Because sitting still, the blood does not circulate, and the blood supply ability of the kidney is weak, which indirectly leads to the difficulty of the operation of the kidney, so the function of the kidney gradually deteriorates. Once the kidney problem is serious, it will inevitably increase the risk of kidney disease, and if the kidney is not good, many problems in the whole body will follow, which can be said to be extremely harmful.
Moreover, sedentary damage to the spine is irreversible. Generally, you should exercise properly for ten minutes after sitting for an hour, and never sit for hours in a row. Sedentary is easy to cause spinal lesions, especially lumbar vertebrae and coccygeal vertebrae, which are prone to bulging and protruding lesions. And if this time is not only sedentary, but also accompanied by bad cross-legged and crooked sitting posture, it will inevitably increase the burden on the spine, and over time it will suffer from diseases that are convenient for the spine.
As we all know, most of us don't exercise when sitting, which will lead to the inability of our blood vessels to flow and the poor transportation of blood. In the long run, it will bring great problems to blood vessels, cause blood vessel blockage, and then cause other diseases.
Of course, sedentary will also make us fat. Sitting is not only easy to gain a belly, but also makes us full of fat. Especially if you just eat a good meal and sit still before digestion, it is most likely to cause fat growth.
No matter from which aspect, the harm of long-term sedentary is very great. It's best to keep sitting for a while and then exercise. This combination of motion and static can make the body healthier!
