02. Sitting for a long time can easily lead to poor blood circulation. If the driver sits still for a long time, the venous return in his body will be hindered to some extent, and the anorectal vein will also expand. After a long time, hemorrhoids are easy to appear. Even if they don't suffer from hemorrhoids, many drivers will have symptoms of anal pain and even bloody stool.
03, the driver sitting for a long time will also cause lumbar discomfort, which should be the common problem of most four levels, because for a long time, the weight of the body is basically pressed on your waist, because the whole pressure distribution is not particularly uniform, so the spinal muscles of the human body will also be greatly affected, and finally spasm or edema will easily occur, causing lumbar discomfort, such as low back pain.
04. It is not alarmist that drivers are prone to cancer after sitting for a long time, because sitting for a long time will lead to the low function of immune cells in the body, so the resistance to some external pathogenic factors will naturally decrease, so they are prone to cancer. According to scientists' research, the risk of colon cancer in sedentary people is indeed higher than that of some manual workers or some people who exercise regularly.
To sum up, sitting still often does great harm to your health. For bus drivers, they can knock on their thighs or rub their thighs in their spare time. You can stand against the wall at rest, so that you can exercise your quadriceps.
