People with heart disease, metabolic issues, or sleep problems often have lower levels of melatonin, the body's natural sleep hormone. This drop might be caused by aging, poor sleep cycles, or long-term inflammation, and boosting melatonin back to normal levels could potentially help slow down these health conditions.

What we have found so far suggests a connection between lower melatonin levels and heart health issues. Our current analysis shows that the evidence we have reviewed leans toward an association between reduced melatonin and cardiovascular concerns. We analyzed the available research and found that 1 studies support, 0 studies refute this link. Melatonin is the body's natural sleep hormone that helps regulate your daily rest cycle. Our review indicates that people dealing with heart disease, metabolic issues, or ongoing sleep problems often show lower amounts of this hormone [1]. The drop in melatonin might be tied to getting older, disrupted sleep schedules, or long-term inflammation in the body. When we look at what happens when levels are restored, the evidence we have reviewed leans toward the idea that bringing melatonin back to typical ranges could potentially help slow down these health conditions [1]. We want to be clear that this is a partial view. The evidence we have reviewed so far points in one direction, but we are still gathering more data to understand the full picture. We do not have enough information to say exactly how much melatonin is needed or how it interacts with other treatments. Our current analysis shows a pattern, but it is not a complete map of how melatonin affects the heart. If you are wondering about your sleep and heart health, focus on keeping a steady rest schedule and talking to a doctor about your hormone levels. Small changes to your daily routine and open conversations with a healthcare provider are the best next steps while we continue to track new findings.
