Four. Morning exercise is the most afraid of early
In summer, it is early in the morning, and many people arrive early Morning exercise in the park. But the summer climate is sultry, and in windless weather, air pollutants are generally not fully diffused before 6 am. In addition, before sunrise, because there is no photosynthesis, not only there is not too much fresh oxygen near the green plants, but a large amount of carbon dioxide is accumulated, which is not good for health. Therefore, the summer morning exercise time should not be earlier than 6 o’clock.
V. The worst fear at home < /strong>
Summer is hot and humid, which makes it easier for dust to adhere to the air and enter human skin and body. Because it is difficult to detect with the naked eye, people often neglect to clean them up. They float in the air for a long time and adhere to the surface of objects in large quantities, becoming the habitat of dust mites and mold spores in the air. These dirty things will take the opportunity to enter the respiratory system, and then cause various diseases such as asthma and rhinitis. It is suggested that the frequency of cleaning should be increased in summer, once every two or three days.
