Poor circulation due to heart failure, thickened arteries, weak veins, or a whole host other issues, causes more problems than most people realize. Not only does it cause annoying symptoms, like cold hands and feet, but infections clear up more slowly, muscles cramp even when they are not in use, and the skin discolors. Physiologically speaking, poor circulation leads to a decrease in oxygenation levels in the body and decreases its ability to remove toxins and waste products from the system. This means that helpful cells, like those that control infections, cannot get into tissues and perform their duties. Other cells that normally clean up after healthy functioning cannot perform their intended duties either. The ill effects are system wide and can be seen by the naked eye when they alter the health, look, and feel of the skin.
