Health recommendations
The Bangkok Air Quality Information Centre stated that air quality is at an orange level, meaning it is beginning to affect health.
For the general public, recommendations include using personal protective equipment such as PM2.5 masks every time they go outside, limiting the duration of strenuous outdoor activities or exercise, and watching for unusual symptoms such as coughing, difficulty breathing, or eye irritation.
Vulnerable groups were advised to use personal protective equipment every time they go outside, avoid strenuous outdoor activities or exercise, and follow their doctor’s advice. Those experiencing unusual symptoms were advised to seek medical attention immediately.
The centre added that when air quality reaches a red level, it will have a health impact. In such cases, all individuals are advised to avoid outdoor activities. If outdoor activities are unavoidable, personal protective equipment such as PM2.5 masks should be used at all times. Individuals with pre-existing medical conditions were advised to stay in areas safe from air pollution, have necessary medications and equipment ready, and strictly follow their doctor’s instructions.
Earlier this week, the centre reported more than 20 districts exceeding the standard level, with Pathum Wan previously topping the list with 49.9 µg/m³.
