When is smoking the least harmful to health?

First, replenish enough water before smoking.

Smokers' chronic tracheitis, emphysema, cor pulmonale and even cancer are all directly related to long-term smoking in the state of water imbalance! Water is the source of life and the foundation of human body, and water is the natural nemesis of tar. Water can excrete most harmful substances produced during smoking through urethra. When the water in the human body is out of balance, many organs such as heart, lung, spleen, liver and kidney can't function normally. After getting up in the morning, sweating, exercising or thirsty, the body's water has lost its balance. At this time, the body's first need is hydration, not smoking.

Therefore, healthy smoking requires smokers to smoke while maintaining the water balance of human body, and develop the habit of drinking water before smoking.

Second, the cigarettes that have just been opened should be released before smoking.

Newly bought cigarettes, the cigarette case has just been opened, so you can't smoke immediately! Just like a newly renovated house can't be moved in immediately, it needs ventilation for a few days. This is because all kinds of chemical additives, adhesives and cigarette packaging materials added in the process of cigarette production are instantly packaged in cigarette cases at the speed of 2500- 1 10,000 cigarettes per minute. After opening the packaged cigarette case, all kinds of peculiar smells and harmful components produced by printing ink, various chemical additives and adhesives and non-tobacco substances must be fully released before the original color of tobacco can be restored.

So, open the cigarette case and let the cigarette evaporate in the air, and then smoke it after three minutes; This will greatly reduce the harm of smoking to human body.

Third, a cigarette should be smoked at one time.

Now, some smokers have a strong sense of health. Some smokers smoke a cigarette several times in order to smoke less, and then smoke it after stubbing it out, but he doesn't know that the cigarette he smokes again is carbonized cigarette formed after stubbing it out!

Carbonized cigarettes can't be smoked! There are many tar and harmful substances in the carbonized part of cigarettes, and it takes several times of smoking power to ignite again, bringing more harmful substances into the body. Therefore, you can't smoke a stubbed cigarette.

Fourth, we should smoke intermittently.

Smoking one cigarette after another is a bad smoking habit, which is no less harmful to human health than overeating. According to our survey, most smokers with joint smoking habits smoke flue-cured tobacco. In fact, for smokers, the best way to reduce smoking is to switch to stronger tobacco products. Generally, the physiological intensity of mixed tobacco is higher than flue-cured tobacco, and cigars are higher than mixed tobacco. Smokers' smoking frequency and smoking intensity can be automatically adjusted by stronger tobacco products, so as to reduce their smoking. Fifth, choose low tar cigarettes between low tar and high tar.

Tar is the main substance that harms human health and causes cancer in cigarettes, and it is not easy to be discharged by human body. Reducing harmful components and tar content in flue gas has become a top priority at present. Tar in smoke will be concentrated into a sticky substance in the lungs, which will attach to the surfaces of the trachea, bronchi and lungs of smokers, causing physical and chemical stimulation and affecting human breathing.

Therefore, under the premise of ensuring the satisfaction and taste of smoking, try to choose cigarettes with low tar.

6. Choose mixed tobacco between mixed tobacco and flue-cured tobacco.

As mentioned above, in general, the physiological intensity of mixed cigarettes is higher than that of flue-cured cigarettes, so it can bring more satisfaction to smokers, that is, reduce the number of smokers. Moreover, through the collocation of different kinds of cut tobacco, mixed cigarettes can make researchers control the components in cigarettes more effectively, and achieve the purpose of reducing coke and harm.

Seven, in the natural aroma and artificial aroma of tobacco products, choose products with strong natural aroma.

In recent years, people pay more and more attention to natural and organic foods and supplies, which bring people healthier consumption and become a new consumption fashion. Natural and healthy cigarettes should also pay attention to the natural degree of materials. Cigars and dry cigarettes are handmade without any additives, which is the least harmful to human health. However, there are many restrictions on smoking such tobacco products, which are not suitable for mass consumption.

Therefore, when choosing cigarettes, it is best to pay attention to the taste of tobacco and choose products with less artificial addition.

Eight, choose a new cigarette among the old and new cigarettes.

The new and old here refers to the new and old put on the market, not the production date. Some cigarettes are ten or even decades old brands, which are supported by many smokers. However, most of the formulas of these cigarettes have not been improved, and they have fallen behind the times and cannot meet our health needs. Therefore, choosing new cigarettes, in which technology has more applications, will bring more protection to our health. For example, Zhongnanhai 10mg to 3mg cigarettes are made of activated carbon, colored cellulose, biological filter and nano-filter, respectively, to achieve the purpose of reducing coke and harm, while the latest I-era 5mg cigarettes are made of ordinary filter, which also reduces tar content to 5mg/ cigarette. This is because in the I era, 5mg also achieved the purpose of reducing coke through other means and technologies such as expanded smoke and high-permeability cigarette paper, which fully shows that Zhongnanhai's coke reduction technology has become more comprehensive and mature, thus ensuring consumers to feel comfortable and smooth during smoking, which is a perfect embodiment of scientific and technological progress.
