Going to sleep between 10pm and 11pm is associated with a lower risk of developing heart disease compared to other bedtimes, new research suggests.

The study found that compared to sleep onset from 10pm to 10.59pm, there was a 25% higher risk of cardiovascular disease brought on by dropping off at midnight or later.
