If you’re one of those people who don’t have time to sleep — or who are tired of waking up early with online work and study, you might want to revise your sleep routine. A new study finds that getting out of bed just an hour earlier than usual can reduce the risk of depression by 23%.
a ResearchAnd the It was carried out by scientists from the University of Colorado at Boulder and the Broad Institute, Harvard and the Massachusetts Institute of Technology (MIT), with solid results. Evidence that temporal pattern influences risk of depression. It is also among the first research conducted to determine the changes in sleep and wake times needed to bring about improvements in mental health.
The temporal pattern is what is often called the “circadian clock” – the synchronization of our circadian rhythms. Is that our brain secretes some hormones necessary for the body to function depending on exposure to sunlight, such as melatonin, which is responsible for stimulating sleep. That’s why some people are more prepared during the day and some at night: they have different time patterns.
Previous studies have shown that those who are slow to get out of bed (and get out of bed) are twice as likely to be depressed as those who get up earlier in the day, regardless of their sleep hours. “We’ve known for some time that there is a relationship between sleep schedules and mood, but the question we often hear is: How early do we need to sleep and wake up in order to actually see a benefit?s? Celine Vetter said, One of the authors of the new research.
How was the research conducted?
To get a clearer idea of all this, the scientists conducted a genetic study on 840,000 people, using data from 23 and Me, a DNA testing company, and to the biomedical database UK Biobank.
Eyas Douglas, the study’s lead author, said in a statement about the advantages of using genetic studies in cases such as which – which.
Currently, genetics can explain 12% to 42% of a person’s chronotype, and more than 340 genetic variants are known to be able to influence it.
The scientists then evaluated data from 840,000 individuals focusing on these variables. Of these, 85,000 people used sleep trackers for a week, and filled out 250,000 forms related to sleep patterns. By combining this information, the goal was Understand how genetic factors affect our sleeping and waking times.
With this information available, the researchers turned to another set of samples, which included anonymous genetic and medical information and descriptive records for depressive disorder. Then they used statistical techniques to compare the two databases.
Possible results and explanations
According to research, people who have a genetic predisposition to get up early are less likely to develop depression. Also, the earlier you grow, the lower the risk of disease. They estimated that if a person went to bed an hour earlier than their usual time, their risk of developing depression was reduced by 23 percent; If you expect to sleep for two hours, the reduction can be as high as 40%.
But of course: It’s too early to definitively say that going to bed earlier reduces your risk of depression. But the study took a step in that direction. “I think the research has shifted the weight of the evidence to support the causative effect of sleep schedules in relation to disease,” he said. Douglas.
At the moment, it’s not clear what might explain this effect, but some research suggests that getting up early causes a person to be exposed to more sunlight, which can positively affect mood. Another possible reason is that the morning is in keeping with socially defined schedules, while the “evening” crowd may constantly feel out of step with the rest of the people.
