What's Happening?
A recent study presented at the American Heart Association's 2025 Scientific Sessions suggests a potential link between long-term melatonin use and an increased risk of heart failure. The study analyzed health records from nearly 131,000 adults with chronic
insomnia, comparing those who used melatonin for 12 months or more with those who did not. Findings indicated a 90% higher chance of heart failure among long-term melatonin users. Experts caution that while the study shows significant associations, it does not establish a direct cause-and-effect relationship. The study highlights the need for caution in the casual use of melatonin as a sleep aid, especially for individuals at risk of heart disease.
Why It's Important?
The findings are significant as they challenge the common perception of melatonin as a safe, natural sleep aid. With the increasing use of melatonin supplements, understanding potential health risks is crucial for public health. The study's implications are particularly relevant for older adults and those with pre-existing heart conditions, who may be more vulnerable to adverse effects. The research underscores the importance of consulting healthcare professionals before using supplements and highlights the need for further investigation into the long-term safety of melatonin.
What's Next?
The study's authors and cardiologists recommend further research to confirm these findings and explore the mechanisms behind the observed associations. Healthcare providers may need to reassess guidelines for melatonin use, particularly for individuals with or at risk for heart disease. Patients are advised to seek medical advice before using melatonin and to consider alternative treatments for insomnia, such as cognitive behavioral therapy.
