In the long summer, you should go to bed early and get up early, and pay attention to yang, so as to better protect cardiovascular health. In particular, avoid sweating, because excessive sweating will lead to electrolyte disorder and damage the yang in the body. However, not exercising is not good for heart health. What should I do? The coolest time in summer is early morning. You might as well get up early in the morning and take a walk in the tree-lined flowers near your residence, which will help to relax your mood, promote the sublimation of yang in your body, promote blood circulation and enhance your metabolic function.
