Air pollution is not just about coughing, sneezing, and dry eyes! It’s been good for so many years. People living in the big city can't help but have similar ideas. However, the seriousness of air pollution is definitely not because of “habits”. Can turn a blind eye. The World Health Organization (WHO) pointed out that air pollution is an important cause of a series of health problems such as respiratory infections, heart disease and even lung cancer. There are about 3.1 million people who die prematurely due to air pollution every year in the world, accounting for 3.2% of the deaths due to illness . However, recent studies have shown that long-term breathing of dirty air not only damages heart and lung function, but your intelligence will also drop!
Last year, Laura Fonkon, a Ph.D. student at the Ohio State University's Neuroscience Institute, and a Davis Heart and Lung Research Institute collaborated on a mouse experiment. The researchers asked a group of mice to breathe polluted air - simulating human environmental pollution; the other group breathed filtered fresh air; 6 hours a day, 5 days a week, for a total of 10 months, can be said to run through the mice Most of the "rats". Afterwards, the researchers used a five-day experiment to train all older mice to find a small hole in the dark box from a very bright field within 2 minutes (the black box is the favorite place for mice) . It was found that mice that inhaled polluted air for a long time not only needed more time to learn to find a hole, but also forgotten it very quickly.
According to the anatomical results, the hippocampus of the two groups of mice [Note 1] showed significant differences. The neuronal dendrites in the hippocampus of contaminated mice [Note 2] are shortened, the spinous processes on the dendrites (structures used to receive signals) are reduced, and the complexity of the cellular structure is insufficient. Previous studies have shown that these changes are closely related to the decline in learning and memory.
The Davis Institute also found that suspended particles in polluted air  cause systemic inflammation, pro-inflammatory cytokines are particularly active in the hippocampus, and the hippocampus is particularly sensitive to inflammatory damage - the result can be imagined Know. In addition, systemic inflammation is also prone to depression, which is also reflected in another Laura experiment. This experiment first revealed the direct damage of air pollution to the brain. The results were published in the July 2011 issue of Journal Molecular Psychiatry .
How do we protect ourselves from air pollution?
Probably no one wants a few years later, when your smart and lovely grandchildren enthusiastically teach you to use the latest generation of high-tech products, you can't even figure out where the switch is. Although the complete resolution of environmental problems depends on the entire society, national policies and regulations and advanced technology, we must take the initiative to defend ourselves and minimize the risk of air pollution:
1. Develop a good habit of checking air quality and adjust the timing of outdoor exercise or walking according to the quality report.
2. Under normal circumstances, the higher the temperature during the day, the worse the air quality. So try to arrange outdoor activities in the morning and evening, avoiding the noon time (of course, it is also good for sun protection);
3. Try to avoid busy streets when walking;
4. Turn on the air filter when driving. If possible, use a HEPA filter (High Efficiency Particulate Air Filter) to help filter out very fine suspended particles;ALONDES High Efficiency Particulate Air Filter helps to clean up air pollution
5. Regularly replace the air conditioning filter;
6. Keep the room dry and avoid mildew - mold will also float in the air and be inhaled by you;
7. Less places to "swallow the clouds and spit";
8. If the air is really bad, you have to walk on the road for a long time, you must wear a mask! [4-6]
Finally, is it planned to go where to go to care?
