What irreversible harm can excessive fitness cause to the body?

Although excessive exercise brings us a lot of physical harm, I am not sure that it will not be irreversible. We all know that excessive exercise can make the heart rate unstable, reduce the immune ability and cause damage to the bones of the body.

There are more and more people exercising in today's society, but many people don't know that excessive exercise will bring great harm to themselves.

The first is that the heart rate will become unstable. The reason for this is that some beginners do not know how to proceed step by step and blindly pursue efficiency. This will make them lack oxygen and their hearts beat faster after strenuous exercise. So when we start fitness, we must do moderate exercise, not too much. However, the decline of immune ability brought by a lot of exercise is because when they do excessive exercise, cortisol is secreted too much in the human body. The long-term existence of this substance in any human body will destroy our immune system.

Finally, strenuous exercise has an impact on our bones, not to mention the direct impact of excessive exercise on our bodies. Excessive exercise will burden the bones in the body? . If our bones are overloaded, we will secrete the above cortisol. This substance will not only affect our immune system, but also have a negative impact on our bones? . It can decompose the bones in the human body, so long-term strenuous exercise will make our bones osteoporosis and even fracture.

Therefore, we don't need to do excessive exercise in a short time. Excessive exercise will only bring physical harm, just a kind of "self-harm". Standardized fitness is what we need.
