The drop in blood pressure after exercise is mainly due to peripheral vasodilatation and is also related to a decrease in the strength of the heart’s contraction. Human blood pressure generally fluctuates, when factors such as exertion, exercise, eating, and the environment are involved, blood pressure changes. A drop in blood pressure after exercise is usually caused by excessive exercise, resulting in peripheral vasodilatation. Although the blood pressure may drop, it is within the normal range and is usually not lower than normal. Even if it is lower than normal, it is physiologic hypotension and can be recovered after a period of time. Secondly, the human body during exercise due to the heart contraction force strengthened, there will be a rise in blood pressure. However, after resting for some time, the blood pressure will drop, which is related to the reduced strength of the heart’s contraction and is a normal situation. If the drop in blood pressure is accompanied by symptoms such as dizziness, nausea, blurred vision, etc., more attention needs to be paid and it is recommended to go to the local hospital for relevant examinations.
