Heat Relief Regional Network


The Heat Relief Network is a regional partnership of the Maricopa Association of Governments (MAG), municipalities, nonprofit organizations, the faith-based community, and businesses. Each year, MAG coordinates the mapping of the Heat Relief Network, a network of partners providing hydration stations, refuge locations, and water donation sites throughout the Valley with the goal of preventing heat-related and heat caused deaths among vulnerable populations and people experiencing homelessness.

Tips to Avoid Heat-Related Illness

  • Increase fluid intake regardless of activity level. Staying hydrated is extremely important.
  • Limit exercise or outdoor activity between the hours of 11am and 3pm.
  • When outdoors, wear a sunscreen with a minimum SPF 15 and re-apply often. Wear a hat, lightweight clothing and sunglasses.
  • Rest frequently in shady or cool areas to give the body's temperature a chance to recover and cool down.
  • Never leave infants, children or pets inside a parked vehicle.
  • Respectfully check on elderly neighbors to make sure their air conditioning is working and in use. Take advantage of free air-conditioning by visiting locations like shopping malls, the library or other heat refuge locations provided on the map.
