Advice

When the concentration dust particle levels of are high, South Korean health authorities typically advise residents and visitors to stay indoors as much as possible, to close windows, and to drink plenty of water, especially the elderly and those with respiratory problems. Individuals currently in South Korea are advised to follow local media reporting and the Korean Meteorological Service website for the latest information.
