What should we pay attention to regarding the harmful effects of smoking on health?

In real life, many people have the bad habit of smoking. It is easy to become addicted to smoking over time, and the hidden dangers to human health are still very great. So what should we pay attention to about the harm of smoking to health? There are still many nicotine and other toxic and harmful ingredients in cigarettes.

Smoking shortens life expectancy: When talking about the dangers of smoking, we have to talk about life expectancy. According to some surveys, on average each 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.

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.

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.

Smoking increases the risk of miscarriage: Pregnant women smoking not only endanger 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.

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.

Through the above introduction, everyone is clear about what to pay attention to regarding the harmful effects of smoking on health. No matter what kind of living habits you have, as long as they threaten human health, you still need to be vigilant and gradually improve your lifestyle and habits to improve your quality of life while ensuring your health.
