Going to sleep between 10pm and 11pm could lower risk of heart disease

The study found compared to falling asleep between 10pm and 10.59pm there was a 12% greater risk for 11pm to 11.59 pm, and a 24% increased risk for falling asleep before 10pm.

Meanwhile, there was a 25% higher risk of cardiovascular disease associated with falling asleep at midnight or later.

“The body has a 24-hour internal clock, called circadian rhythm, that helps regulate physical and mental functioning.

According to results, early or late bedtimes may be more likely to disrupt the body clock, with adverse consequences for cardiovascular health.”

Analysis by sex found the increased cardiovascular risk was stronger in women.

The study included 88,026 people in the UK Biobank study, recruited between 2006 and 2010. The average age was 61 years, with participants aged between 43 and 79 years old, with 58% women.

Researchers collected data on sleep onset and waking up time over seven days using a device worn on the wrist.

Participants completed demographic, lifestyle, health, and physical assessments and questionnaires. They were then followed up for a new diagnosis of cardiovascular disease, which was defined as a heart attack, heart failure, chronic ischaemic heart disease, stroke, and transient ischaemic attack.
