On the other hand, air pollutants are the most difficult to diffuse before 6 am in summer, which is often the peak period of pollution. People generally like to do morning exercises in lawns, Woods, flowers and other places where green plants grow. Before sunrise, because there is no sunlight to make plants photosynthesis, there is not much fresh oxygen near green plants, but a lot of pollutants are accumulated, which is obviously unfavorable to human health. Therefore, the time for morning exercise in summer should not be earlier than 6 o'clock.
In short, there is no need to hurry for morning exercises.
Warm reminder During exercise, the whole body blood is redistributed, gastrointestinal peristalsis is weakened, and the secretion of various digestive juices is greatly reduced. Therefore, if you eat immediately after exercise, you are prone to gastrointestinal diseases such as indigestion.
