The place with the highest negative oxygen ions in Xishuangbanna

Xishuangbanna Dadugang Primitive Forest Park

Xishuangbanna Dadugang Primitive Forest Park has extremely high negative oxygen ion content, with an average of more than 10,000 per cubic centimeter and a maximum of 37,500. . This data far exceeds the World Health Organization's standard for clean air, which is 1,000-1,500 negative oxygen ions per cubic centimeter. Negative oxygen ions are considered to be "vitamins" in the air, which can enhance human body activity, improve human immunity, and degrade harmful substances in the air. As the only tropical rainforest in China recognized by the world, Xishuangbanna's air contains about 40,000 negative oxygen ions per cubic centimeter, making the place famous as one of the areas rich in negative oxygen ions.
