Dr. Yang Ziqi
Secondhand smoke refers to air pollution resulting from the mixture of smoke exhaled by smokers and smoke released from burning cigarettes. It contains at least 70 carcinogenic substances. The health hazards of secondhand smoke include:
1. Respiratory problems: Long-term exposure to secondhand smoke may lead to chronic obstructive pulmonary disease (COPD), worsening asthma symptoms, and childhood respiratory tract infections such as pneumonia and bronchitis.
2. Cardiovascular diseases: Secondhand smoke can cause coronary heart disease, increase the risk of heart attacks and strokes, and even brief exposure may lead to blood vessel damage.
3. Cancer risks: Carcinogens in secondhand smoke can cause lung cancer and other types of cancer, such as laryngeal cancer, oral cancer, and nasopharyngeal cancer.
4. Effects on children's health: In addition to affecting the respiratory system, children's exposure to secondhand smoke may impair their development, increase the risk of developing lung cancer in adulthood, and potentially lead to sudden infant death syndrome (SIDS).
To protect yourself and others, avoid smoking indoors, especially in homes and cars, to reduce the dangers of secondhand smoke.
