What impact does secondhand smoke have on respiratory health?

Secondhand smoke significantly impacts respiratory health, particularly because it contains a mixture of harmful chemicals that can irritate the respiratory system. Exposure to secondhand smoke can lead to respiratory irritation, manifesting in symptoms such as coughing, wheezing, and shortness of breath. Beyond immediate irritation, it is also associated with an increased risk of developing asthma, particularly in children, who are more vulnerable to the adverse effects of smoke exposure. This increased risk is attributed to the inflammatory response elicited in the lungs, which can exacerbate pre-existing conditions and make individuals more susceptible to respiratory illnesses.

This choice highlights the broader public health concern regarding secondhand smoke, emphasizing that even non-smokers, particularly children and individuals with pre-existing respiratory conditions, are at risk due to the pollutants in the environment created by tobacco smoke.
