Quitting smoking can reduce blood pressure.

Blood pressure may decrease after quitting smoking, due to improved vascular endothelial function, improved blood circulation and reduced risk of cardiovascular disease. Blood pressure may decrease after quitting smoking, mainly for the following reasons. Improved vascular endothelial function: Smoking can damage vascular endothelial function, resulting in vasoconstriction and increased blood viscosity, thereby raising blood pressure. After quitting smoking, vascular endothelial function gradually improves, vascular dilation ability increases, blood pressure may decrease. Blood circulation improves: smoking slows blood circulation, increases heart burden, and leads to increased blood pressure. After quitting smoking, blood circulation improves, heart burden decreases, and blood pressure may decrease accordingly. Reduce cardiovascular disease risk: Smoking is an important risk factor for cardiovascular disease. Quitting smoking can significantly reduce the risk of cardiovascular disease. The reduction in cardiovascular risk also helps control blood pressure. It should be noted that the degree of blood pressure reduction varies from person to person, and the impact of quitting smoking on blood pressure may take some time to show. In addition, the overall health benefits of quitting smoking are not limited to lower blood pressure, but also reduce the risk of cardiovascular disease, cancer and other diseases, improve quality of life, etc. It is very important for people with hypertension to quit smoking. If blood pressure continues to rise or there are other health problems, it is recommended to seek medical attention promptly and follow the doctor's advice for treatment and management. At the same time, maintaining a healthy lifestyle, such as a reasonable diet, moderate exercise, weight control, reduce salt intake, etc., can also help control blood pressure and prevent cardiovascular disease. Special groups, such as pregnant women, nursing women, people with certain diseases, etc., should consult a doctor before quitting smoking to ensure the safety and effectiveness of the smoking cessation process. Doctors can provide specific guidance and advice on an individual basis.
