[1][2] Cooling centers are one of the possible mitigation strategies to prevent hyperthermia caused by heat, humidity, and poor air quality.
[3][9] Cooling centers may also be used in places like Portland and Seattle where home air conditioning is rare but summer can bring temperatures exceeding 90 °F (32 °C) for several days.

Cooling centers provide shade, water, and restrooms; medical attention and referrals to social services may also be offered.
