect of melatonin use. Should your headaches persist, it is recommended to cease melatonin usage.
“Melatonin can cause headaches in some people, possibly due to changes in brain chemistry or interactions with other medications. This is more common with higher doses,” says Dr. Dasgupta.
3. Dizziness
While less common, dizziness remains a side effect to be aware of.
“It might be related to blood pressure fluctuations or how melatonin affects your nervous system,” Dasgupta suggests.
4. Mood Swings
Remarkably, melatonin can provoke mood swings, inducing feelings of irritability, depression, or anxiety.
“Melatonin fluctuations can affect some people’s mood, leading them to feel irritable, depressed, or anxious,” Dasgupta remarks.
5. Cognitive Impairment
Rarely, melatonin may cause cognitive impairment leading to confusion or disorientation.
“In rare cases, melatonin may cause temporary confusion or disorientation, especially in older adults,” warns Dr. Dasgupta.
6. Vivid Dreams or Nightmares
With its potent sleep-inducing properties, melatonin can lead to more vivid dreams or nightmares.
“Melatonin is a natural sleep hormone, and changes in its levels may lead to more vivid dreaming,” explains Chris Mohr, PhD, RD, a fitness and nutrition advisor.
7. Changes in Appetite
Taking melatonin can also result in changes in appetite.
“Melatonin may suppress appetite in some people or cause increased hunger in others,” advises Mohr.
8. Stomach Upset
High doses of melatonin can lead to an upset stomach, triggering symptoms such as “nausea, cramps, or heartburn,” says Mohr.
9. Interaction with Other Medications and Supplements
Taking melatonin alongside other medications or supplements can pose a risk, as there may be interactions. “Melatonin may interact with other supplements, such as St. John’s Wort or valerian root,” Mohr indicates.
As we’ve explored, melatonin’s reputation for being a natural and safe sleep aid comes with a few caveats. These are all side effects that you should be mindful of if you decide to use melatonin. Should you notice any of these symptoms, it is advised to consult with a healthcare professional. Remember, while melatonin may assist some people with their sleep challenges, practicing good sleep hygiene should be your first approach before resorting to supplements.
