Consequences of passive smoking

Consequences of passive smoking

Cigarette smoke contains over 4000 chemicals known, of which at least 50 are carcinogenic. Besides increasing the risk of cancer, these substances can cause diseases such as asthma, heart disease and emphysema. Cigarette smoke affects both smokers and nonsmokers.
Secondhand smoke consists of involuntary inhalation of fumes by one or more smokers.
Risks faced by passive smoker are smaller than those of active smokers, but health consequences can not be ignored.

Exposure to cigarette smoke, even 8 - 20 minutes train these physical reactions:
 - Increased heart rate
 - Reduction of oxygen supply
 - Constriction of blood vessels, bringing about an increase in blood pressure and cardiac muscle effort
Thousands of non-smokers die each year from diseases caused by passive smoking.
Consequences of passive smoking
World Health Organization (WHO) reached the following conclusions:

 - Secondhand smoke is responsible for many diseases and can even lead to death of the non-smokers
 - Passive smoking causes cancer in adult nonsmokers
 - Passive smoking causes heart disease in adults, is responsible for sudden infant death syndrome, ear infections and asthma for children.
 - Tobacco smoke is the most dangerous source of indoor air pollution due to its high concentration of toxic substances exposure of young age, and the fact that the exposure time is greater than in air pollution.
 - There is no risk-free level of exposure to environmental tobacco smoke.
 - A group particularly affected by environmental tobacco smoke as children. Negative effects on children's health as pneumonia, bronchitis, cough, wheezing (wheezing), aggravation of asthma and cardiovascular disease in adulthood.
Consequences of passive smoking
Effects of passive smoking on the fetus

 - Increased risk of miscarriage, ectopic pregnancy or premature birth
 - Intrauterine growth retardation
 - Child with birth defects or low birth weight
 - Increased risk of fetal death in utero

Effects of passive smoking on children

 - Increased frequency and otitis rinofaringitelor
 - Increased risk of asthma and respiratory infections such as pneumonia and bronchitis
 - Slight but significant decrease in lung development
 - Increased risk of sudden infant death
 - In addition, children are 2 times more prone to smoke if their parents are smokers.
Consequences of passive smoking
Effects of passive smoking on adult

Exposure to cigarette smoke increases the risk of lung cancer 25%, 10% risk of heart disease. Passive smoking is a risk factor for breast cancer, cervix, thyroid, brain tumors or leukemia.
Environmental Protection Agency U.S. (EPA) estimates that the risk of developing cancer due to passive smoking is 57 times greater than the risk posed by all other pollutants in the air.
 - Myocardial infarction - risk increases by 25% for a person who has never smoked, but whose partner is a smoker
 - Lung cancer - risk increases by 25% for daily exposure to cigarette smoke
 - Stroke (CVA) - passive smoking damage arterial walls, doubling the risk of stroke
