Keep the sun off your skin as much as possible. Actually wear more clothing consisting of loose fitting breathable fabric.
Run cold water on your wrists every hour
Use covers at night with a hot water bottle filled with ice water. Put it behind your ankles or knees.
Put an ice pack under your left arm. Close to the heart.
Wear cooling bandanas around your neck(carotid artery)
The point is to keep your major pulse points cool
Or be like me~sit your butt in the airconditioning or right in front of a fan with a nice cool drink:) Being out in this kind of weather will cause wrinkles girls!! Hot sun is VERY bad! Bad, I say!
