What are the dangers of smoking?

There are more than 4000 known chemicals in tobacco smoke, which are the main cause of addiction and health damage. The main harmful substances are nicotine, tar, carbon monoxide, etc. Nicotine can cause vasoconstriction, rapid heartbeat, increase blood pressure, damage vascular intima, aggravate arteriosclerosis, cause coronary artery spasm, induce angina and myocardial infarction. Tar is the main cause of lung and throat cancer, and it can aggravate the symptoms of asthma and other lung diseases. Carbon monoxide is a substance that forces oxygen out of red blood cells, causing anoxia, increasing cholesterol and accelerating atherosclerosis.

Smoking is closely related to cardiovascular and cerebrovascular diseases, lung cancer and other diseases.

The blood viscosity of people who often smoke will change, and the acid substances such as carbon dioxide in their bodies will also increase, which will affect the permeability of red cell membrane and the deformability of red cells, promote a large number of red cells and platelets in the blood to gather, increase the viscosity of the whole blood and form thrombus. If thrombus occurs in the heart, it is myocardial infarction; if thrombus occurs in the brain, it is stroke. Smoking can cause heart damage and increase the risk of coronary heart disease. Smoking can cause damage to blood vessels in the brain and neck and increase the risk of stroke. The greater the amount of smoking, the longer the smoking period, the higher the risk of morbidity and mortality of coronary heart disease and stroke.

The longer the smoking time, the greater the amount, the higher the risk of lung cancer. Smoking is also prone to chronic bronchitis, emphysema, cor pulmonale and COPD. Smoking is related to oral cancer, throat cancer, breast cancer, pancreatic cancer, renal cancer, leukemia, cervical cancer and other cancers. Smoking can also lead to male sexual dysfunction and male infertility.

Stop smoking scientifically and try these measures

1. Tell people you're quitting smoking

The success or failure of quitting smoking lies in environment and temptation. The more people know you quit smoking, the less likely you are to be tempted to smoke. So avoid situations, activities, and things that tempt you to smoke, and try to find new environments that can help you quit.

2. Choose a suitable way to quit smoking

One time total abstinence: one day before you quit smoking, smoke enough until you hate the smell of cigarettes, and then discard cigarettes, ashtrays, lighters and other smoking devices that may cause you to smoke.

Reduction method: in places where smoking is restricted, try not to think about smoking. When you really want to smoke, take out a cigarette and put off the time of lighting the cigarette as much as possible. In this way, a few less cigarettes a day and a long time can also achieve the goal of quitting smoking.

Other methods can be used as long as they are suitable and effective.

3. Learning to deal with the discomfort after quitting smoking

Tired: take a nap and give yourself more sleep.

Nervousness: take a walk, take a hot bath and do something to relax your nerves.

Headache: lie down and take a deep breath, take a hot bath or take a hot bath.

Grumpy: tell the people around you that you are quitting smoking. If you have a temper in these days, please forgive them.

4. Resist the idea of smoking with healthy thoughts

When the mood is troubled, relax yourself, do deep breathing, meditation, relax muscles, practice yoga, Taiji, listen to music, watch TV, etc. can help you relax. In addition, you can share your stress and trouble by talking to more people.

When you really think it's difficult to quit smoking and you can't stop smoking by yourself, you can ask a professional doctor for help.

In addition, the support of family and friends in the process of quitting smoking is also crucial for the success of quitting smoking.

5. Stand the test of smoking again

Smoking again after quitting smoking is not equal to quitting smoking failure. It's not 'too late' after smoking a cigarette or a mouthful of cigarettes, but it's necessary to carefully analyze the reasons for re smoking to avoid future recidivism.
