As we all know, fitness can make us healthy. Although moderate fitness can keep us healthy, excessive fitness will bring a lot of harm, which will not only make people uncomfortable, but also bring health risks, which is really not worth the candle.

Excessive exercise makes people mentally dependent. A lot of exercise will increase the release of morphine, which will be released into the blood in large quantities, which will make people feel excited and become addicted over time. This substance causes people to be very excited when they exercise, but once they stop exercising, they will soon start to feel anxious and depressed.

Excessive exercise may make people more likely to get sick. After strenuous exercise or long-term exercise, the body's immunity will be reduced. When the immune ability is reduced, it is easier to get sick when attacked by germs and viruses. So although exercise is a good way to exercise, once you don't control the amount of exercise, you will put yourself in a health threat.

Excessive exercise may also make people more vulnerable. Because after a long period of exercise, people's central nervous system is very tired, and the function of cerebral cortex declines, athletes will show slow response. If you continue to exercise at this time, you may get hurt. So, don't bite your teeth and stick to it after you feel tired. Appropriate relaxation is also necessary.

Nowadays, more and more people exercise through fitness, and want to build muscles to shape their bodies, so that they can be healthy and look better. However, excessive fitness will be harmful to health, so everyone should exercise step by step and do what they can, you know?
