Now, the matter of sleeping late on weekends can become justified.
A study from Yonsei University in South Korea showed:
1 hour of laziness on weekends can reduce the risk of depression by about 30%;
By sleeping more than 2 hours, the risk of depression may be reduced by 48%.
No kidding, this is a study of the Eight Classics of Zheng'er, which has been published in the journal Sleep Medicine in the field of sleep.
After all, sleeping is a major event in life, and as soon as the news came out, the topic immediately became the focus of hot discussion:
So, what kind of a study is this?
Weekend sleep supplementation reduces the risk of depression
To study the relationship between "weekend sleepups" and "depression," the research team recruited 5,500 volunteers for follow-up.
These volunteers face insomnia problems to a greater or lesser extent during the working day.
In this work, the researchers included "average sleep time per week", "bedtime type (early, middle, and late)" and "social jet lag associated with depression" into the sleep-related covariates for analysis.
Among them, the "average weekly sleep time" is evaluated according to the following two questions:
On average, when do you fall asleep on weekdays and when do you wake up?
On average, when do you fall asleep on the weekend and when do you wake up?
The specific calculation formula is:
[(weekday sleep time x 5) + (weekend sleep time x 2)]/7
The "time type" is based on the intermediate sleep time of the weekend, which is corrected by the sleep debt accumulated during the working day, and the calculation method used is MSFsc.
"Social jetlag" is determined by answers to questions about sleep time and wake-up time on weekdays and freedom days.
It is estimated as the absolute value of the midpoint of sleep time between weekdays and free days.
Then, in order to further study the relationship between "sleep supplement" and "depression", the researchers regarded "sleep supplement" as an independent variable and "depression" as a dependent variable, and performed a multivariate logistic regression analysis on them.
At the same time, demographic (age and sex), lifestyle (working status, alcohol intake, education level, physical activity and smoking) and sleep-related variables (time type, social jet lag, and average sleep time per week) will be used as covariates.
The results showed that normal adults needed 8 hours of sleep per night as a criterion:
1 hour of laziness on the weekend can reduce the risk of depression by about 30%.
People who slept more than 2 hours had a 48 percent lower risk of depression.
And the "benefits" of catching up on sleep on weekends don't stop there.
Another study from South Korea also showed:
Weekend sleep supplementation is also beneficial for relieving non-alcoholic fatty liver disease.
If so, does that mean "more sleep" on the weekend, which is a good thing?
Non-also, non-also.
Sleep in moderation on weekends should also be moderate
This study concluded that weekend sleep supplements reduce the risk of depression.
But at the same time, the study also came to a conclusion:
Sleeping late for more than 2 hours increased the risk of depression by 16%!
Therefore, things must be reversed, and weekend sleep must also pay attention to a "hot weather".
For this study, most netizens expressed excitement:
Finally there was a reason to sleep late.
But having said that, many friends said that it was not that they did not want to catch up on sleep, but...
So this weekend, have you, caught up sleep?
