Going to bed between 10 and 11 PM might be best for your heart, according to a new study published in the European Heart Journal – Digital Health. Researchers at the University of Exeter in the UK followed more than 88,000 adults, tracking the times they went to bed and woke up, as well as the development of cardiovascular disease, like heart attacks, heart failure, and strokes. They found that three percent of the participants developed cardiovascular disease. The risk was highest in those who went to bed after midnight. It was lowest among those who fell asleep between 10 and 11 PM, likely because it disrupts our normal circadian rhythms the least.
