Pay attention to local air quality updates.
Recommended precautions you should take will usually be given in the form of advisories based on the latest air condition. So it is recommended that you keep track of the latest air quality update regularly. Here are some websites to check for the following countries:
- Canada: Air Quality Health Index
- Malaysia: Air Pollutant Index
- Singapore: Pollutant Standards Index | PM2.5 Readings
- United States: AIRNow
Avoid outdoor activities, especially outdoor sports.
Children, pregnant women, the elderly, and those suffering from chronic illnesses, especially heart and respiratory disease, should remain indoors when haze hits unhealthy levels. Healthy adults should avoid unnecessary outdoor activities. If you must exercise outdoor, avoid exercising in highly congested areas near busy roads and freeways, particularly during rush hours.
Close all windows, doors and any openings that may allow haze to enter your home and office.
Turn on the air conditioner if you have one. Note: If the weather is unusually warm, it can become dangerous if you stay indoor with no fresh air intake and no air conditioner. In this case, seek alternative shelter.
Use an air purifier to keep the particulate levels low.
Choose an air purifier that is suitable for the size and type of your home. Avoid air cleaners that generate ozone as they may generate more air pollutants. If you have multiple rooms, each room may need to be equipped with one air purifier to ensure the air is cleaned efficiently. Regularly replace the filters in the air purifier according to manufacturer’s instructions.
Drink more water and increase the intake of fresh fruits and vegetables.
They help the body to flush out toxins absorbed through the skin and lungs, and improve the immune system. Taking more anti-inflammatory fruits and vegetables also help to reduce inflammation that may be triggered by harmful fine particles in the air. Cut down on alcohol and coffee as they promote fluid loss and may leach nutrients from the body.
