The so-called "oxidative stress" refers to the imbalance between oxidation and antioxidation in human body. If the human body is prone to oxidation, it will produce a large number of oxidation intermediates. With the more intense exercise, the oxidation of human body should be more intense, and the human body is easily oxidized. In short, walking hardly produces oxidative stress, jogging is gentle, and if you run fast, your body will respond to severe oxidative stress. If this reaction continues, the most serious result is diabetes. It can be seen that not all diabetics live in irregular houses.
