Although we all know that smoking is harmful to health, many people still smoke in life. Even with the opening of social freedom and ideas, many women also like smoking. We all know that smoking is harmful to health, but we don't necessarily know what the specific hazards are. This article will make an inventory of the hazards of smoking and when smoking is the most harmful.
When is smoking harmful
1. A cigarette in the morning is a good spirit. The first thing 'old smokers' do when they wake up in the morning is to light a cigarette. They also call it' morning cigarette refreshing '. As everyone knows, after a night, the air in the room was not circulating, it was very dirty, and the smoke mixed with cigarettes was sucked into the lungs again; In addition, fasting smoking, smoke will stimulate bronchial secretion of liquid, over time will lead to chronic bronchitis. There is a folk proverb: 'smoking in the morning, returning to the West early' has sounded an alarm for people.
2. A cigarette after a meal is better than a living fairy, which is a very harmful misleading to smokers. After a meal, the amount of blood circulation increases, and nicotine is quickly absorbed into the blood, making people excited and floating in the head. In fact, smoking one cigarette after a meal is more toxic than smoking ten cigarettes. Because the body heat increases greatly after meals, smoking will inhibit the basic secretion of protein and bicarbonate, hinder food digestion and affect nutrient absorption. At the same time, it also causes direct damage to the stomach and duodenum, resulting in gastrointestinal dysfunction, increased bile secretion, easy to cause abdominal pain and other symptoms. Moreover, while the body actively digests and absorbs food, the absorption capacity of cigarette smoke is also enhanced, and the intake of harmful substances is also increased.
3. Friends chat, drink and smoke. Many people like to smoke while drinking. They think that when friends get together, they must have good wine and smoke, so as to have a good atmosphere. Both are indispensable. But you may not know that drinking and smoking together is more toxic than drinking or smoking alone. Because alcohol will dissolve in cigarette tar and promote the transfer of carcinogens to the cell membrane. Statistics show that 70% of oral cancer is associated with both smoking and drinking. What is more serious is that tobacco and alcohol are carried out at the same time, so that the liver metabolic function can only take into account the elimination of alcohol, but it is difficult to take into account others. As a result, the toxic substances of tobacco stay in the human body for hours or even days, increasing the harm of tobacco to the body. Therefore, smoking while drinking is essentially a joke on health and life.
4. Many people think that there is a bad smell in the toilet and smoking can be diluted. In fact, the concentration of ammonia in the toilet is higher than that in other places, and the content of oxygen is relatively low, while tobacco will produce more sulfur dioxide and carbon monoxide under low oxygen. Together with a large number of toxic gases and pathogenic bacteria in the toilet, they are inhaled into the lungs, which is very harmful to the human body. Smoking in the toilet by patients with coronary heart disease or chronic bronchitis can lead to acute attack of angina pectoris, myocardial infarction or tracheitis. The lung of long-term smoking accumulates a lot of toxins and its function is damaged.
