Generally, people who sit at work are operating on the computer, rather than mechanically facing the computer. Their hands are always moving, and their minds are always turning. Some scientists say that mental work is actually more tiring than manual work, and the thinking of the brain needs to mobilize all the cell movements of the whole body, while manual work is only the mechanical movement of the body. You should bend down without thinking. Working long hours is also very bad for people. Sitting for a long time during the day and suddenly getting together will cause backache. There is also a place where the fingers often hold the mouse wrist hard, which will feel particularly sore, and then the fingers will feel weak.

There is also sitting for a long time without exercise, and the body will be in a sub-health state. Like some manual labor, although the body feels particularly tired, it will sweat during the labor process, which is also a detoxification process, and it is relatively healthy to sit at work. Moreover, when sitting and working, people's eyes will always stare at the computer screen. As we all know, we should use our eyes moderately. Watching the computer for a long time will hurt your eyes. Because the computer screen itself has radiation to people's eyes, and it is also very close to people's eyes, staring at the computer screen for a long time will also cause myopia. On the whole, sitting at work seems to be very tiring, especially for it personnel who face computers for a long time. There are also programmers who develop app programs. Sitting and working for a long time will make them feel very tired. Like myself, I am the kind of person who sits in the office facing the computer for a long time. I feel particularly tired after work every day. Like some manual workers, they will say, alas, why are you so tired sitting in the office with the air conditioner on? Unlike those of us who are exposed to the wind and rain outside, I can only say that the work is difficult to do.
