Be clever with water

Water may help you stay cool in more ways besides just drinking it. The neck, the armpits, and the groin area are the four main body areas where significant blood vessels are located near the skin's surface.

You can immediately chill down by using an ice pack or a cold, wet cloth in such areas. Emergency room doctors do this to treat heatstroke victims. On the back of your neck, even room temperature water is preferable to nothing. According to one 2015 research, applying cold packs on the cheeks, palms, and soles of the feet is also effective because these areas have blood vessels that don't contract when cold packs are used. Adding cold water to your hands and feet can help you cool off since their high surface area to volume ratio makes them more susceptible to heat loss.
