How does PM 2.5 harm the body?

      PM 2.5 dust is small dust with the size of about 1 in 25 of the diameter of a hair. Because it is very small, it escapes the filter from the nose and can pass down to the alveoli when we inhale. The horror of this dust is that it activates free radicals, reduces antioxidants, disturbs the body's balance and activates genes involved in the secretion of inflammatory substances that are very harmful to our body tissues.

• Encourage people with chronic respiratory diseases to exacerbate symptoms such as allergic rhinitis, asthma and emphysema.

• Encourage people with chronic cardiovascular disease to have exacerbations, especially myocardial ischemia.

• Long-term effects will deteriorate lung function, possibly cause emphysema even without smoking and increase the chances of lung cancer.

      PM 2.5 is particulate matter that has a negative impact on the body and tends to occur every year, so we must take care of ourselves and stop polluting behaviors. Most importantly, don't forget to wear a mask that can filter PM2.5 every time before leaving the house. with best wishes from Chiangmai Hospital
