A: I really haven't heard of smoking cessation supplements, but I know that smoking seriously hinders the improvement of sports performance. The active ingredient of cigarettes is nicotine. Although nicotine stimulates adrenal gland to increase energy, its long-term side effects far exceed its possible positive effects. After nicotine is inhaled into the lungs, the workload of the heart increases. This phenomenon can be obtained by detecting the pulse of smokers after smoking: the heartbeat is accelerated and aggravated. For most smokers, nicotine can cause irregular contraction of the heart for 30-45 minutes. Smoking will not only increase heart rate, but also increase blood pressure and ventilation resistance. Dyspnea, arterial contraction leads to high blood pressure. This reaction also occurs in the heart arteries, reducing the blood flow of the myocardium. The by-product of smoking is co, which is easily combined with oxygen, and the amount of oxygen used for muscle work is reduced, so muscle endurance is greatly reduced. Smoking also reduces the oxygen content in the lungs by nearly half. A large number of toxic products of smoking are related to cancer, heart disease and other degenerative diseases. Smoking can reduce the body surface temperature, make people feel cold, and reduce the functional level of the body during exercise or competition. Other forms of tobacco are nasopharynx and chewing tobacco, which also have side effects. In addition, nicotine mixed in saliva passes through the throat, which is easy to cause various forms of oral cancer.

So now that you have invested in health, I suggest you give up smoking.
