In modern life, there seem to be more and more people who are used to sitting for long periods of time: students sit in class and make reports; office workers sit at work and sit at home to rest?? However, this kind of sedentary behavior The lifestyle may seem easy, but it can cause a lot of harm to the body.
Sitting for a while can indeed relieve tension or allow people to recover after exercise; however, when we spend much more "sitting time" than "active time", it may have a negative impact on the body.
My legs are numb and swollen after sitting for too long?
First of all, because when we sit, our bodies often assume a posture that causes uneven stress on the spine. Therefore, if you are used to a sedentary lifestyle, it may cause "intervertebral disc wear" and "excessive exercise" in the long run. Use some ligaments and joints." In addition, when people sit hunched over, the chest cavity will be constricted, which will also indirectly reduce the amount of oxygen filled into the lungs and filtered into the blood.
In addition, peoples bones are surrounded by muscles, nerves and blood vessels that make up the soft tissue layer of the human body, and the action of "sitting down" is squeezing them. In fact, these delicate cells do feel stress. From this point of view, when we feel numbness and swelling in our lower limbs after sitting for a long time, it may be because the nerves and blood vessels are blocked in some parts that bear the greatest pressure, hindering nerve signals, which in turn leads to numbness in the lower limbs, and Reduce the blood flow into the lower limbs, causing edema of the lower limbs.
Sitting for too long will not burn enough fat
In addition to leg numbness and edema, a sedentary lifestyle will also affect fat burning. After all, sitting for a long time will temporarily cause "lipoprotein lipase" to lose its function, and because "lipoprotein lipase" can destroy fat in the blood in the blood vessel wall, it is difficult to follow the movement when we sit down.burn the same amount of fat.
Sitting for too long reduces concentration
Furthermore, a sedentary lifestyle can actually affect concentration. When you are stationary, there is less "blood flow" and "oxygen content entering the blood from the lungs", making it easier for concentration to decline.
Lack of exercise is a long-term harm to the body
The problems mentioned above are mostly short-term problems caused by sitting for long periods of time. However, the effects of prolonged sitting on the body are sometimes long-lasting and lasting. According to recent research, a sedentary lifestyle is linked to certain types of cancer and heart disease, as well as to diabetes and certain liver and kidney problems. In addition, researchers calculated that lack of exercise causes about 9% of the global premature death rate per year, which may affect nearly 5 million people.
