Why is rest necessary after good deal of exercise or work?

ورزش یا کام کے اچھے معاہدے کے بعد آرام کیوں ضروری ہے؟

To neutralize poisons that are produced during exercise or work

To rest the tired limbs

To give rest to the brain

None of these

During intense exercise, lactic acid and other metabolic by-products accumulate in the body.

Rest helps the body recover and neutralize these substances, restoring normal function and reducing fatigue.
