The harm of smoking on the endocrine system

Numerous studies have shown that smoking adversely affects the endocrine glands. Particularly gonads are affected by tobacco. Toxic substances from the cigarette smoke are poisoning the sexual glands, which is connected with the occurrence of impotence among men. Inspecting the women who worked at tobacco processing factories, scientists have identified the harmful effects of hazardous substances in their body. Women had menstrual disorders, toxemia of pregnancy and miscarriages were more common. Smoking is also harmful to other endocrine glands (thyroid, adrenal glands).

The harm of smoking on the digestive organs

Once in the mouth, cigarette smoke irritates the tongue, gums, pharynx, it adversely affects the tooth enamel, and it begins to crack. Very often the mouth of a smoker has an unpleasant smell. Cigarette smoke irritates the salivary glands, resulting in excessive salivation. Scientists have found that smoking is a direct path to cancer of the lips and tongue.

The World Health Organization’s study revealed that cancer of the oral cavity and esophagus are four times more common among smokers than non-smokers. The poisoning effect of tobacco smoke is associated with mechanical, thermal and chemical impact. Toxic substances from tobacco smoke get into the digestive organs in many ways. Poisons penetrate the digestive system through the central nervous system, with the saliva, as well as through the circulatory system.

Statistics show a direct link between smoking and peptic ulcer and duodenal ulcer. Deaths from these diseases occur 3-4 times more often among smokers than non-smokers. Tobacco smoke irritates the stomach lining and causes increased secretion of gastric juice with higher acidity. The constant irritation of the stomach can cause the development of chronic gastritis. Nicotine inhibits contraction (peristalsis) of the stomach and intestines. Doctors studying this phenomenon found that a smoked cigarette slows the reduction of the stomach, and sometimes stops it completely. Thus, smoking inhibits the motor action of intestinal function. This explains the smokers’ poor appetite and poor digestion.

Smoking also causes harm to the liver. Scientists have conducted experiments on rabbits and observed irreversible changes in the liver of these animals. Smokers often have enlargement of the liver, which stops if a person quits smoking. Smoking also has an effect on the pancreas. Smokers have twice the risk of cancer than that of non-smokers. If a non-smoker constantly stays in a smoke-filled room, he has a danger of chronic gastrointestinal disease.

The harm of smoking on the cardio - vascular system

The harm of tobacco smoking on the cardiovascular system is complex and diverse. During smoking, the heartbeat quickens after the first puff. A healthy human heart beats 70 times per minute, and during smoking - 80-90 times per minute. One heartbeat surpasses 60-70 milliliters of blood, at 70 beats per minute, the heart will pump 4-6 liters of blood, 300 liters in 1 hour, and over 7,000 liters in 24 hours. Now imagine that the heart beats 85 times per minute instead of 70 times, which is 21% more.

By simple calculations, we can determine that the heart has to pump 8,470 liters of blood in 24 hours, which is almost 1,500 liters more than in normal conditions.

That’s the additional burden that our heart needs to carry!

If a person is healthy, this burden on the heart is not too heavy, but if a person has a heart condition, then the burden is carried with difficulty. Experiments showed that during smoking, the adrenal glands secrete hormonal substances that can cause high blood pressure. This further increases the burden on the heart.

The heart expends more energy to surpass blood through significantly reduced blood vessels. While the diameter of the vessels reduces, the blood flow to organs worsens, and the temperature of skin decreases. Inhalation of carbon monoxide increases the content of carboxyhemoglobin in the blood of smokers, which impairs oxygen supply to the heart muscle.

Scientists have found that smoking contributes to the development of atherosclerosis. An important role here is played by the increase of catecholamine products that appear during smoking. Catecholamines contribute to an increase in the concentration of lipids (fatty substances) in the blood, which may cause the formation of atherosclerotic plaques in blood vessels. It is also known that toxic substances from tobacco smoke in the blood prevent absorption of vitamin C, the deficiency of which causes the deposition of cholesterol on the walls of blood vessels, which narrows the vessels.

Poor blood supply to the heart leads gradually to its fatty degeneration. Thus, smoking may cause atherosclerosis, which, in turn, can lead to increased incidence of coronary heart disease. Coronary diseases include all heart diseases and disorders associated with a sharp decrease (general or localized) of blood flow in the blood vessels that feed the heart.

The harm of smoking on the respiratory system

The respiratory system takes on the very first punch of tobacco poisons. The dense particles of soot and everything that tobacco smoke contains, irritate the mucous membrane of the larynx, trachea, bronchi, smallest bronchioles and pulmonary bubbles - the alveoli. As a result, exposure to tobacco poisons develops chronic inflammation of air passages. Smokers often suffer from bronchitis, and they are constantly tormented by a cough, especially growing in the morning.

A cough is accompanied by copious expectoration of dirty gray sputum. The constant irritation of the vocal cords, which is common among smokers, makes their voice rough, hoarse, and unpleasant. That, in turn, can become a barrier to professional activity (e.g. singers, teachers).

In one year, the lungs of a smoker take about 800 grams of tobacco tar. Therefore, smoker's lungs become darker than the lungs of a non-smoking person. Permanent, painful cough entails a reduction in the elasticity of the lung tissue, causing stretching of the alveoli and the development of lung emphysema. Scientists have shown that smokers’ lung functions are less full-bodied in every respect. Lungs’ resistance to infectious diseases becomes significantly reduced.

Doctors have established a direct link between smoking and tuberculosis. Smokers have tuberculosis twice as often as non-smokers. Smoking is one of the first causes of lung cancer. Statistics say that people who smoke have 10 times higher expectation to get lung cancer than non-smokers. Studies conducted in the US and Europe have shown that the risk of lung cancer increases directly in proportion to the number of cigarettes smoked. The expectation especially increases if smokers are accustomed to using half-smoked cigarettes and make deeper inhaling.

