It’s not clear from this snippet if they controlled for that sort of thing: “A secondary analysis found that those who took melatonin for over a year were almost 3.5 times as likely to be hospitalized for heart failure when compared to those not taking melatonin.”
I don’t take melatonin. And I’m not saying it’s definitely not the melatonin causing the increased risk. Always read articles about medical studies with a large dose of skepticism.























The Great Book of Amber has been giving me side eye for at least 15 years. I know it’s more than one book, but it’s definitely my mental ball and chain.
