I think this may be a problem of changes in environment and physical fitness. Why can you usually dance to two or three o'clock? Think about what kind of environment a disco is like. If the sound wave is too strong, you will be knocked to the ground. There, every cell is excited, so you won't feel tired for a while and can happily dance to the music. But when we get to the hospital, the environment between the hospital and the disco can be described as vastly different.

Look at the signs that read "Please keep quiet" or "Please don't make loud noises" hanging on the walls everywhere in the hospital. We know that the hospital environment is very quiet, and the inpatient department is very quiet. Most of them are patients and are resting. Going to bed early is also mentioned in the doctor's orders. In such a quiet environment, people naturally become drowsy. Since you are a hospitalized patient, your physical condition is naturally relatively weak, and it is natural for you to fall asleep easily.

I am a very easily influenced person. When I was working, the company had company dormitories. When I shared the dormitory with others, if she was someone who turned off the lights and went to bed at 11 o'clock, then I would My daily routine would be affected by her, and I would go to bed at 11 o'clock every day. I was so healthy that I thought I would be a healthy person with a regular routine from now on.

But as soon as we got together during the holidays, my true colors were revealed. I was high until two or three o'clock every day. Well, I was completely influenced by my roommate. How I wish she could always influence me!

Another reason is that when the doctor prescribes medicine for you, he will add some sedative and tranquilizing medicine according to some people's physical conditions. Then you will feel very sleepy after taking the medicine. Sometimes as soon as I take the medicine I feel like I'm asleep the whole day.
