## Lesson: Diet, Exercise & Lifestyle

Your body works best when you give it good fuel, keep it moving, and protect it from harmful substances. Food gives you energy and the building blocks to grow. Exercise keeps your heart, muscles, and mind strong. Drugs, alcohol, and tobacco damage the body instead of helping it.

*(drawing: When you exercise, your heart beats faster to pump more blood to your muscles. Doing this often makes your heart stronger.)*

**Example.** Every morning, Priya eats breakfast with fruit, wholegrain toast, and milk. This gives her energy for the whole morning. At lunch, she plays football with her friends, which makes her heart pump faster and her muscles work hard. By evening, she feels tired in a good way and sleeps well.

**Tip.** Drugs, alcohol, and tobacco might seem harmless in small amounts, but they damage organs like the lungs, liver, and brain over time. Even one cigarette narrows blood vessels and makes the heart work harder. It is best to avoid them completely.

**Recap.** A balanced diet fuels your body, regular exercise strengthens your heart and mind, and avoiding drugs, alcohol, and tobacco keeps your organs healthy.
