1/30th of fine dust in hair, how to deal with it?

Heavy metals in fine dust contain harmful substances such as iron and cadmium, which can penetrate the lungs through the respiratory tract and cause various diseases such as cardiovascular disease. In particular, ultrafine dust is very small, about one-thirtieth the thickness of a hair, and can penetrate deep into the lungs and affect various organs and brains such as respiratory and cardiovascular systems.
Choi Joo-hwan, a professor of respiratory and allergy at Korea University Guro Hospital, said, `Long-term exposure to fine dust increases abnormal inflammatory reactions in the airways, which leads to a decrease in lung function and a higher likelihood of worsening symptoms such as shortness of breath and coughing.' In particular, patients with airway diseases such as asthma and COPD (chronic obstructive pulmonary disease) need to be careful about outdoor activities because hospitalization due to acute inflammatory reactions increases.'
Elderly people, children, and pregnant women who are vulnerable to fine dust are particularly exposed to greater risks. Elderly people have weak immunity, which can worsen cardiovascular and respiratory diseases caused by fine dust, and children can react sensitively to fine dust because their respiratory systems are not fully developed. Pregnant women should minimize going out and thoroughly manage their health as long-term exposure to fine dust can negatively affect the fetus.
Professor Choi Joo-hwan emphasized that `If you have to go out inevitably, you should wear a mask that has the effect of blocking fine dust.' After going out, it is recommended to take a shower and shake off your outdoor clothes before entering the house to block fine dust from entering the room.
On days when fine dust is severe, you should refrain from intense exercise. This is because exercising increases breathing volume, allowing ultrafine dust to penetrate deep into the lungs. Therefore, it is preferable to exercise lightly indoors rather than outdoors.
It is recommended to manage air quality indoors by using an air purifier, and ventilation is short and frequent by selecting a time zone with relatively low fine dust concentration. The vents connected to the outside should be kept clean to prevent contaminated air from entering the room.
