Smoking can cause a variety of cardiovascular diseases to be recognized, including high blood pressure. Studies have shown that the rate of heart rate increases by 5-20 times per minute after smoking, and the systolic blood pressure increases by 10-25mmHg. In untreated hypertensive patients, the 24-hour systolic blood pressure and diastolic blood pressure of smokers were higher than those of non-smokers; especially nighttime blood pressure was significantly higher than that of non-smokers, and nocturnal blood pressure was directly related to left ventricular hypertrophy. In other words, smoking can cause high blood pressure and adversely affect the heart.
Tobacco contains a variety of harmful substances, including the main material nicotine (nicotine) will stimulate the central nervous system and sympathetic, so that the heart rate, but also to promote the release of a large number of catecholamines in the adrenal glands, so that small arteries contraction, leading to elevated blood pressure. Nicotine also stimulates blood vessel chemoreceptors and reflexively raises blood pressure. Long-term heavy smoking also promotes atherosclerosis in the large arteries, and the intima of the small arteries gradually thickens, gradually hardening the entire blood vessels. At the same time, due to the increase of carbon monoxide and hemoglobin in the blood of smokers, the oxygen content in the blood is reduced, the oxygen in the arterial intima is reduced, and the lipid deposition in the arterial wall is increased, which accelerates the formation of atherosclerosis.
Therefore, people who do not have high blood pressure can prevent the occurrence of high blood pressure, and those who already have high blood pressure should quit smoking. The study found that smoking is not only harmful to themselves, but passive smokers are no less harmful than smokers. Therefore, smoking has all but one disadvantage.
Compared with smoking, there are great controversies about the advantages and disadvantages of drinking. From time to time, various studies have appeared. Some say that drinking is completely harmful, while others say that a small amount of alcohol is beneficial to the body and there are many opinions. But one thing is for sure, a lot of drinking is certainly harmful, high concentrations of alcohol can lead to arteriosclerosis, increasing high blood pressure; not drinking is not harmful to the body.
