Does walking increase blood flow?

Walking at any pace is beneficial to increase blood flow throughout the body, as it is the best way to lower your blood pressure and increase muscle contraction in the legs. As muscles contract and relax, they squeeze around the large veins in the legs, promoting healthy circulation in more stagnant areas of flow.

Does blood flow to the skin decreases during exercise?

Skin blood flow during exercise Measurements in humans report an initial decrease in skin blood flow to increase blood flow to working muscle.
