In this episode we review what happens in dehydrtion, who may be at increased risk, and what happens to the body when it doesn't get enoug hwater. We also distinguish between two major types of dehydration; intracellular (without salt loss) and extracellular (with salt loss). Learn all about how this summer condition can lead to problems that feel as dangerous as being marooned on a desert isle!
