Be aware: Symptoms related to dehydration, heat exhaustion and other heat-related injuries include: becoming weak feeling cold and clammy having a dry mouth feeling dizzy or faint passing out (in extreme cases) when it comes to safety tips, gupta suggested keeping it simple: stay hydrated and drink fluids throughout the day wear loose-fitting clothing.

Know (T)hy Dration!: The brain is really good at keeping our body temperature within a very narrow range. When the air temp is high, the brain cools the body using sweat. Of course, for this cooling system to work optimally, it's especially important to drink plenty of water. It sounds like knowing about dehydration -its signs & symptoms- as well as how specifically to prevent it might help: http://bit.Ly/12mh9lu.
