When is the best air every morning?

In fact, 10 is the best from morning to 2 pm.

In the morning, with the rising of the sun, the garden plants in the green space begin to carry out photosynthesis, absorb carbon dioxide and release oxygen, so the carbon dioxide content in the ambient air gradually decreases, reaching the lowest point around noon; In the evening, the photosynthesis of plants stopped and began to breathe, but because of the activities of urban people and the operation of vehicles, carbon dioxide was released into the air, and carbon dioxide in the air began to rise. Therefore, in terms of the freshness of ambient air, 10 is the best from early morning to 2 pm, but early morning is not the best time.

The air quality is the best from nine to ten in the morning. Because some time ago, floating objects in the air were settled due to dew or frost, and there were many pollutants in the air on the ground. Later, some waste gas or dust would pollute the air. Comparatively speaking, the air quality from 9 am to 10 should be the best.

Also, a little advice: if you exercise in the morning, don't exercise in foggy days.

I hope it helps you! O(∩_∩)O~
