Question

Why do we feel hungry after heavy physical activity?

Answer 1

Heavy Physical activities :

1. Increased body activity means more energy requirement and hence increased amount of oxygen required.
2. After a physical activity, we take deep breathes and inhale more oxygen.
3. As a result, more oxygen is supplied to our cells and the process of breakdown of food into energy (ATP) speeds up.
4. Due to this rapid breakdown of food we feel hungry as the body needs to meet the demand.
