If you’re late scrolling through this story on your phone, you may want to rethink your nighttime routine. As someone struggling to flip the “off” switch after work – there’s always an email to send and laundry to fold – I’m totally tempted to take revenge for postponing bedtime. However, a new study suggests that sleeping at 10:00 p.m. may be better for your overall health in the long run.
Based on data from more than 88,000 adults in the UK, the study found an association between falling asleep around 10:00 p.m. and a lower risk of heart disease. the Guardian reported. Since staying up late is also linked to alcohol consumption and other behaviors related to the risk of heart disease, we cannot say that it actually is causes Heart disease. But David Plans, a study author and senior lecturer at the University of Exeter, says that late or early bedtime regularly could affect your body’s ability to reset its internal clock, aka its circadian rhythm, every day – which it won’t has been linked only to heart disease but also to mood disorders, digestive problems, a weakened immune system, and a host of other health problems. Staying up late and sleeping late, for example, can result in missing the morning light, a crucial signal that your body relies on to regulate its circadian rhythm.
The study published today in European Heart Journal – Digital Health, involved more than 88,026 adults in the UK, 3,172 of them developed heart disease after researchers followed them for an average of about six years. According to data from devices the participants wore on their wrists for a week, the researchers found that more than 80% of those with heart disease had dozed off by 11 p.m. or later. About 15% knocked out between 10:00 PM and 10:59 PM, while about 4% did so before 10:00 PM
The researchers found that participants who nodded off between 10 p.m. and 10:59 p.m. had a lower risk of heart disease than those who slept before or after that period, the researchers said the Guardian, also after taking into account age, socio-economic status and other risk factors.
The Outlet pointed out that the study had limitations, such as the fact that most of the participants were older – between 43 and 79 years old – and knew, which makes it difficult to extrapolate the results to the general population. But until scientists do larger studies with a wider variety of participants, Plans said the Guardian that the results still substantiate the importance of good sleep hygiene.
A chronically abrupt circadian rhythm has also been linked to other health problems. Research has shown that it can increase the likelihood of digestive problems like irritable bowel syndrome (IBS) and constipation, and it can weaken your immune defenses. A 2018 study correlated more severe circadian rhythm disruption with a higher risk of major depressive disorder and bipolar disorder.
I know I sound like your parents right now. But look, I don’t make the rules. Study after study has shown that sleep is good for your health. This takes the extra step of suggesting an approximate bedtime. While plans were telling The guard that there isn’t enough data to definitely recommend going to bed at 10:00 p.m. this is a start – and probably better for you than scrolling down to sunset until dawn.
