Legs against the wall usually have the following advantages:
1, which is beneficial to reduce inflammation and swelling of lower limbs. For example, patients with swelling of lower limbs caused by standing for a long time, or old injuries of lower limbs, can use their legs against the wall to play the role of postural drainage. That is to say, the liquid accumulated in the lower limbs returns to the human body through blood circulation, and then is discharged from the body through the kidney or skin-related path, which is beneficial to the anti-inflammatory and detumescence of the lower limbs.
2. It can relieve fatigue of lower limbs. In the process of legs leaning against the wall, a large amount of blood in the lower limbs will return, which will bring back a large amount of lactic acid produced by muscle metabolism of the lower limbs, thus alleviating muscle fatigue of the lower limbs.
3. It can increase the blood flow back to the heart, and then increase the blood supply of important organs. When the legs are against the wall, a lot of blood in the thighs and calves will flow back to the heart, and this part of the blood reserve will be supplied to other important organs, such as the brain, thus alleviating the fatigue of the brain and other parts.
