Why it matters

Heat and particulate pollution can compound one another, increasing risks for people without air conditioning, outdoor workers, unhoused residents, and people with chronic conditions.

Who is affected

All residents, especially older adults, infants, pregnant people, outdoor workers, unhoused New Yorkers, and people with heart or respiratory conditions.

What happens next

The immediate measures ended as conditions improved. Health impacts, cooling-center attendance, mask distribution, and outreach still require evaluation.
