Secondhand smoke is a major cause of lung damage and heart disease. Secondhand smoke is the passive smoking of non-smokers around the smoker, which is the main reason why non-smokers can develop diseases caused by smoking.
Frequent passive smoking can have adverse and even irreversible effects on the lungs. The main diseases associated with passive smoking include chronic obstructive pulmonary disease, chronic bronchitis, pulmonary heart disease, and possibly bronchial asthma, which is characterized by coughing and phlegm.
These diseases are mainly due to the very high amount of harmful chemicals from incomplete combustion of tobacco, such as carbon monoxide, nicotine, etc., that are in the air. If you take secondhand smoke for a long time, that is, long-term passive smoking, it may induce malignant tumors in the lungs, and the chances of getting lung cancer are greatly increased, as well as having a certain impact on the heart, leading to coronary atherosclerosis and hypertension. It is recommended to stay away from second-hand smoke, cherish life, and at the same time can advise people around you to smoke as little as possible. Not only is it helpful for your own health, but it also reduces the impact on others.
