Tobacco smoke contains over 7,000 chemicals, including 69 carcinogens. When you smoke, all these substances enter the body, attacking the body’s tissues caused many serious diseases.
Tobacco causes 25 different diseases for smokers, which has many dangerous diseases such as cancer, cardiovascular disease, respiratory disease and affect reproductive health. Smoking in pregnancy causes serious impacts on the health of both mother and fetus. The main diseases caused by smoking, such as lung cancer, emphysema, hair loss, cataracts…
Passive smoking is the inhalation (also called exposure) smoke from a burning cigarette or tobacco smoke by smokers made up. Passive smoke contains thousands of chemicals, including at least 250 carcinogens or toxic substances. Passive smoking can cause many serious diseases in both adults and children.

What is Second Hand Smoke
In children, passive smoking can cause respiratory infections, asthma, middle ear infections, sudden infant death, underdeveloped lung function and increases the risk of many other diseases. The smoking is a habit of men, if often smoke in the home or in the office makes the people around are passive smokers. Passive smoking is particularly dangerous for children, because the child’s lungs are not fully developed, sensitive to irritants and toxins in tobacco smoke. Passive smoking in children can cause respiratory infections, asthma, middle ear infections, sudden infant death, underdeveloped lung function and increase the risk of many other diseases.
Sudden Infant Death Syndrome
Sudden Infant Death Syndrome is also known as the death while sleeping, which is defined as the sudden death of infants without evidence of any ill when autopsy. The rate of sudden death in children exposed to tobacco during pregnancy is higher than other children from 1.4 to 8.5 times.
Low birth weight
Infants whose mothers were exposed to tobacco smoke at birth have a lower average weight of about 200 grams of the other children.
Acute respiratory infections
Acute respiratory infections are the most common acute illnesses in childhood. The acute respiratory disease may be divided into diseases related to upper respiratory and lower respiratory tract (laryngitis, bronchitis, pneumonia). Secondhand smoke infiltrate into the airways of the lungs that can cause acute respiratory disease and more severe disease due to increased edema and pneumonia.
Overall, the risks of acute respiratory diseases exacerbate higher in children with father or mother or both are smokers or have one person in the family smoke. The risk of acute respiratory diseases also increases with exposure to secondhand smoke.
Ear infections and tonsils
The evidence is sufficient to prove a cause and effect relationship between secondhand smoke among children and middle ear disease, including recurrent, acute and chronic middle ear infection. The incidence of recurrent and chronic otitis media in children have regular contact with passive smoking are higher than those not exposed to tobacco smoke were 1.3 times (for otitis recurrence) and 1.4 times (for otitis recurrence). Ear infections can lead to hearing loss.
The symptoms of asthma
Asthma is a chronic respiratory form is described as swelling of the airways, partially obstructing the airway, causing frequent wheezing and breathlessness. If your child has asthma, the passive smoking of cigarette smoke will make the disease more severe and more frequent relapses. Passive smokers increase 30% of cases of asthma in children and increase the incidence of symptoms such as cough, wheezing, phlegm, shortness of breath in children of school age to about 30%.
In addition, passive smoking also affects lung function growth. Mothers smoked during pregnancy were shown to affect children’s lung function. Synthetic study results showed that passive smoking children decreased 4.8% mid-term exhalation rate and 4.3% final exhalation rate.
