A pressure point is one of several locations along a main artery that supplies blood to a given limb of the body. A pressure point will be tightly squeezed to block of blood flow when being aided when bleeding out of a part of the body. When the point is squeezed, blood gushing will slow and the wound can be handled before too much blood Is lost.
It depends on the person, but I know that the average cycle is about 28 days long, and it only occurs once a month, in normal situations. Hope this helps! :) Stay smart, ~Mistermistyeyed.
