Study: Going to bed at a different time each night increases your risk of these health problems

We all know that regularly going to bed at odd times isn’t good for your sleep health, but a new study suggests it could be worse than you think. Risk of heart disease and major blood vessels such as Heart disease Or a stroke, even if you get the seven to nine hours of sleep every night.

Previous studies have focused largely on health outcomes Sleep duration Instead of affecting a stable sleep-sleep cycle, these findings are therefore important.
The research team said in the study: “Our findings suggest that sleep consistency may be more important than adequate sleep duration in modifying the risk of major cardiovascular events. “

In the study, 72,269 people between the ages of 40 and 79 wore an activity tracker for a week to assess their sleep patterns, and none of the participants had a history of heart disease or heart disease. stroke.

Data were then aggregated to calculate a score Sleep consistency index For each participant, those with a score above 87 were considered to have a regular sleep pattern, those with scores below 72 were classified as having an irregular sleep pattern, and those with scores between 87 and 72 had classified as “regular.” to some extent.

The research team then collected data on the incidence of stroke, heart failure, and heart attack over the next eight years, and found that people who slept irregularly were 26% more likely to have a major cardiovascular event. than those who went to bed at about the next eight years. once every night.

Participants who had a relatively regular sleep schedule were 8% more likely to experience this type of life-threatening event

The study also showed that people with a regular sleep schedule were more likely to achieve the recommended hours of sleep each night – that’s seven to eight hours for those over 65 and seven to nine hours time for those aged 18 to 64.

In addition, the researchers found that trying to make up for lost sleep did not counteract cardiovascular risks in people who slept irregularly.
Research suggests that there is a strong link between not going to bed at the same time every night and the risk of heart disease or stroke.

The results of the study suggest that more attention should be paid to the regularity of sleep in public health management and clinical practice because of its possible role in cardiovascular health.
