Question

why do we feel warm when we are doing work or physical activity​

Answer 1

Answer:

Your muscles demand higher amounts of oxygen while exercising, so it's important to make this oxygen more available through a warm-up activity. Faster Muscle Contraction/Relaxation — Warming up with physical activity raises your body temperature, which in turn, improves your nerve transmission and muscle metabolism.
