Heat stroke is a medical emergency. Once with symptoms of heat stroke, individuals outside should be moved to a shady spot or indoors, and should lie down with their legs elevated. If able to drink liquids, they should also sip cool water.
For patients with heat stroke, it is most important to begin cooling their bodies right away; this could be done by removing their clothing, applying cool water to the skin, and fanning the individual. Ice packs could also be applied to the armpits, wrists, ankles, and groin. Finally, they should be brought immediately to the hospital after performing the aforementioned measures so they could receive further medical support.
