High blood pressure should not drink and smoke. Alcohol contains a lot of ethanol content, and ethanol enters the body under the action of ethanol dehydrogenase, it will produce acetaldehyde, which can stimulate the body’s vascular tissue, which leads to vasoconstriction, causing the risk of further increase in blood pressure. Therefore, it is recommended that hypertensive patients avoid alcohol in their daily life to reduce the risk of elevated blood pressure. Tobacco contains a large amount of nicotine and tar, which can stimulate the endothelium of human arteries and cause excitation of the sympathetic nervous system, which may lead to an increase in blood pressure. If smoking for a long period of time, it may also cause damage to the endothelium of the arteries, inducing the phenomenon of atherosclerosis. Therefore, smoking and alcohol may stimulate the blood pressure of hypertensive patients to rise further, so hypertensive patients should avoid smoking and drinking as much as possible in their life. It is recommended to control blood pressure under the guidance of a physician and quit smoking and drinking.
