Sleep experts believe that staying in bed for 5 minutes in winter is definitely no problem. It's cold in winter. Most people stay in bed for five minutes, which can not only give the muscles that are still in a relaxed state a buffer time to return to the natural state of tension, but also make the "resting" blood gradually "awake" and return to the normal flow rate from the slow flow. It can also adjust the mental state and make the brain gradually awake from sleep. Since college, I have been trapped in bed all day except going to the toilet. Because the university courses are not very big, sometimes there may be no classes all day, so I will go to bed at this time, because I am relatively indoors and don't like going out to play, so the greatest fun at that time is sleeping and chasing plays. Of course, when I do two things, I definitely lie in bed. Only in bed is the happiest. Especially in rainy days, I often feel that sleeping in rainy days is the best. I like it raining outside, and I'm lying at home, so I'd better prepare enough food. Ha ha ha, this life is perfect. Of course, the best time to stay in bed all day is in winter. At that time, the most eager thing was that there was no class. Of course, even if I have classes, I will skip classes occasionally, hahaha, and then stay in bed and watch TV. I began to sleep when I was sleepy, and then the days passed day by day. I'm working now, but sometimes I stick to my bed all day on weekends, but now I'm getting uncomfortable, and my waist will be a little sore if I lie down for a long time.
