Smoking harms your health

For a long time, people have been trying to learn how to manage their mood, stimulate working capacity, take measures to help calm down … Many people consider tobacco smoking to be one of such means.

The fact is that the nicotine alkaloid contained in tobacco has a two-phase effect on the nervous system, causing its short excitation, which is quickly replaced by a phase of inhibition, depression. The smoker, worried by an unpleasant conversation or news, tries to drag on a cigarette as soon as possible: he knows that after several puffs, nicotine will “calm his nerves”. A smoker grabs a cigarette even when he feels tired and wants to regain his former working capacity and improve his mood. He does this because a trace of the once-refreshing effect of a cigarette is tested in his memory, although it was quite short.

Tobacco smoke for a very short time removes the feeling of fatigue and with each cigarette this period of time is shortened. There comes a moment when the fatigue is no longer relieved, And the person is farther and farther away from the goal: instead of the expected surge of strength, lifting, a smoked cigarette more and more complicates the work, inhibiting the activity of the cerebral cortex. Most smokers who are engaged in mental work know from their own experience that by the end of the working day, a cigarette not only does not help restore health, but causes a headache and inability to concentrate. And this is not an accident, but an objective regularity arising from the mechanism of action of nicotine on the body, primarily on the central nervous system.

The report of a special committee of experts of the World Health Organization, summarizing in 1980 all the accumulated observations on the effects of nicotine on human health and performance, states that even in pilots – people with excellent health, tobacco smoking leads to reduced vision, impaired coordination of movements and speed of reaction. Therefore, in addition to harm to the health of the pilot himself, the danger to the life of passengers and the safety of complex equipment becomes real.

Exactly the same situation occurs when smoking while driving a car. It is not for nothing that in some countries drivers are equally punished for driving while intoxicated or with a cigarette in their mouths.

The ability to clearly respond to various signals and quickly make responsible decisions is needed, of course, not only for those who manage various types of transport. In modern highly mechanized production, these qualities are necessary for any worker. be it forge, apparatchik. operator of control panels …

Some researchers with insufficient speed of response in smokers associate a higher frequency of accidents with them at work compared with non-smokers. Fires and explosions also occur often through the fault of smokers.

In order to imagine the scale of disasters. which this straightforward epidemic of smoking brings to humanity, it is necessary to recall the diseases caused by smoking. It is also appropriate to refer to the statements of the WHO expert committee. They show that morbidity and mortality rates among smokers are higher than non-smokers, regardless of gender and age. Smokers are twice as likely to die before they reach the age of 65. According to statistics, among those who died from lung cancer – 90% smokers from coronary heart disease – 25%. And at the same time, experts believe that after quitting smoking, the risk of developing lung cancer gradually decreases and after 10 years reaches the same low level as non-smokers; the risk of dying from coronary heart disease is also reduced. In people who have had a myocardial infarction and quit smoking in connection with this, the risk of re-infarction with a fatal outcome is halved compared to continuing to smoke. There is something to think about!

Speaking about the serious consequences of smoking, they can not be associated exclusively with nicotine. As a result of the high temperature, carbon monoxide (carbon monoxide), tar products, ammonia, benzpyrene and other compounds that make up tobacco smoke are also formed on the tip of a burning cigarette (about 600 ° C). Many of them are carcinogens.

Carbon monoxide contained in tobacco smoke forms a persistent compound with hemoglobin in the blood – carboxyhemoglobin, which is unable to transfer oxygen to body tissues.

And when performing physical and any mental work, the need for muscle tissue and brain tissue in oxygen just increases sharply. Hence, fatigue, poor health, insomnia and other nervous disorders.

Already insignificant doses of nicotine increase the level of adrenaline in the blood, increase the consumption of vitamins, in particular ascorbic acid and thiamine, and reduce the neutralizing function of the liver. Therefore, it is not surprising that the incidence of temporary disability among smokers is much higher than among non-smokers.
