Blood pressure can increase after exercise. Sympathetic excitement during exercise, the heart rate increases, the heart pumps more blood, and the pressure on the blood vessel wall increases, which can lead to an increase in blood pressure. However, long-term exercise can reduce body weight, reduce heart load, enhance heart rate per beat, reduce blood lipids, reduce the degree of atherosclerosis, and reduce peripheral blood vessel wall pressure, all of which will lead to a reduction in blood pressure. Of course there are many factors that affect blood pressure, including a healthy diet, a happy mood, and taking medication on time, all of which are important factors in controlling blood pressure.
