Study: Going to bed earlier than usual reduces depression by 23%

A study issued by Harvard University revealed that there is a relationship between sleep timing and mood, as it was found that sleeping one hour earlier than your usual bedtime reduces the risk of depression by 23%, according to the medical express site.

The researchers confirmed that this study, which was conducted on 840 thousand people, by researchers at the University of Colorado and Harvard, gives indications of the importance of changing the temporal pattern of people in sleep dates because it affects the risk of depression, and also plays a role in affecting mental health.

The study showed that after the pandemic, millions of people had a different sleep schedule, which affected mental health and mood changes.

Previous studies have shown that the nocturnal owl syndrome, meaning feeling restless in later times, makes its owners twice as likely to suffer from depression compared to those who wake up early, regardless of how long they sleep.

The researchers examined the data of the DNA tests of the study participants, to examine the genetic links and their relationship to early waking and sleep hours, to find that there are more than 340 genetic variables that play a role in the feeling of awakening and the desire to sleep, perhaps the most prominent of them is the so-called "clock gene" PER2, which affects the pattern Chronological person.

The researchers noted that genetics play a role in choosing sleep times, ranging from 12 to 42% of us.

The researchers based on unspecified genetic data on these variants of up to 850,000 individuals, which were equipped with wearable sleep tracking devices for seven days, to find out the extent to which genes affected sleep and wake times.

The researchers found that going to bed one hour earlier than your usual time reduces the risk of depression.
