Publicizing knowledge about the harms of smoking

Many male friends like to smoke, and it is difficult for you to quit smoking, but you must know the harm of smoking. Long-term smoking will shorten your lifespan, affect your reproductive function and sleep quality, so we recommend that you quit smoking. If female friends smoke on a regular basis, it will affect the development of the fetus and the formation of egg cells. I hope everyone will avoid contact with cigarettes.

1. Smoking shortens life expectancy: When talking about the harms of smoking, we have to talk about life expectancy. According to some surveys, on average, every cigarette smoked will shorten life expectancy 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 alkali and nicotine contained in cigarettes can cause vascular diseases throughout the body, and the uterine blood vessels are therefore affected. Smoking makes miscarriage more likely in early pregnancy and one of the most dangerous complications of pregnancy - gestational hypertension - occurs in mid-pregnancy.

From the above analysis of the knowledge on the hazards of smoking, I believe everyone should know the disadvantages of smoking in daily life. Smoking in your life has a great impact on our lungs. It can easily lead to diseases such as lung cancer and liver cancer. Smoking also shortens our lifespan and affects our reproductive function.
