What are negative ions?
People will feel dizzy after staying in a closed room in the city for a long time. When we come to places such as forests, seasides, waterfalls, etc., we will feel refreshed. This is the effect of negative air ions. Negative air ions, also called negative oxygen ions, refer to negatively charged oxygen ions that have gained excess electrons. It is formed when oxygen molecules in the air combine with free electrons. Natural discharge (lightning) phenomena, photoelectric effects, fountains, waterfalls, etc. can ionize the surrounding air to form negative oxygen ions. Negative oxygen ions enjoy the reputation of "air vitamin" and "longevity element" in the medical field.