Pathologists’ researches have shown that smokers often have neoplasm of the bronchi, which are considered a pre-cancerous disease. And those who quit smoking have a significantly reduced risk of cancer. In several countries, scientists have studied the previous life of the lung cancer diseased, and have come to the conclusion that the majority of patients were tobacco smokers. Smoking can also cause cancer of the stomach, as a smoking person is constantly swallowing saliva, in which toxic products from the burned tobacco are dissolved. Scientists experimentally proved that tobacco contains carcinogenic compounds. Back in 1930, the Argentine doctor Roffo was greasing for 270-300 days the ears of rabbits with substances derived from tobacco tar, and then cancerous tumors started developing there.

Roffo’s experiments were repeated by other scientists with the same invariable results. In other experiments, researchers found that tobacco smoke contains a potent carcinogen - benzpyrene, which plays the first and primary role in the development of malignant tumors, it’s also considered fatal for humanity. In addition, smoke from cigarettes contains other dangerous substances which can also cause the development of cancer - chrysene, di benzantrene, di benzpyrene, and others.

Cigarette smoke also contains secondary amines which are soluble in the saliva and form nitrosamines in the stomach, which can cause cancer. Tobacco contains both natural and artificial radioactive elements. Finished goods (cigarettes, cigars) contain the radioactive isotope in a smaller amount than tobacco. This is explained by the fact that radioactive Polonium disintegrates during tobacco processing at factories and storage of finished goods in warehouses. A number of studies carried out to study the content of polonium in tobacco combustion products determined that the ash contains about 9% of the isotope, the cigarette butt - 20%, the filter - 8%, and the smoke - 50%.

As these figures show, half of the harmful substance is contained in cigarette smoke, so it is inhaled into the human body. From these data, we can conclude that stopping smoking tobacco would undoubtedly have reduced the incidence of such a serious and life-threatening disease like lung cancer.

The harm of smoking on the senses

Sensory organs also suffer from toxic substances released during smoking. How does smoking affect the senses? For example, many smokers don’t like sweets because nicotine kills gustatory nerve endings in the mouth, which leads to the disappearance of taste perception. Hard-core smokers often have problems with vision - sometimes they lose color perception and can’t distinguish colors.

This is due to the influence of tobacco poisons on the optic nerve. Smoking also has a negative effect on the hearing function. Smokers' ears are popped by toxic substances released during smoking. They have a negative effect on the hearing organ, destroying the auditory nerve, thus reducing the sharpness of the sound sensations. The medical literature has repeatedly described the harm of smoking on the human body when the constant tobacco poisoning of the body causes disease of the peripheral nervous system. If a person suffers from diseases of the nervous system, smoking can worsen the state of health and, in some cases it can lead to severe disability.

The harm of smoking on the nervous system

Of all the systems of the body, the nervous system primarily suffers from smoking. The nervous system controls all the processes occurring in our body. It is responsible for connecting the body with the internal and external environment. And the nervous system is the first and foremost to suffer from tobacco poisoning. One of the first signs of tobacco poisoning of the nervous system is dizziness.

Dizziness usually comes in bouts, and sometimes in a succession of intense bouts. First, there is a feeling of emptiness, a person is unable to concentrate and gets a feeling of loss of consciousness. It seems that everything is moving, and if the person closes his eyes, he gets a feeling of his own body whirling. Constriction of cerebral vessels causes dizziness, which often occurs during smoking. Experienced smokers develop symptoms of a neurotic condition - fatigue, irritability, memory loss, nervousness, and headaches.

Smoking causes irreparable harm to the human body

Has a smoker ever wondered at least for a second about the processes that are taking place in his body and about the harm smoking does to it? Probably not. But he should!

The smoke of 20 cigarettes (which is the usual heavy smoker’s daily dose) contains 130 mg of nicotine, 45 g of ammonia, 0.7-1.1 mg of hydrocyanic acid, 0.6 l of carbon monoxide and many other toxic substances.

These substances cause irreparable harm to the human body. Doctors have proved that a smoker’s average life expectancy is nine years less than a non-smoker’s.

Once in Nice, there was a competition, very unusual in its absurdity and cruelty, "The Best Smoker Award". The competition was attended by many people who wanted to get the "honorary title", and here’s what it led to. Two participants of the competition smoked 60 cigarettes each and died in a hospital a few hours later.

Many participants got the strongest poisoning, but they were rescued. What a sad result this competition had. Ask a novice smoker how he feels when he smokes a cigarette. After he smokes a cigarette he immediately begins to feel dizzy and sick, his heartbeat quickens, the body becomes pale; he gets cold sweat, and those are obvious signs of poisoning. Medical literature has repeatedly given examples of the harm of smoking to the body, and tobacco poisoning. Here are a few examples:

A 42-year-old man who was smoking a tobacco pipe 3-4 times a day made a bet with his friend, which one of them could smoke more pipes in a row. After he had smoked 25 pipes, he felt ill. He had a strong weakness, nausea; he began vomiting, and as a result, he lost consciousness. The man was saved from death, but he suffered severe headaches for one and a half years after that.

A middle-aged man smoked 20 cigars and 40 cigarettes in twelve hours. As a result, he had a breakdown, cold, clammy sweat, disruptions of cardiac activity, and convulsions. The sad end of the story – the man died. Two young men made a bet which one of them could smoke more cigarettes in a row, and after 12 smoked cigarettes, one of them fell ill. He became dizzy, and he died of sudden cardiac arrest. The harm of smoking on health is very diverse. Every part of the human body suffers from the chemicals in tobacco.
