Extreme heat is expected to affect 3.5 billion people by 2050 as the climate crisis escalates.

Hotter temperatures increase air pollution, which can exacerbate health issues like asthma or even heart disease.

City residents are high risk because surfaces like pavement and concrete absorb heat and tall buildings block air flow.

Low-income communities and communities of color, as well as other vulnerable populations, are also at higher risk.

But there are strategies to help you stay cool.

Eat light summer meals that don’t require cooking. Salads, fruits, and sandwiches are great options!

You’re more likely to have symptoms of heat stress when dehydrated. Drink water before you even get thirsty.

Apply damp washcloths to places like your neck and forehead to cool down quickly.

Check in on yourself and others! Symptoms of heat illness include dizziness, paleness, weakness, nausea, or a rapid pulse.

Close your blinds and shades when heat is at its peak (around 3 pm).

Go to a park! Leafy public parks offer relief from the sun, as trees and vegetation reduce the urban heat island effect.

Advocate for equitable access to parks. Support initiatives that improve funding for green spaces in park-poor communities.

Support your community by pushing for local climate adaptation initiatives, like green-roof programs.
