If you have to struggle fiercely to get out of bed on every Monday morning and still feel tired, the reason is most likely due to your habit of sleeping in bed late on weekends.
According to the recent study of experts from University of Texas Southwestern, the idea that sleeping in bed late on Saturday and Sunday will help the body regain “what is lacked” in the midweek days is just a myth. Instead of help, a few hours sleeping on weekends can make you more tired.
Explaining the causes of this phenomenon, the scientists said that your above-mentioned action would cause circadian rhythm disorder for the body. You will have to get up early on Monday morning while two days earlier circadian rhythm has changed, and the body must try to control this biological clock so that it can return to normal. This makes your body / spirit more exhausted.
Almost all people mistake that if we lack sleep on weekdays, we need to catch up on lost sleep on weekends to make up for it. The circadian rhythm (type of “dance” one time a day, for example activating the wake from the sleep mode) of our bodies is only able to adapt within the variable period of 1-2h. This means that if you just add a little sleep on the weekend, it will not have any significant effect on the next Monday. However, in case of delay getting into bed or waking up 2 hours later than normal, you will have difficulty falling asleep and waking up tiredly. This effect will increase if it accompanies with other bad habits on weekends such as excessive alcohol or checking email, chatting on the bed before sleeping.
So how should we do to make up for a week of hard work and always lack of sleep on each morning? Scientists say that our body is very great, it knows how to relax more effectively when we feel tired. The sleep will be deeper, better when we exhaust. Therefore, to recover, you just need to sleep enough 8 hours on weekends. To implement this thing effectively, you had better go to bed earlier and wake up on time compared with normal workdays instead of sleeping and getting up late. This method is effective even for people having trouble sleeping.
An interesting sideline information is that previously, researchers have also demonstrated that turning off alarm clock every morning just to have a couple of minutes to sleep can make people feel tired more than getting up at that moment. That is why to work efficiently and not feel worn-out next week, the best you should do is not staying in bed late.
