What is the ideal bedtime with the lowest risk of heart disease?
Heart disease, which accounts for the majority of sudden deaths, is said to have the second highest mortality rate after cancer. Regarding such heart disease, a new research result was announced that 'going to bed from 22:00 to 23:00 has the lowest risk'.

Shahram Nikbakhtian and colleagues from digital healthcare company Huma.AI have published new findings on the relationship between heart disease and bedtime. Nikbakhtian and colleagues extracted data for 88,026 people from a follow-up study conducted at UK Biobank, a long-term large-scale biobank study in the United Kingdom, to determine 'the bedtime that minimizes the risk of heart disease.' ..
A follow-up study conducted by the UK Biobank collected the results of a questionnaire on bedtime / wake-up time and demographics / lifestyle / health and physical evaluation obtained from a wristband-type accelerometer at the start of the experiment for the next 5.7 years. It is a follow-up survey of various medical conditions such as heart attack, heart failure, chronic ischemic heart disease, stroke, and transient ischemic attack. At the end of the experiment, 3172 subjects, or 3.6% of the total, developed cardiovascular disease, but the incidence was 3.82% for subjects who went to bed before 22:00 and 2.79 for those who went to bed before 22:00. %, 3.33% from 23:00 to 24:00, and 4.32% after 24:00, confirming that there is a large difference in the incidence of cardiovascular disease depending on the bedtime.
The results of this survey were significant even when various variables such as age, gender, sleep time, early rising or staying up late, smoking status, weight, presence or absence of diabetes, blood pressure, cholesterol level, and socioeconomic status were taken into consideration. matter. In addition, the effect of bedtime on cardiovascular disease was particularly pronounced in women, but the cause is unknown.
In these studies, there may be cases where 'drinking and stress increase cardiovascular disease and at the same time delay bedtime', so the results of this study proved a causal relationship between cardiovascular disease and bedtime. Not. 'The timing of bedtime is a notable potential cardiovascular risk factor, independent of other risk factors and sleep characteristics,' said Dr. David Plans of the research team. If research confirms, bedtime and basic sleep hygiene could be low-cost public health goals to reduce the risk of heart disease. '
