Exercise can change the vascular network of the brain. When the human body is in a state of exercise, the blood flow of the body will increase, and the blood flow of the brain will also increase, which will lead to an increase in the content of a vascular specific molecule called vascular endothelial growth factor (VEGF). This process will promote the formation of new blood vessels in hippocampus. In the brain of rodents, nerve regeneration and angiogenesis are interrelated, and the potential reason may be that new blood vessels bring more growth factors to this brain region. Research shows that weightlifting and high-intensity interval training are also good for the body. Julia Basso, a senior researcher in the Department of Human Nutrition, Food and Sports at Virginia Tech University, said: "People who gain the most from exercise have the greatest improvement in their cognitive ability, which means that high-intensity exercise can also improve their cognitive ability. However, regardless of the intensity of exercise, it will make people feel better. "

"Going out for a walk can make you feel better, but if you want to improve your cognitive ability, you need to do more intense exercise." "High-intensity exercise is conducive to maintaining long-term personal health and improving long-term cognitive ability."

If you just get into the habit of exercising, or because of age or injury, you can't take part in some strenuous exercise, you can choose to take a walk, which is also good for your health. The most important thing is that you have found something you like to do and will stick to it.
