When someone injures their wrist or ankle, for instance, we’re told that we must promote circulation to that area so it can heal faster. But how exactly does the blood passing through an affected area cause it to heal? It’s just passing through in the veins. Does the blood flow stimulate the tissue, or something?
In: Biology
Blood carries the required neutrients to replenish the damaged cells. If you restrict bloodflow to the area the cells will not get the proteins and minerals it needs and will not be able to repair themselves. It does not require much to restrict the blodoflow a bit. It could be that you are putting pressure on the vains which restricts them a bit. This is similar to what happens when your limb “falls asleep”.
