Blood pressure will rise in a short time after exercise, mainly including two reasons, namely, sympathetic excitation, increased hormone release, as follows: 1, sympathetic excitation: due to exercise sympathetic excitation, cardiac output increases, circulating blood volume increases. 2, increased hormone release: exercise will lead to the body of the hormone that elevates blood pressure increase in the release of the hormone. Elevated blood pressure after exercise is a temporary phenomenon, after rest will soon be restored. Due to the large amount of sweating during exercise, if you do not replenish water in a timely manner, it may lead to a decrease in blood pressure due to insufficient blood volume. Therefore, it is necessary to replenish water in time after exercise to avoid the occurrence of low blood pressure due to insufficient blood volume. In general, you should exercise reasonably, and reasonable exercise is very beneficial to your health.
