A new study has found that people who don't have a regular sleep schedule are at higher risk of stroke and heart attack.
The study found that irregular sleep increases the risk of stroke, heart failure and heart attack in people, regardless of whether the overall amount of sleep is sufficient or not. In general, seven to nine hours of sleep are recommended for people aged 18 to 64 and seven to eight hours for those aged 65 and over.
In the study, experts looked at the records of 72,269 people aged 40 to 79 who were part of the UK Biobank study, and none of them had a history of cardiac events, such as a heart attack. Participants wore a tracker for seven days that recorded their sleep, after which experts measured each person's Sleep Regularity Index (SRI) score.
The score was determined each day by recording the time they went to bed, the time they woke up, the length of their sleep, and the number of times they woke up during the night. French A score of 0 meant very poor irregular sleep, while 100 meant perfect sleep.
The participants were divided into three groups. Those with a score below 71.6 were classified as irregular sleepers, those with a score between 71.6 and 87.3 were classified as moderately irregular sleepers, and those with a score above 87.3 were classified as regular sleepers.
The participants were followed for eight years, during which the researchers analyzed how many people had heart attacks, strokes, and heart failure.A study published in the Journal of Epidemiology and Community Health found that those who slept irregularly had a 26% higher risk of heart attack, stroke, and heart failure than those who slept regularly, while the risk was 8% higher in the moderate sleep group.
