From the point of view of traditional Chinese medicine, sedentary does not hurt the kidney, because sedentary hurts the flesh, long standing hurts the bones, long walking hurts the tendons, long lying hurts the gas, and long watching hurts the blood. Of course, meat corresponds to spleen, bone corresponds to kidney, and blood corresponds to liver, because liver stores blood. Qi corresponds to lung, muscle corresponds to liver, but bladder is sick, so the syndrome differentiation here is quite complicated. But what I want to tell you is that sedentary is definitely not good, because the five internal organs are also complementary, so you should not ignore one of the Tibetan vessels. The body also needs coordination.
