Do you know the harm of smoking?

Many people think that smoking is a very comfortable thing, but what you don’t see are some of the harms behind smoking. The most obvious point is that people who smoke a lot will look more listless. After smoking a lot, you will find that your physical condition has really deteriorated a lot, and smoking a lot will cause chest pain. So what other harms are there?

Brain: Smoking can cause a variety of brain diseases, reduce the oxygen and blood circulation in the brain, cause bleeding and blockage of brain blood vessels, and lead to paralysis, mental decline and stroke.

Throat: Smoking can cause laryngeal cancer. Most of the patients with laryngeal cancer are male. Otolaryngologists have found that most smokers have hoarse throats. This may be related to the tar in the smoke. As for the heart and blood vessels, studies have found that smoking increases the viscosity of platelets in the blood, which makes the blood easier to coagulate, making it easier to form blood clots in the coronary arteries. At the same time, smoking also increases the low-density cholesterol in the blood, which makes it easy for fatty substances to deposit in blood vessels and form coronary atherosclerosis. If the coronary artery becomes hardened, its inner lumen will become narrower. Once the blood coagulates inside, the artery will be blocked. At this time, oxygen cannot be delivered to that part of the heart muscle, and the myocardial cells will fail and die due to lack of oxygen. This is myocardial infarction. Local myocardial infarction can cause angina pectoris, while large-scale myocardial infarction can cause shock or death due to sudden cessation of heart beating. This is acute myocardial infarction. Smoking causes blood vessels to constrict, slowing down blood and oxygen circulation, eventually leading to thickening of blood vessel walls and inducing coronary heart disease and stroke. Smoking can completely block blood flow to the hands and feet, leading to amputation. Doctors' advice to smokers is: If you have high blood pressure, high blood lipids, heart disease or a family history of heart disease, you should stop smoking immediately, because smoking will increase your risk of myocardial infarction by dozens of times.

So you must not think that smoking makes you feel comfortable. Often times this will create a sense of dependence, and smoking may not only affect you, but sometimes it will also have a certain impact on people around you. So everyone should really pay attention to this aspect and not harm others.
