Proper and correct running will not accelerate one’s aging, but incorrect or excessive running will accelerate one’s aging. 1. Proper running has a delaying effect on aging. Running can increase the hormone secretion in the body, which can make the skin firmer and the body more youthful. Getting into the habit of running can strengthen the strength and flexibility of muscles and joints and exercise the cardiovascular system. In addition, exercise can promote skin microcirculation and metabolism, which can make the skin healthier. 2. Excessive running and incorrect running posture can cause physical injury and accelerate aging. If you run more than five times a week and more than 400 kilometers a month, your body will produce a lot of free radicals to reduce resistance and immunity; at the same time, friction of the meniscus may cause knee injuries, but also cause gastric ptosis, organ prolapse and other conditions. It is recommended not to run beyond your ability, and it is best to do so under professional guidance.
