(1) The heart rate increased and blood pressure increased; 2) cough; 3) Decreased vital capacity and poor breathing; 4) The temperature of fingers, toes and skin decreases; 5) Increased gastric acid; 6) Finger trembling; 7) Decreased urine; 8) Loss of appetite, taste and smell; 9) Dizziness and watery eyes; 10) Reduce memory.
Smoking affects many parts of the body, and the most direct effects are mainly two systems: the respiratory system and the circulatory system.
(1) respiratory system
1) Smoking can damage lung function, and sputum and toxic substances cannot be excluded, so bacteria are easy to multiply. Under long-term stimulation, chronic bronchitis and chronic respiratory obstruction are formed, which can further develop into emphysema and coronary heart disease.
2) A large number of carcinogens in tobacco tar adhere to the respiratory tract, which can cause cancers in various parts of the respiratory tract under long-term stimulation, mainly lung cancer, and others include oral cancer, lip cancer and laryngeal cancer.
(2) The influence of smoking on circulatory system
1) Nicotine in cigarettes can increase heart rate and constrict blood vessels at the same time, which is an increase in blood pressure;
2) Long-term contraction of blood vessels leads to hardening of blood vessels, narrowing of lumen and reduction of blood delivery;
3) After coronary atherosclerosis in nutritional myocardium, myocardial oxygen supply decreases, myocardial cells degenerate and die, leading to coronary heart disease;
4) Arterial vascular sclerosis of nutritional brain cells, weakening of vascular wall elasticity, can induce cerebral vascular rupture and bleeding, narrowing of lumen, and even cerebral thrombosis and cerebral embolism, leading to "cerebral stroke";
5) Continuous inhalation of a large amount of carbon monoxide can make the body anoxic, which can aggravate the above lesions.
According to the research results in recent years, American scientists once again put forward the reasons for quitting smoking from the perspective of health in order to attract the attention of the world.
(1) Smoking is not only harmful to health, but also pollutes the environment and harms non-smokers around, especially women and children. Many people know that smoking is harmful to health, but they don't know the seriousness of smoking. It's time for you to quit smoking!
(2) Smoking can easily lead to insomnia. Compared with non-smokers, it is more difficult for smokers to fall asleep and fall asleep. Nicotine in cigarettes can interfere with rapid eye movement sleep, leading to a decline in sleep quality. Smokers are also more likely to snore, and they are prone to fatigue and doze off during the day.
(3) Smokers are prone to diabetes and heart disease. A study of 42,000 men found that compared with non-smokers, smokers are more likely to develop non-insulin-dependent diabetes than 1 times.
The authors of heart attacks among smokers aged 30-40 are five times higher than non-smokers of the same age. A survey of 46,000 smokers in Britain found for the first time that the risk of heart attack of young smokers increased significantly, and the heart attack rate of smokers with medium tar was higher than that of smokers with low tar 10%.
(4) Quitting smoking can reduce the risk of stroke. A study of 7,264 middle-aged men by British scientists confirmed that a large number of smokers (more than/kloc-0 per pack per day) can halve the risk of stroke within five years of quitting smoking. People who smoke less than/kloc-0 per pack a day can reduce the risk of stroke to the level of non-smokers within 5 years of quitting smoking.
(5) Long-term smoking can lead to breast cancer. Research shows that women who smoke for 30 years have a 60% higher risk of breast cancer than other women. The average age of breast cancer in the former is 59, while that of non-smokers is 67.
(6) Female smoking will aggravate mild thyroid diseases, which will obviously aggravate the original mild thyroid diseases of women and may lead to thyroid failure. The study also found that the average serum HDL (beneficial cholesterol) of female smokers was lower than that of non-smokers, so the heart attack of the former was significantly higher than that of the latter.
(7) Wrinkles caused by smoking A study of 1000 people aged 40-49 found that the number of obvious wrinkles of female smokers is three times that of female non-smokers, because smoking will damage vascular connective tissues that are essential to maintaining skin elasticity.
(8) Smoking leads to a high incidence of lung cancer. In the past, people always thought that the death of men from lung cancer was closely related to smoking. Recently, it has been found that the number of women who died of lung cancer due to smoking has also increased significantly.
It is wrong to think that you can quit smoking safely after smoking for several years. Smokers who have quit smoking have a much longer risk of lung cancer than previously thought. A study found that half of lung cancer patients are people who have given up smoking. This is not to say that quitting smoking is useless, but to warn people that it is safer to quit smoking as soon as possible.
The best reason to quit smoking is to set a good example. Since 80% of the people who died of heart disease at the age of 50 were caused by smoking, it is an example for the next generation for parents to give up smoking. Families and society should educate teenagers about the dangers of smoking. Studies have proved that if they don't form the bad habit of smoking before the age of 19, they are unlikely to become smokers in the future.
