According to a study published on November 9, 2021, the time you fall asleep has an impact on health, and more specifically on the state of your heart. Find out what time to go to bed ideally.
We are not all tired at the same time at night. Some people have a harder time falling asleep while others fall into Morpheus’ arms in 5 seconds flat. According to Ministry of Health, sleep is made up of several successive cycles (4 to 6). “A sleep cycle lasts about 90 minutes in a young adult.” That is, a young adult should sleep at least 6 hours (4 cycles). A study of November 9, 2021 conducted by the European Society of Cardiology highlights a correlation between sleep and heart health. The study even indicates what time you should go to sleep to protect your cardiovascular health. “Our results suggest the possibility of a relationship between the time of falling asleep and the risk of developing CVD, particularly in women”, explains the study.
What time should you go to bed to be healthy?
The study was carried out on 88,026 participants from a UK database. This included 51,214 (57.9%) women and 36,812 (41.6%) men, aged 43 to 79. They were equipped with an accelerometer to measure their heart rate. “From this, we examined the link between the time of falling asleep and the incidence of cardiovascular disease (…) A total of 3172 cases of cardiovascular disease were reported during an average follow-up period. 5.7 years. ” The study specifies that a “Analysis by age and sex revealed that the time to fall asleep between 10 p.m. and 10:59 p.m. was associated with the lowest incidence of cardiovascular disease. (…) It is important to note that the sensitivity analyzes found that this association with an increased risk of cardiovascular disease was stronger in women, with only onset of sleep before 10 p.m. “
Women would therefore be more prone to cardiovascular disease if they do not get enough sleep. If the link between sleep and health is established, more studies are needed to confirm the link between heart disease and bedtime.
