Rescuers in Phoenix Are Using Mobile Cold Plunges to Save Overheated Hikers
Reported byOutside ↗·Sourced by Goodlede
The Phoenix Fire Department deployed mobile cold plunge devices to treat a hiker with heatstroke on Camelback Mountain on August 16, 2026, after medical crews confirmed she had a core body temperature at or above 104 degrees Fahrenheit and signs of altered mental state. The department now carries the portable devices on every spring and summer call after finding cold water immersion cools internal body temperature far more effectively than previous ice-pack methods.
Cold water immersion is established as the gold standard for exertional heatstroke treatment in medical literature; this article documents its practical deployment by rescue teams.
