Smoking is one of the most harmful habits for your respiratory system. The lungs are designed to take in oxygen and remove carbon dioxide, but cigarette smoke damages this process from the very first puff.
Immediate Effects
- Irritates the throat and airways
- Reduces the action of cilia (tiny hairs that clear mucus)
- Causes shortness of breath and cough
Long-Term Damage
- Chronic bronchitis – constant mucus and coughing
- Emphysema – destruction of air sacs (alveoli)
- COPD – difficulty breathing in daily life
- Lung cancer – risk rises dramatically
Can the Lungs Heal?
Yes. When someone quits smoking, the lungs begin to repair themselves. Within weeks, breathing improves and the risk of disease starts to fall. The earlier a person quits, the greater the recovery.
Some Advices for You
- Don’t start: It’s much easier to avoid smoking than to quit later.
- Think ahead: Even a few cigarettes can harm your lungs over time.
- Protect your studies: Healthy lungs mean better focus, memory, and energy for school.
- Stay active: Sports and exercise are easier and more enjoyable if you avoid smoking.
- Support friends: Encourage classmates to avoid cigarettes and help each other stay healthy.
Remember: protecting your lungs today helps you live healthier and do better in school tomorrow.
