Picture finishing a sprint and flopping on the grass instantly. Your legs feel wobbly and your head might spin. During hard exercise, your heart pumps fast and blood vessels in your legs widen to feed working muscles. Stop abruptly and blood can pool in your legs instead of returning to your brain. That drop in blood flow can cause dizziness or even fainting. A cool-down is the gentle landing after your workout flight.
😵 DIZZY
Blood pooling in leg muscles after a sudden stop can reduce blood flow to the brain briefly.
