Yes, exposure to secondhand smoke at home can definitely affect your lungs. Inhaling the smoke from a chain smoker can irritate your airways and increase the risk of lung infections, asthma, and even long-term lung damage over time. It’s important to avoid exposure as much as possible by encouraging your father to smoke outside and in well-ventilated areas. If you continue experiencing symptoms, I recommend consulting a doctor for a lung check-up to rule out any underlying issues and get appropriate care.
