Smoking damages almost every organ in the body, raising the risk of heart disease, stroke, lung cancer, and breathing problems. Cigarettes are packed with harmful substances, including nicotine, which causes addiction and makes quitting a challenging process. However, once you stop smoking, your body starts to heal almost immediately, improving your health and quality of life.

How to Manage Withdrawal Symptoms
- Cravings
Cravings are intense but temporary. To distract yourself, chew gum, drink water, or go for a walk.
Nicotine replacement therapy (NRT), like patches, gums, or lozenges, can help reduce cravings.
- Mood Changes and Irritability
It's common to feel irritable or anxious when you first quit smoking.
Use deep breathing, meditation, and relaxation methods to effectively reduce stress.

Nicotine withdrawal can disrupt sleep patterns.
Create a relaxing bedtime routine and avoid caffeine in the evening.

Some people gain weight after quitting due to increased appetite.
Focus on healthy snacks and regular exercise to manage weight.
