Outdoor workers are a sensitive group: avoid long or intense outdoor work.

باہر کام کرنے والے حساس افراد میں شامل ہیں: باہر لمبا یا سخت کام نہ کریں۔

  • Move heavy tasks to a better time, or indoors, if you can.
  • If the work cannot move, keep it short and less intense, and take more breaks.
  • Watch for coughing or shortness of breath. With heart disease, palpitations or unusual tiredness need a doctor.
  • اگر ممکن ہو تو بھاری کام بہتر وقت پر کریں یا اندر منتقل کریں۔
  • اگر کام نہیں ہٹ سکتا تو اسے مختصر اور ہلکا رکھیں اور زیادہ وقفے لیں۔
  • کھانسی یا سانس پھولنے پر نظر رکھیں۔ دل کے مریض کو دھڑکن تیز ہونے یا غیر معمولی تھکن پر ڈاکٹر سے رجوع کرنا چاہیے۔

Checked against Punjab EPD's official daily AQI

No comparison has been run yet.

How it works. Every hour a pipeline collects readings from Lahore's monitors, weather, satellite estimates and fire detections, checks and cleans them (every fix is logged), and a model forecasts the next 24 hours with a likely range. The advice follows the US EPA guide, which lists outdoor workers among the groups most exposed. The question box (answers with citations, or “I don't know”) runs in the team's local app because it needs a server.
