Complete Guide
Why Singapore monitors haze
Regional fires can cause periods of smoky air in Singapore. Health effects depend on pollution levels, duration of exposure, exertion and existing health conditions, so advice should be tailored to the person and the current air-quality forecast.
Read PSI and PM2.5 correctly
The 24-hour PSI helps plan activities, while hourly PM2.5 readings can guide more immediate choices. Conditions change quickly, so a screenshot of yesterdayโs readings is not a safe basis for todayโs exercise or travel plans.
Protect higher-risk family members
Children, older adults, pregnant people and those with chronic heart or lung illness may need different exposure limits. Review official public-health guidance and consult a clinician for individual medical concerns.
Prepare indoor spaces without panic buying
Simple steps such as maintaining filters, reducing indoor pollution sources and creating a practical cleaner indoor room may help. Product claims about air cleaners and masks should be checked carefully; no single purchase removes every exposure risk.
Adjust work, exercise and school routines
Avoid rigid rules that ignore current conditions. Scale down or move strenuous activities indoors when official advice indicates, and follow schoolsโ or employersโ arrangements for outdoor programmes.
After haze conditions improve
Keep useful alert settings in place, maintain equipment and update household plans. For persistent symptoms or breathing problems, seek appropriate medical evaluation rather than relying on environmental readings alone.
Frequently asked questions
Are PSI and PM2.5 the same measure?
No. Singapore uses the 24-hour PSI forecast for planning ahead and hourly PM2.5 information to guide more immediate decisions, alongside official advice.
Should everyone wear an N95 mask for every haze day?
No. NEA and MOH advice varies with air quality, exposure, health status and activity. A mask is not a substitute for following appropriate activity guidance.
What if someone has breathing difficulties?
Seek medical advice promptly, especially if symptoms worsen or a vulnerable person is affected.
