9Smoking
Smokers are often at a higher risk of developing asthma. This is because tobacco products contain thousands of harmful chemicals and toxins that can inflame and irritate your airways and lungs. Extended exposure to these components would reduce your respiratory functions and make you prone to asthma symptoms. Even those people who breathe in smoke from cigarettes would also be at risk. The best option is to quit smoking completely. Over time, your respiratory tract will improve gradually and restore the initial conditions. [9]
