Worried about melatonin and your heart? Recent headlines might have you losing sleep, but before you toss out your supplements, let's dive into what the experts are really saying.
This is the core of the issue: A preliminary study has sparked concerns about the long-term use of melatonin and its potential link to heart health. But before you panic, it's crucial to understand the nuances.
Doctors have long recognized the connection between poor sleep and heart problems. But this study, like many in its early stages, can't definitively prove that melatonin is the culprit. Instead, it might be the underlying insomnia that patients were trying to address.
Dr. Pratik Sandesara, an interventional cardiologist, reassures us, "We should not raise the alarm and tell patients to stop taking all their melatonin."
So, what's the deal with melatonin? Our bodies naturally produce this hormone to regulate sleep. As evening approaches and darkness falls, melatonin levels rise, signaling to our bodies that it's time for rest. Many people take lab-produced melatonin to aid sleep, combat jet lag, or adjust to new time zones.
The new study examined international electronic health records, focusing on adults with insomnia who had a melatonin prescription, suggesting they used it for at least a year.
And this is the part most people miss... Over five years, the study found that 4.6% of chronic melatonin users developed heart failure, compared to 2.7% of insomnia patients who weren't recorded as using melatonin. The study is still awaiting peer review, meaning other experts haven't yet scrutinized the findings.
But here's where it gets controversial... The study has limitations. Melatonin is available over-the-counter in the U.S., meaning some Americans in the study might have used it without it being recorded. Also, the study didn't specify dosages.
Important note: U.S. supplements aren't subject to government approval, so ingredients can vary between brands. The researchers, from SUNY Downstate Health Sciences University, emphasize the need for further investigation.
Dr. Sandesara advises patients to discuss melatonin use with their doctors. Generally, doctors recommend it for short-term use, like for jet lag.
Dr. Clyde Yancy points out that while the study doesn't prove long-term melatonin use is dangerous, there's also no evidence to support indefinite use.
Want better sleep? Prioritize sleep hygiene! This includes making sure your room is dark. As Dr. Yancy explains, "When we expose ourselves to blue light in particular at night, we are diminishing our melatonin levels. That’s science." Sleep problems aren’t “just being sleepy and tired — they’re putting yourself at risk.”
