what are the effects of passive smoking
When the bottom of the air scares!
Tobacco smoke contains over 4000 chemicals including over 60 carcinogens. Extremely harmful to the smoker, it is not safe for those around him. Cardiovascular diseases, respiratory disorders, cancer risk ... Check out these hazards and the particular situation of smoking in the workplace.
Did you know that non-inhaled smoke rising from the cigarette (called secondary) contains more toxic (carbon monoxide, nitrogen oxides ...) and carcinogenic substances (tar, benzene ...) than that inhaled by the smoker ... Suffice to say that passive smoking is not without risk. The National Academy of Medicine estimates that in France, passive smoking kills each year about 3000 non-smokers!
Beyond the immediate irritation of eyes, nose and throat, passive smoking can cause or exacerbate many respiratory diseases (infections, asthmatic disease, chronic obstructive pulmonary disease ...). But that's not all, your neighbor smoking also increases your risk of being a victim of lung cancer and coronary events.
CARDIOVASCULAR RISK:
The risk of heart disease is increased by 25% in case of passive smoking in the home or at work. Relayed by the American Heart Association, the American experiment made headlines in November 2005. The ban on smoking in public places (bars, restaurants, bowling alleys ...) in a small town in Montana helped bring down the frequency More infarction of a quarter in two years! More recently, at a congress of the prestigious American Association, Prof.. Lightwood of the University of San Francisco found that the elimination of passive smoking would prevent 228,000 new cases of heart disease and 119,000 deaths the next 25 years! Another new finding, US researchers have found a link between the active and passive smoking and the development of insulin resistance, considered a state of pre-diabetes;
CANCER RISK:
Passive smoking over a long period increases the risk of lung cancer (26% if the spouse smokes). So we thought that clinical observations suggested that female nonsmokers were more frequently affected (like the left suggest the KPB survey by the College of Pulmonologists of General Hospitals), a large US study found that nonsmokers are equally affected by lung cancer regardless of their sex. Lastly, cancers of the larynx and upper aerodigestive tract, pancreas and cervix are related to smoking. The link with passive smoking and seems highly possible. Only the link with sinus cancers of the face is now established, it is doubled;
RISK DISEASE BRONCHI:
Adults with asthma are especially sensitive to tobacco smoke because their respiratory system forces them to absorb more air and therefore more polluted smoke. In addition, people with chronic bronchitis and bronchial hyperresponsiveness suffer from cigarette smoke can aggravate their condition.
We have seen that for adults, the risks are very important. But the vulnerability of children to secondhand smoke is also very worrying for several reasons, but mainly because their lungs are smaller and their immune system is less well developed than in adults. Breathing faster and with fewer defenses, they inhale a large amount of harmful chemicals for their size. But the dangers are also involved even before the birth of the child:
RISK OF SUDDEN DEATH:
The risk of sudden infant death syndrome is doubled when mothers smoke. And this risk increases with the number of smokers in the house, the number of cigarettes smoked and the exposure time. The risks of miscarriage and premature birth are also increased by passive smoking. The child may also intrauterine growth retardation and low weight at birth;
RESPIRATORY DISEASES AND RISK ENT:
Child's bronchitis risk increases by 72% if the mother smokes. In asthmatic children, passive smoking increases the intensity and frequency of crises. If parents smoke at home, the risk of recurrent ear infections has increased 48% and 38% for ear effusions.
CANCER RISK:
recent discovery has something to shudder. US researchers have found carcinogens in the urine of babies of smokers parents! According to researchers, this early exposure increase the risk of cancer in adulthood.
