He is a psychologist enrolled in the stress research laboratory at the University of StockholmTobye · okastatMr. and colleagues' research team tracked 38,000 subjects in Sweden for more than 13 years and conducted research focused on weekdays and weekend sleeping hours.

Mr. Ocastert categorizes people's sleeping hours on weekdays and holidays, "group for a short sleep on weekdays and holidays" "a short sleep on weekdays, a group of long sleep on holidays," "even weekdays and holidays Group of middle-time sleep, "" group with long hours sleeping on weekdays and holidays. " In addition, the subjects were classified as "under 65 years old" or "65 years old and over", grouped according to the age of subjects, and the relationship with death risk was analyzed.

As a result of the research, "group of short sleep on a weekday or a holiday" that sleeping time is less than 5 hours continuously for one week among people under 65 years old, compared to a person sleeping for about 7 hours a week continuously, The risk of death was found to be as high as 52%. However, although we are having a little sleeping time on weekdays, we sleep for a long time on holiday and do not sleep "Weekday is a short sleep, holidays a long sleeping group", the risk of death continues for one week It seems that he stayed at the same level as "Group of middle-time sleeping on weekdays and holidays" sleeping for 7 hours. In addition, as for the group that sleeps more than 9 hours each day, "the group of long sleep on weekdays and holidays", the risk of death was high similarly to the group that continues to sleep for a short time. Sleeping time difference between weekdays and holidays tended to increase in young people in their 10s to 20s, and on average they were sleeping 7 hours on weekdays and 8.5 hours on holidays.

On the other hand, elderly people aged 65 years or older who retire in Sweden have had little difference in sleeping hours on weekdays and holidays, and it seems that there was a tendency to continue short sleep of 7 hours or less on weekdays and holidays. At the same time, there is no association between sleeping time and risk of death, and it is said that this research result agrees with the previous theory that "sleeping time required by the body decreases when elderly people older than 65 years are reduced" about.

It is pointed out that the result of this research is based on the subject's self declaration to the last, "It can not be said that it was a perfect experiment because it did not include an interview of how long it took a nap." University of ArizonaMichael GrannerAssociate professor Mr. O'Castat said, "Human beings are difficult to know the exact time of how many hours they were sleeping, there are limits to self-reported research."

According to Oakstadt's research results, he said, "Sleeping at weekends is considered to have a certain effect, but it is a provisional conclusion to the last," he says, "If you lose your sleep, weekdays sleep It is impossible to say that there is no problem even if there is a shortage. " Mr. Granner said that sleeping can not bring in the sleep that he took in weekends like a financial transaction, saying, "We can not sleep on weekends when a person who is having an unhealthy meal on week days goes to the weekend, It is something like eating a salad, and although useful to some extent for health, it certainly suffers a certain amount of damage.
