Bedtime linked with heart health:

Going to sleep between 10:00 and 11:00 pm is associated with a lower risk of developing heart disease compared to earlier or later bedtimes, according to a study published today in European Heart Journal - Digital Health, a journal of the European Society of Cardiology (ESC).1

"The body has a 24-hour internal clock, called circadian rhythm, that helps regulate physical and mental functioning," said study author Dr. David Plans of the University of Exeter, UK. "While we cannot conclude causation from our study, the results suggest that early or late bedtimes may be more likely to disrupt the body clock, with adverse consequences for cardiovascular health."

While numerous analyses have investigated the link between sleep duration and cardiovascular disease, the relationship between sleep timing and heart disease is underexplored. This study examined the association between objectively measured, rather than self-reported, sleep onset in a large sample of adults.
