According to new research, the best bedtime to promote better heart health is between 10 p.m. and 11 p.m. This is based on the U.K. Biobank cohort study which was published in the European Heart Journal last month. The study found that the risk of developing heart disease is up to 38 per cent higher if you go to sleep earlier than 10 p.m. or later than 11 p.m.
The researchers in the U.K. monitored the sleep and wake times of 88,026 adults over seven days. They used an accelerometer device to keep track of their heart rates. The group of researchers also monitored the participant’s cardiovascular health for over 5.7 years. During the study, 3,172 of the participants developed cardiovascular disease.
Of the people who contracted the disease, 43 per cent had a bedtime after midnight and 38 per cent had a bedtime between 11 p.m and 11:50 p.m. The study specifically found that the effect of sleep-timing was more significant in women. Dr. Melissa Lem told CTV’s Your Morning that if you wake up too late or too early, you might not see the morning light at the right time.