When a cigarette smokes, your body will undergo the following changes immediately:
(1) increase heart rate and blood pressure; 2) cough; 3) Decreased vital capacity and poor breathing; 4) Finger, toe and skin temperature; 5) increase gastric acid; 6) Finger trembling; 7) Decreased urination; 8) Loss of appetite reduces taste and smell; 9) Dizziness and watery eyes; 10) to reduce memory.
Smoking can affect many parts of the body, and the most direct effects are two systems: respiratory system and circulatory system.
( 1)
1) Smoking can damage lung function, sputum and toxic substances cannot be excluded, and bacteria multiply. Long-term stimulation leads to chronic bronchitis and chronic obstructive airway, and further develops into emphysema and coronary heart disease.
2) A large number of tar smoke carcinogens are attached to the respiratory tract, and long-term stimulation can cause cancers in various parts of the respiratory tract. Lung cancer is mainly other oral cancers, lip cancers and laryngeal cancers.
(2) The influence of smoking on circulatory system
1) Nicotine content in cigarettes will accelerate the heart rate and constrict blood vessels at the same time, which is hypertension;
2) Long-term contraction of blood vessels leads to arteriosclerosis and narrowing of lumen, which reduces blood transmission;
3) Nutrition of myocardium after coronary artery reduces oxygen supply to myocardium, which leads to myocardial cell degeneration and necrosis, leading to coronary heart disease;
4) Atherosclerosis and weakened elasticity of vascular wall of nutritional brain cells can induce cerebrovascular hemorrhage, lumen stenosis, even cerebral thrombosis and cerebral embolism, thus leading to "stroke";
5) Continuous and massive inhalation of carbon monoxide can make the body anoxic, which can aggravate the above diseases.
In recent years, American scientists have found that from the perspective of health, people once again put forward the reasons for quitting smoking in order to attract the attention of people all over the world.
(1) Smoking not only harms one's own health, but also pollutes the environment and harms non-smokers around, especially women and children. Many people know that smoking is harmful to health, but he doesn't know the seriousness of smoking. You quit smoking!
(2) Smoking can easily lead to insomnia, and it is more difficult for smokers to fall asleep and fall asleep compared with non-smokers. Nicotine in cigarettes can interfere with rapid eye movement sleep, leading to a decline in sleep quality. Smokers are also more likely to snore and doze off when they are tired during the day.
(3) Smokers are prone to diabetes and heart disease. A study of 42,000 men found that compared with non-smokers, smokers are more likely to develop non-insulin-dependent diabetes than 1%.
Smokers aged 30-40 are five times more likely to suffer from heart disease than non-smokers of the same age. A survey of 46,000 smokers in Britain found for the first time that the risk of heart disease among young smokers increased significantly, and the probability of heart disease among cigarettes with moderate tar consumption was 65,438 00% higher than those with low tar consumption.
(4) Quitting smoking can reduce the risk of stroke. A study of 264 middle-aged men by British scientists on the 7th confirmed that a large number of smokers (more than 65,438+0 packs a day) can halve the risk of stroke if they quit smoking for five years. However, people who smoke less than 1 pack every day and quit smoking for 5 years can reduce the risk of stroke, which is not the level of smokers.
(5) Long-term smoking can lead to breast cancer. Research shows that women who smoke for 30 years have a 60% higher risk of breast cancer than any other women. The average age of breast cancer is 59 years old, while smokers are 67 years old.
(6) Smoking may increase among women with mild thyroid diseases, and smoking will increase significantly. Indigenous women with mild thyroid diseases may lead to thyroid failure. The study also found that the average serum high-density lipoprotein (good cholesterol) of female smokers was lower than that of non-smokers, and the incidence of heart disease in the former was significantly higher than that in the latter.
(7) Wrinkles caused by smoking 1 000 A study of people aged 40-49 found that the obvious wrinkles of female smokers are three times that of female non-smokers, because smoking will destroy the vascular connective tissues necessary to maintain skin elasticity.
(8) The incidence of lung cancer caused by smoking is high. Smoking has always been closely related to the death of men from lung cancer. Recent studies have found that the number of women who died of lung cancer due to smoking has also increased significantly.
It is wrong to think that it is safe to quit smoking after several years. The duration of smokers quitting smoking has been much longer than the risk of lung cancer previously thought. A study found that half of lung cancer patients are people who have quit smoking. This is not to say that quitting smoking has no effect, but to warn people that it is safer to quit this habit as soon as possible.
The best reason to quit smoking is to set a good example. Since 80% of people who die of heart disease at the age of 50 are caused by smoking, parents must give up smoking as an example for the next generation. Families and communities should publicize and educate teenagers about the dangers of smoking. Studies have proved that if people aged 19 have not contracted this annoying habit before, there is little possibility of becoming habitual smokers in the future.
