Are you struggling to get a good night's sleep and reaching for melatonin supplements? You're not alone. Millions are turning to this hormone for help, but what if I told you it could actually be making your sleep worse? A leading doctor is sounding the alarm about melatonin overuse, and the information could completely change your approach to sleep aids.
Published on November 23, 2025, this warning highlights a crucial point: melatonin isn't a magic bullet. It’s a powerful tool, but like any medication, it needs to be used correctly. If you're popping melatonin pills without understanding the nuances of timing and dosage, you might be setting yourself up for more sleepless nights, not fewer.
Dr. Kunal Sood, a respected anesthesiologist and interventional pain medicine physician, recently shared his insights on Instagram, emphasizing that "Melatonin is a timing signal, not a sedative." This is a critical distinction. Think of it like this: melatonin is more like a conductor leading an orchestra (your body's sleep-wake cycle) than a sleeping pill that forces everyone to be quiet. When used improperly, it can throw the entire orchestra out of tune.
Dr. Sood explained that incorrect timing or excessive doses can disrupt the very rhythm melatonin is intended to support. But here's where it gets controversial... Many people believe that more is better when it comes to supplements. However, with melatonin, that couldn't be further from the truth. High doses can lead to a number of unwanted side effects, and some studies even suggest it could increase wake time!
One of the most common issues Dr. Sood highlights is next-day grogginess. If you're taking melatonin too late in the evening or in too high a dose, it can extend its effects into the morning. This means your brain is still getting the "wind down" signal when it should be waking up, leaving you feeling sluggish and less alert. It's like trying to drive a car with the parking brake on – you'll get there eventually, but it'll be a slow and unpleasant ride.
Another potential side effect of high-dose melatonin is vivid dreams. While some people enjoy vivid dreams, they can also be disruptive. Dr. Sood explains that high doses can intensify REM sleep or fragment sleep cycles, leading to more frequent and easily recalled dreams. This fragmented sleep can worsen morning fatigue, defeating the purpose of taking melatonin in the first place. Essentially, you might be trading insomnia for a different kind of sleep disturbance, one filled with bizarre and potentially unsettling dreamscapes.
And this is the part most people miss... The real danger of melatonin overuse lies in its ability to disrupt your body's natural circadian rhythm. Melatonin acts as a signal to shift your internal clock, telling your body when it's time to sleep and wake up. But when you take too much, or take it at the wrong time, you can throw that clock completely out of whack. As Dr. Sood points out, doses above 1 mg are metabolized more slowly and can spill into the wrong phase of the sleep-wake cycle. Reviews of existing research actually recommend low doses because high ones increase wake time and reduce overall efficacy. It's a counterintuitive finding, but it underscores the importance of using melatonin strategically.
Furthermore, Dr. Sood raises concerns about the unpredictable dosing of over-the-counter melatonin supplements. Studies have shown that many products contain far higher doses than what's listed on the label, increasing the risk of accidental overshooting and experiencing those unpleasant side effects like grogginess and disrupted sleep. This lack of regulation in the supplement industry is a serious issue and highlights the need for consumers to be extra cautious.
So, why does less often work better when it comes to melatonin? The answer lies in its role as a timing signal. Sleep experts generally recommend starting with a very low dose – 0.5 to 1 mg – because higher doses rarely improve sleep and can actually backfire. Lower doses support sleep onset without blunting morning alertness, while higher doses are more likely to cause grogginess, vivid dreams, or clock disruption. Think of it as gently nudging your body towards sleep, rather than forcing it into submission.
Ultimately, the key takeaway is that melatonin should be used with caution and awareness. It's not a long-term solution for chronic sleep problems, and it's essential to consult with a healthcare professional to determine the underlying cause of your sleep issues.
