A study questions melatonin use and heart health but don't lose sleep over it

A study questions melatonin use and heart health but don't lose sleep over it 20 mins ago Don't lose sleep over headlines linking melatonin to heart failure. That's the message after some scary-sounding reports about a preliminary study involving the sleep-related supplement. A study being presented at an American Heart Association meeting used international electronic health records to track people with prescriptions for long-term melatonin use, rather than more typical short-term use for jet lag. The study isn't the kind that can prove cause-and-effect — and doctors not involved with the work stress that too little or interrupted sleep by itself raises the risk of heart disease. Specialists advise talking to your doctor as well as getting better sleep by avoiding too much light at night.
