Melatonin Long-Term Use Linked to Increased Heart Failure Risk
7 months agoUS
New research presented at the American Heart Association's Scientific Sessions 2025 suggests a potential link between long-term melatonin use and an increased risk of heart failure. While melatonin is a popular over-the-counter sleep aid, this preliminary study raises concerns about its long-term cardiovascular safety.
Key Insights
•
A study of over 130,000 adults with insomnia found that those who used melatonin for a year or more had an 89% higher risk of heart failure compared to non-users.
•
Long-term melatonin users were also nearly twice as likely to die from any cause.
•
The study found that participants taking melatonin were nearly 3.5 times as likely to be hospitalized for heart failure when compared to those not taking melatonin.
•
Why this matters:: These findings challenge the common perception of melatonin as a harmless supplement and highlight the need for further research into its long-term effects on heart health. It is important to note that this study does not prove a direct cause-and-effect relationship.
In-Depth Analysis
Melatonin is a hormone naturally produced by the body to regulate the sleep-wake cycle. Synthetic versions are widely available as over-the-counter supplements to treat insomnia and jet lag. However, the long-term effects of melatonin supplementation are not well-understood. This recent study analyzed electronic health records of adults with chronic insomnia, comparing those who used melatonin long-term (over a year) with those who did not. The results indicated a significant association between long-term melatonin use and increased risk of heart failure, hospitalization, and death.
It's important to consider the limitations of this study. The study's methodology has a major limitation. Participants were not surveyed on their melatonin use. Their prescription records were used to gauge who was taking what. This means that the control group (those who did not take melatonin) may have included, for example, people in the US who took melatonin without a prescription. This means that the control group may have included individuals who took melatonin without a prescription, potentially skewing the results. The study also acknowledges the need for more prospective trials to clarify melatonin's safety profile.
How to Prepare: Individuals using melatonin for sleep should consult with their healthcare provider to discuss the potential risks and benefits of long-term use. Exploring alternative sleep hygiene practices and addressing underlying causes of insomnia may be beneficial.
Who This Affects Most: Individuals with pre-existing heart conditions or those at risk for heart failure may need to be particularly cautious about long-term melatonin use. Parents considering melatonin for their children should also consult with a pediatrician.
FAQs
•
Q: Is melatonin safe for long-term use?
Current research suggests caution with long-term use. More studies are needed to fully understand the potential risks.
•
Q: What are the symptoms of heart failure?
Symptoms include shortness of breath, fatigue, swelling in the legs and ankles, and rapid or irregular heartbeat.
•
Q: Should I stop taking melatonin immediately?
Consult with your doctor before making any changes to your medication or supplement routine.
Key Takeaways
•
Long-term melatonin use may be associated with an increased risk of heart failure and mortality.
•
This research highlights the importance of consulting with a healthcare provider before using melatonin supplements, especially for extended periods.
•
Further research is needed to confirm these findings and determine the safe duration of melatonin use.
•
Consider alternative strategies for improving sleep hygiene, such as establishing a regular sleep schedule, creating a relaxing bedtime routine, and avoiding caffeine and alcohol before bed.
