Relationship between physical health and physical exercise

Regular physical exercise can improve the function of the brain, on the one hand, by increasing the blood flow of the brain, on the other hand, by stimulating the synthesis of hormones and nerve development factors related to the formation of new nerve cells. Animal experiments have found that active animals have better memories and more cells in hippocampus. Exercise can also resist the occurrence of diseases, such as type II diabetes, which will increase the risk of dementia.
