"An irregular sleep, a 26% increase in the risk of stroke and heart failure"

Even if you sleep well for 7-9 hours, the risk of such diseases increases if you don't regularly follow the time you go to bed and wake up.
A joint research team at the University of Ottawa in Canada observed and analyzed 72,269 people aged 40 to 79.
The study subjects wore activity trackers for seven days to record their sleep, and the team calculated the sleep regularity index (SRI) score for each subject.
These scores captured daily variability in bedtime, wake time, sleep time, and wake time during the night, with people given scores ranging from 0 (very irregular) to 100 (perfectly regular sleep-arousal pattern).
Participants were divided into irregular sleep groups (SRI score less than 71.6), moderately irregular sleep groups (between SRI 71.6 and 87.3), or general sleep groups (SRI score greater than 87.3). Then I tracked people for eight years.
As a result, irregular sleepers had a 26% higher risk of stroke, heart failure, or heart attack than regular sleepers. It was about 8% higher for those who slept moderately irregularly.
The researchers found that the 'SRI score is a continuous measure of the increased risk of heart attack and stroke with irregular sleep patterns," he said.
He then explained that "It is important to keep a sleep time of 7 to 9 hours, but it is also necessary to have regular sleep and wake-up time.'
The findings were recently published in the international journal 『The Journal of Epidemiology & Community Health』.
