Everyone knows that consistent exercise helps prevent and control many chronic diseases, such as hypertension, diabetes, and obesity. However, too strenuous exercise can also bring fatal hazards, such as aortic coarctation. Excessive exercise can lead to increased blood pressure The average blood vessel consists of three layers: the inner membrane, the middle membrane and the outer membrane, and the three layers fit closely together. In some special cases, high velocity and high pressure blood flow can tear the inner membrane and impact the middle membrane, causing blood flow to enter between the middle and outer membranes, forming an entrapment. If the entrapment is not treated in time, the outer membrane is broken by the blood flow and can lead to intracavitary hemorrhage, which can be fatal within minutes. One of the most important causes of aortic coarctation is high blood pressure. This high blood pressure is not only narrowly defined as hypertension, but excessive and intense exercise and overly strong emotions can lead to increased blood pressure. Exercise is not the more intense the better In addition, there are people who believe that they are not well because of the presence of harmful substances in the body and need to rely on intense exercise and sweating to detoxify the body, such an understanding is one-sided. In fact, in many games, in addition to the blood pressure increase brought about by exercise, high excitement and emotional excitement can also cause a rise in blood pressure. Therefore exercise and exercise should not only be in the right amount, but also at the right time and in the right amount.
