On the dangers of nicotine has been said and written a lot, but smoking continues to be one of the most popular bad habits of mankind.Advertising tobacco popularize among the people, the ease of production - these are the main factors that keep "afloat" smoking, as a process.
It is a process, a ritual, a psychological action, because here there is no benefit.Thus, entering the lungs with the smoke, nicotine is absorbed into the capillaries and alveoli, where gas exchange process takes place.The next destination is the blood of a smoker, which brings it to the brain.
Research, whose aim was to find out the effect of nicotine on the human body, have shown that this substance is the most harmful effect on the respiratory, digestive, cardiovascular and nervous system.At first contact with nicotine neuron nerve aggressively react to the stimulus, for which he needed much less power (electric current), than usual - the body resisted.Subsequent contacts addictive nerve, and later the "demand" to return the st
also able to replace nicotine (briefly) the natural release of endorphins (pleasure hormones), the natural hormone production slows and eventually stops altogether.
Nicotine requires only 8 seconds to get from the alveoli into the brain.CNS (central nervous system) reacts to the poison as follows: acetylcholinergic receptors under the influence of stimulus alter the operation of all systems of the body.As a result, increased blood pressure, heart rate quickens, blood vessels in the periphery of the taper, and the brain, on the contrary, are expanding.Adrenaline occurs in blood, and together with the rising level of glucose.
body to spend on all these reactions are a certain number of energy because, not even engaging in exercise, the smoker is not gaining weight.But this is not the health benefits that exercise brings, for example.In this case, the result will likely be negative.Because of the adrenaline and endorphin release smoker feels euphoric, clearing, mood elevation, and strength.But after a maximum of half an hour, all of the above effects are attenuated, and the body requires five doses of fun.
Nicotine causes both physical and psychological dependence.
body gets used to the flow of nicotine and begin to demand it in the case of a long absence (akin to drug addiction).Upon cancellation of cigarette begins the so-called "break-up": declining performance, there are disruptions in the heart, there are depressions, accompanied by headache.But that, as they say, is only one side of the coin.If the only physical dependence, it can easily be overcome.For example, using nikotinopodobnyh preparations.
This relationship is much more complicated and harder to overcome it.Smoking, as mentioned above, a kind of ritual, a ritual, without which, subsequently, the man is extremely difficult to do.Someone smokes while waiting for transport at the bus stop, someone spends time with a cup of coffee with friends, the conversation.But you never know, everyone has their own habits.And as a habit - second nature, and then have to deal with it is very difficult and hard.
to change their habits, it is necessary to change themselves, their stereotypes, world view.This break-up is much more serious than a physical need.Medications are powerless here, you need a volitional decision.And without the consent of the smoker, it will not work without a firm intention.
Smoking harms the digestive system.But before that, the blow falls on the teeth and the mucous membrane of the mouth, nose and throat.Due to the temperature difference, tooth enamel is destroyed.Yellow color arises because the cracks formed in the deposited tobacco tar, which has a specific color in addition to odor.Dissolving in the saliva, nicotine enters the stomach, where it irritates the mucosa, and then the duodenal mucosa.This leads to pain, occurrences ulcers, gastritis.
harmful substances contained in tobacco (acid, ammonia, particulate matter, pyridine bases) irritate lung.The ammonia (ammonia) can promote afebrile bronchitis, and this, in turn, significantly increases the risk of contracting tuberculosis.It prevents gas exchange and oxygen-enriched tobacco tar, which accumulates on the walls of the mucosa.
Heart smoker per day makes to 15 thousand cuts larger than a man's heart, which does not have this addiction.This stress leads to wear of the heart muscle first, a second, elevated working mode, the heart loses that amount of oxygen which is required for a given load.Why?The vessels are narrowed, spasmatic, blood flow is hampered.The second reason - instead of oxygen carrying hemoglobin "drags" on his carbon monoxide.
All these factors lead to the fact that developing coronary heart disease, angina, heart attack.Hypertensive heart disease - a frequent guest of the smoker but this is often complicated by hypertensive crisis.This leads to a violation of cerebral circulation, and subsequently a stroke.
Such disease as occlusive disease (vascular leg defeat System) is a consequence of smoking, as in non-smokers practically does not occur.The most severe form of the disease - the appearance of gangrene.
Nicotine affects the skin, making it yellow, wrinkled.Fingers become yellowish-brown hue.There is a cough and shortness of breath.For men, smoking is fraught with impotence.
It is worth noting that smoking at school age has a direct impact on student achievement.If a student smokes, it slows down the mental and physical development.Since smoking depression is not uncommon for young people lose the desire to grow and learn something, it is more difficult to choose something for everyone.These teenagers are more "inflated" and nervous, their memory impairment observed, they are slow on the uptake.
Passive smoking is also unsafe.In this case, there is a significant risk of developing lung cancer, as well as purchase other diseases associated with the respiratory system.If a family one spouse smokes, the other 30% increased risk to acquire cancer.
Effect of nicotine on the body of a pregnant woman is fraught with all sorts of pathologies and abnormalities in the unborn child.Such mothers babies are born prematurely, there is a risk of miscarriage or fetal fading, death of a child in the first year of life.Children of smokers often lag behind in physical and mental development.
smoke or not to smoke?Of course, this is a private matter, but any rational person will choose a healthy lifestyle without cigarettes.
