There is not much time to rest from Monday to Friday from 9am to 5pm, with a household full of kids who need to go to football training and piano lessons. So what are you looking forward to? The weekend, of course, because it is the time when you can get more sleep, We know that enough sleep is needed to live a long and healthy life, but a recent study suggests that prolonged sleep on the weekend can help you live longer.
Torbojorn Akerstedt, Professor and Director of the Stress Research Institute at Stockholm University and co-author of the study published in the Journal of Sleep Research CNN that he "was quite surprised by what the researchers found out when they focused on this block of time." Researchers set out to investigate what happens when people have days off and decide sleep more with these days off.
To conduct the study, the researchers looked at nearly 44,000 people in Sweden and questioned their sleep habits and followed them 13 years later. They found that people who slept about five hours or less per night, including weekends, increased their mortality rate compared to those who regularly slept for seven hours. They also found that those who had slept too much also had an increased mortality rate.
Investigating those who slept less during the week and less at weekends, researchers found that the mortality rate was almost the same as those who slept regularly for seven hours. Michael Grander, director of the Sleep and Health Research Program and an assistant professor at the Department of Psychiatry at the University of Arizona's College of Medicine – Tucson said CNN: "Most people who are considered" short sleepers "probably only have seven hours to sleep six hours or less, and they are the ones who can compensate for longer sleep periods on weekends because there is not much of a deficit Sleep is something you need to replenish regularly if you do not want to harm your health, it's a fundamental part of our biology, like breathing, it's a requirement. "
You're probably wondering what that means to you. In the past, sleep experts advised against catching up on the weekends, reported Men's Health, Sleep scientist Matthew Walker spoke NPR Long before this study was conducted, he explained to them that sleep is not like a bank: "You can not accumulate debts and pay them off at a later date, if I were to deny you sleep for a whole night, and then in a subsequent one Night, all the sleep you want, you'll never get back everything you've lost. "But this new study can now change that way of thinking. Authors from the study state that the results imply that short-term sleep during the week is not a risk factor for mortality when combined with medium or long sleep periods over the weekend Men's Health,
According to a study published on PubMedCaffeine consumption up to six hours before going to sleep can disturb your sleep. For the study, participants received 400 mg of caffeine at 0, 3 or 6 hours before bedtime. The researchers used the sleep monitor to track sleep disorders. The results showed that a moderate dose of caffeine had significant sleep disturbances 3 or 6 hours before bedtime compared to placebo.
Night Melatonin plays a vital role in the circadian rhythm of the body. If you are not familiar with what the circadian rhythm is, it is basically the body's internal clock. Against this background, a study on PubMed was published to determine if ethanol (alcohol) has the ability to inhibit nocturnal melatonin. For group B and C, the dose was increased to 0.52 g / kg, but ethanol was replaced by water. The researchers found that increasing the ethanol dose inhibited nocturnal melatonin by 20%, with the lower dose showing no effect.
