Scientists at the British University of Exeter discovered that going to sleep at the same time every day reduces the risk of cardiovascular disease.
The scientific team headed by David Blanes reached these conclusions from studying data on the health status of more than 88,000 men and women, with an average age of 61 years, during the years 2006-2010. All of them underwent medical examinations and answered many questions that the researchers asked them about their lifestyle and condition. Health, genetic diseases, etc. In addition, all participants carried an electronic device on their wrist for a week, which allowed them to track their physical activity, as well as the time they went to sleep and the time they woke up.
It became clear to the researchers that over the next six years, more than three thousand participants suffered from various cardiovascular diseases - myocardial infarction, stroke, heart failure, and ischemia. The researchers analyzed the information collected to compare usual sleep time and the risk of cardiovascular disease. The researchers took factors such as age, gender, socioeconomic status, body mass index, smoking, and health status (high blood pressure, diabetes, high blood cholesterol) into account. In addition, they took into account sleep duration, regularity (i.e. whether the person goes to bed and wakes up at the same time or at different times) and chronotype (whether the person is a "lark" (goes to bed early and wakes up early) or a "night owl." He stays up at night.)
It became clear to the researchers that the ideal time to go to sleep is between 10 and 11 p.m., as it was found that people who go to sleep during this period had a very small risk of heart disease and stroke. While people who go to bed very late or very early are more susceptible to cardiovascular disease.
The researchers discovered that people who go to sleep in and after midnight are 25 percent more likely to develop cardiovascular disease compared to those who go to sleep between 10 and 11 p.m., those who go to sleep before 10 p.m. are 24 percent more likely to develop cardiovascular disease, and those who go to sleep between 11 p.m. and midnight are 24 percent more likely to develop cardiovascular disease. Night by 12 percent.
According to the professor, the period between 10 and 11 p.m. is considered a special “point” in the daily cycle at which all systems of the human body operate. Deviation from this “point”, that is, before or after it, disrupts the work of the internal biological clock, which leads to negative health consequences.
