Many citizens have a good habit of doing morning exercises, but some people think that the earlier they do morning exercises, the fresher the air, the better the effect, especially going to parks and Woods is equivalent to taking oxygen in a free oxygen bar. In fact, doing morning exercises in the park before sunrise is one of the misunderstandings of morning exercises, which not only fails to achieve the expected results, but may damage your health.

The highest concentration of pollutants is before sunrise.

Many middle-aged and elderly people like to exercise in the park before dawn or sunrise. Such morning exercisers generally think that the earlier they exercise, the quieter the environment and the fresher the air than many people, but it is not. At night, the air near the ground will cool down, which is easy to form a stable inversion layer, and the pollutants in the air are difficult to spread, and the pollutant concentration reaches the highest before sunrise. At the same time, plants can't carry out photosynthesis before sunlight, so they emit carbon dioxide instead of oxygen, and the content is also the highest in a day. If you come out to exercise at this time and inhale carbon dioxide and pollutants, the morning runner will not only have little exercise effect, but also be top-heavy and weak.

Therefore, the doctor reminds that people who take part in morning exercises should choose after sunrise, preferably from 6 to 9 o'clock. Because the inversion layer was destroyed at that time, pollutants spread outward, and sunlight also made park plants begin to discharge oxygen.

Remind you: this remedy comes from the internet before sunrise, please follow the doctor's advice before using it.
