A Summary of The Latest Medical News: **Long-Term Melatonin Use Linked to Higher Heart Failure Risk** A new study presented at the American Heart Association Scientific Sessions 2025 found that **adults who took melatonin supplements for sleep over the long term may have a significantly higher risk of developing heart failure**[1][2][3][5][9][16][17]. Melatonin is commonly used to help with insomnia, jet lag, and shift work, with an estimated 27% of American adults taking it, often without prescription[1][2]. **Key Details of the Research** Researchers analyzed electronic health records from more than 130,000 adults with chronic insomnia, comparing those who took melatonin for at least one year to matched peers who did not use melatonin[1][3][9]. Participants with pre-existing heart failure or other prescribed sleep medications were excluded to focus on new cases of heart problems linked to melatonin use[1]. **Major Findings** - **90% Higher Risk**: Chronic melatonin users had a 90% higher risk of developing heart failure within five years compared to non-users[1][3][5][9][10]. - **Hospitalizations Increased**: Those using melatonin for more than a year were almost 3.5 times as likely to be hospitalized for heart failure[1][5][7][10]. - **All-Cause Mortality**: Melatonin users were nearly twice as likely to die from any cause during the five-year study period[1][5][7][11]. **What’s Behind the Link?** This large observational study found a strong association but did **not prove that melatonin directly causes heart failure**[5][6][10]. Researchers caution that underlying health issues—like sleep apnea or other chronic conditions—might contribute both to insomnia and increased heart risks seen in melatonin users[6][10]. More research is needed to determine if **melatonin is a direct contributor** or simply a marker for people who already face greater health risks[6][10]. **Regulatory and Safety Concerns** The findings raise concerns as **melatonin supplements are largely unregulated in the U.S.**, easily available over-the-counter, and widely perceived as safe for long-term use[1][2][4]. Experts now urge caution, suggesting melatonin should only be used short-term unless advised otherwise by a medical professional[1][4]. **What Should Those Using Melatonin Do?** If you’re taking melatonin regularly, especially for periods longer than a few months, it's wise to discuss your sleep issues and overall heart health with a healthcare provider[4][6]. Non-pharmaceutical strategies for improving sleep—like good sleep hygiene, cognitive behavioral therapy, and relaxation techniques—are recommended alternatives for chronic insomnia[4]. **Final Note** While melatonin may help with short-term sleep problems, this latest research urges users and clinicians to carefully consider its safety when used extensively, especially among those at risk for cardiovascular disease[1][5][6]. The potential for increased heart failure risk calls for more studies, better labeling, and medical guidance to ensure safe usage. Help with your insurance? https://tally.so/r/n012P9
