10 p.m. Bedtime May Help Your Heart Health

A recent study has found a link between going to sleep between 10 p.m. and 11 p.m. and lower rates of heart disease.

Each year, about 18.6 million people die from cardiovascular disease — which includes heart attack and stroke — making it the world's leading cause of death.

Researchers in the UK looked at data from about 88,000 people between the ages of 43 and 79 to look at how sleep may be linked to heart health.

The study participants wore devices that tracked when they went to sleep and woke up for seven days. Participants also answered questions about their health and lifestyles.

The researchers followed the study participants and their heart health for an average of almost six years. About 3.5% of the study participants developed cardiovascular disease in that time.

People who went to bed between 10 p.m. and 10:59 p.m. had the lowest rates of cardiovascular disease. Going to sleep after midnight was linked with a 25% higher risk of developing heart disease, going to sleep after 11 p.m. was linked with a 12% increase, and going to bed before 10 p.m. was linked with a 24% increase.

The study also found that the link between sleep times and increased heart disease risk was stronger among women. For men, only going to bed before 10 p.m. was linked with an increased risk of heart disease.

The researchers say that there is still more work to be done to understand how sleep affects heart health, but the study could help us reduce cardiovascular disease rates.

Questions

1.How many people die from cardiovascular disease each year?

2.How did the researchers measure participants' sleep times?

3.Was the link between sleep times and increased heart disease risk stronger among men or women?
