Researchers found that long-term use of melatonin, a popular sleep aid, may significantly increase the risk of heart failure. A recent study involving over 130,000 adults with chronic insomnia revealed that those who took melatonin for at least a year had about a 90% higher chance of developing heart failure compared to those who did not use the supplement. This raises important questions about the safety of melatonin, which many people consider a harmless option for improving sleep.

For individuals looking to age well, this study suggests that relying on melatonin for sleep may come with serious health risks. The findings indicate that not only were participants who used melatonin more likely to develop heart failure, but they also faced higher rates of hospitalization and mortality. Specifically, 4.6% of the melatonin group experienced heart failure compared to just 2.7% in the non-melatonin group, and the hospitalization rate for heart failure was nearly three and a half times higher among melatonin users.

However, it’s important to note that this research is observational and does not prove that melatonin directly causes heart problems. The study’s authors caution that more research is needed to fully understand the implications of long-term melatonin use on cardiovascular health. While the results are concerning, they highlight the need for further investigation into the safety of melatonin, especially for those considering it as a long-term solution for sleep issues.
