[h=2]Heat Stroke[/h]Heat stroke is the most serious heat-related illness. It occurs when the body becomes unable to control its temperature: the bodys temperature rises rapidly, the body loses its ability to sweat, and it is unable to cool down. Body temperatures rise to 106°F or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not provided.
Signs and Symptoms of Heat Stroke
Warning signs vary but may include the following:
An extremely high body temperature (above 103°F)
Red, hot, and dry skin (no sweating)
Rapid, strong pulse
Throbbing headache
Dizziness
Nausea

Apparently, this couple died of heat stroke. My daughter experienced heat exhaustion, which is a milder form a couple of weeks ago.
Hi, I wanted to add a little bit of information to this thread that I just found. My husband and I live 45 miles from White Sands and moved to Las Cruces in 1989.
What I first noticed when I read about this tragedy was no one ever said anything about the temperature in the sun. The 100 degrees was the temperature we were registering in the shade that day, not the sun. The shade temperature today is 97 degrees so I just put the thermometer in the sun on the ground outside and within 10 minutes it was registering 123.5 degrees! I can barely make it outside to my mailbox daily and back (250 feet each way) in this heat!
We who live here know better than to go hiking when it's that hot anywhere in the afternoon and this is a long hike in the hot burning sun. Apparently the French couple did not realize this. I wish that they had been warned when they entered White Sands and had not been permitted to take this hike. It makes me very sad and I can certainly see why the couple didn't last long. I'm glad the boy survived though.
