melatonin Use Linked too Potential Heart Problems, Experts Caution
Brussels, Belgium – A recent study is raising concerns about the widespread use of melatonin, a popular over-the-counter sleep aid, suggesting a potential link to heart problems in heavy consumers. while researchers emphasize that a definitive cause-and-effect relationship hasn’t been established, the findings are prompting calls for further examination and a more cautious approach to melatonin consumption.
Melatonin’s surging popularity – readily available for self-purchase in Belgium and elsewhere – may be masking potential risks, particularly with long-term use. The study highlights the need for greater awareness surrounding the hormone’s effects, as millions rely on it to combat sleep disturbances. Experts warn that melatonin is “not harmless” and “not suitable for chronic use over months or years,” urging consumers to reconsider habitual reliance on the supplement.
The research indicates that individuals who regularly consume high doses of melatonin were more likely to experience heart issues. Dr. Gérald Kierzek of Doctissimo suggests this connection could stem from melatonin’s primary function: lowering body temperature to induce sleep. “it also induces vasodilation of peripheral arteries, which influences blood circulation and can have an effect on the heart,” he explained.This vasodilation, while aiding sleep, could potentially contribute to heart disease in individuals with pre-existing vulnerabilities.
Dr. Newell,psychiatrist and head of the sleep laboratory at CHU Brugmann,echoed these concerns,emphasizing the need for further study to fully understand the long-term cardiovascular effects of melatonin. The current findings serve as a critical reminder that even seemingly benign supplements can carry unforeseen consequences, particularly when used without medical guidance. Researchers are now advocating for extensive studies to definitively prove or disprove the link between melatonin and heart problems, and to establish safe usage guidelines.
