What harm does smoking do to your health?

May 3 1 day is World No Tobacco Day. Everyone knows that smoking has many hazards. Now come with me to understand the harm of smoking to your health.

The harm of smoking to health. Smoking can lead to blood clots and various heart diseases.

Inhaling carbon monoxide in cigarettes will reduce the ability of blood to absorb oxygen. Nicotine can make the heart beat faster, raise blood pressure, weaken cardiac endurance, cause coronary infarction due to myocardial hypoxia, promote the accumulation of atherosclerosis due to cardiac ischemia (or heartache), and many heart diseases begin to occur.

Between the ages of 30 and 49, smokers have a very high probability of heart disease, which is five times that of non-smokers. Quitters found that their chances of heart disease dropped by half after one year.

Second, the damage of smoking to the brain.

Smoking can cause various brain diseases, reduce oxygen and blood circulation in the brain, lead to cerebral vascular bleeding and occlusion, and lead to paralysis, mental decline and stroke. The cause of stroke is that smoking leads to cerebral vasospasm, which makes blood coagulation easier. Smokers are twice as likely to have a stroke as nonsmokers.

Third, the harm of smoking to the oral cavity.

Smoking can lead to oral cancer and laryngeal cancer. The heat of tar and smoke in cigarettes will inflame salivary glands, damage taste buds and greatly weaken the ability of taste and smell. Next, it is easy to cause oral cancer, and about 2/3 patients can still live a hard life after discovering oral cancer. At the same time, smoke can make the temperature in the throat drop from 37? C increased to 42? C, causing minor burns to the mucosa inside, causing chronic thermal trauma, and eventually leading to laryngeal cancer.

Fourth, the damage of smoking to the lungs.

Smoking can lead to short and irregular cilia of bronchial epithelial cells, dyskinesia, reduced local resistance and susceptibility to infection. Smoking can cause lung cancer. 90% of the total mortality rate is caused by smoking. The initial symptoms will not be found until the cancer cells spread to blood vessels and other organs. Smoking can also cause emphysema, and toxic substances accumulated in the bronchi of the lungs will hinder the normal exhalation of the air inhaled by the human body, make lung cells expand or rupture, and cause patients to have difficulty breathing.

Fifth, the damage of smoking to the stomach.

People with gastrointestinal diseases, smoking is enough to make gastrointestinal diseases worse. People with gastric ulcer or duodenal ulcer will slow down the healing of ulcer and even become chronic diseases. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, make the gastrointestinal tract often tense, and lead to the loss of appetite of smokers. In addition, nicotine can also contract gastrointestinal mucosal blood vessels and reduce appetite.

Six, smoking damages the whole body bones.

Nicotine constricts blood vessels and reduces blood flow to new bones. The carbon monoxide inhaled during smoking also reduces the speed at which oxygen enters the body. Smoking can lead to osteitis and back pain, and most people with severe back pain are addicted to smoking. This is because smoking will reduce the blood flow of the articular disc, and the articular disc will degenerate early. Smoking can lead to arthritis. Smoking a pack of cigarettes a day will increase the prevalence rate by 50%. Smoking will lead to faster bone loss. Smoking can interfere with estrogen, which is an important hormone in bone development.

There are three major hazards of smoking in the car: First, serious carbon monoxide poisoning.

Many car owners think it's no big deal to turn on the air conditioner and smoke in the car.

So, is smoking harmful in such an environment? Can air conditioning eliminate smoke? Experts say that when the vehicle is in a closed state, the operation of the automobile engine itself will produce harmful gases such as carbon monoxide, which will flow into the car and endanger human health. What if? Smokers? If you smoke in this situation, the concentration of carbon monoxide in the car will be as high as 30 times higher than the normal value, which will lead to dizziness, fatigue, nausea and other symptoms, and even serious poisoning.

According to experts, I have met patients with carbon monoxide poisoning caused by smoking in a closed car for a long time. Because carbon monoxide is a colorless, odorless and non-irritating gas, the patient did not notice it at that time. It was not until there was a disturbance of consciousness that the car stopped on the road and was found by the traffic police and sent to the hospital in time, saving a life.

Hazard 2: The car is yellow, and smoking is very strange.

Frequent smoking in the car will not only leave an unpleasant smell, but also some fungi and bacteria will breed under the mat and in the gap. At this time, it is best to give the vehicle a thorough? Sauna? Is to fill the interior of the vehicle with high-temperature steam. After steaming, the dirt attached to the surface can be wiped off. After repeating it for three times, wipe it with clean water with disinfectant to remove fungi and bacteria, and finally wipe it thoroughly with clean water. After this procedure is completed, it needs to be aired, and it can't be driven away until the water vapor is completely dispersed. It usually takes more than two hours to wait, and the price is relatively expensive.

Hazard 3: Increase the maintenance cost of air conditioning system.

Smoking will also turn black. Roof smallpox. In the used car market, some vehicles with poor interiors and bad smells are often two or three thousand yuan cheaper than used cars with clean interiors. If the owner is used to smoking in the car, the smoke circle will surround the space inside the car and it will be difficult to disperse. Over time, smallpox will be smoked brown and smelly. In order to avoid the smoke remaining indoors, some car owners will lower the left window when driving or parking, and put their left hand holding a cigarette out of the window to smoke smartly, which will cause traces of smoke at the A-pillar position on the driving side.
