What are the dangers of smoking

I believe everyone has heard about the harmful effects of smoking before. Indeed, smoking brings great harm to our lives and all aspects of our bodies. On a large scale, it harms our bodies. On a small scale, it also brings a serious burden to our living funds. The money spent on smoking could have been used to do more meaningful things. I believe everyone still doesn’t know much about the specific harmful effects of smoking. Let us learn about the harmful effects of smoking together.

Hazards and impacts:

1. Smoking shortens life span: When talking about the harms of smoking, we have to talk about life span. According to some surveys, on average, every cigarette smoked will shorten life span by 11 minutes. Of course, this number may not be accurate, but one thing is certain: non-smokers live longer than smokers.

2. Smoking affects sleep quality: According to a recent survey by German scientists, smokers sleep less than non-smokers and have poorer sleep quality. Among them, nicotine is the main culprit that affects sleep. Poor sleep quality will not only make people in a bad mental state after waking up, but some studies have also shown that if poor sleep quality is habitual, it will also cause health problems such as obesity, diabetes, and heart disease.

3. Smoking affects reproductive function: According to research surveys, the sperm fertilization ability of long-term smokers is reduced by 75% compared with non-smokers. The main culprit is still the nicotine in cigarettes, as sperm can recognize nicotine and react to it. Long-term smoking overloads the nicotine receptors in human sperm, thereby reducing the ability to fertilize.

4. Smoking increases the risk of miscarriage: Pregnant women smoking not only harm their own health, but may also cause harm to the fetus in the belly. The nicotine and alkali contained in cigarettes can cause vascular diseases throughout the body, affecting the uterine blood vessels. Smoking makes miscarriage more likely in early pregnancy and one of the most dangerous complications of pregnancy - gestational hypertension - occurs in mid-pregnancy.

5. Smoking causes lung diseases: Smoking is one of the main causes of chronic bronchitis, emphysema and chronic airway obstruction. Smoking can cause changes in the structure and function of the central and peripheral airways, alveoli and capillaries, and affect the lung's immune system, leading to the occurrence of lung diseases.

6. Smoking induces cardiovascular diseases: Smoking not only induces lung diseases, but also cardiovascular diseases. Studies have shown that the incidence of coronary heart disease, hypertension, cerebrovascular disease and peripheral vascular disease in smokers is significantly higher than that in non-smokers. The pathogenesis of cardiovascular disease induced by smoking is mainly that smoking causes endothelial dysfunction, increased thrombosis, enhanced inflammatory response and oxidative modification.

7. Smoking causes osteoporosis: Can smoking a cigarette cause osteoporosis? Many smokers may have such doubts. Smoking can indeed cause osteoporosis. The principle is that nicotine in tobacco can affect the absorption of calcium, nicotine inhibits osteoblasts, stimulates the activity of osteoclasts, etc., not to mention other things. Insufficient calcium intake alone will cause some bone calcium to be released into the blood to maintain normal blood calcium levels. This will reduce bone density and cause osteoporosis.

Smoking causes cancer: It is a recognized fact that smoking causes cancer. Smoking is not only one of the important risk factors of lung cancer (smokers are 13 times more likely to develop lung cancer than non-smokers), but also has a certain relationship with the occurrence of lip cancer, tongue cancer, oral cancer, esophageal cancer, stomach cancer, colon cancer, pancreatic cancer, kidney cancer and cervical cancer. Studies have shown that carcinogens in smoke can also affect the fetus through the placenta, causing a significantly increased incidence of cancer in their offspring.

The above introduction tells us about the dangers of smoking, and we should all pay attention to it. After all, it is related to the physical health of each of us. We can also tell more people about the above dangers so that others can be free from the troubles of diseases caused by smoking.
