8 Things that Will Dehydrate You Fast

Your body is not ready for the heat

People who exercise in the heat have a more resistant body to higher temperatures. “People who exercise a lot and are used to functioning in a hot environment typically have good blood flow. They’ve trained their body to function during bouts of intense sweating and heat, and they also might be more cognizant of their hydration needs,” Goodson explains.

So, before exercising in the heat or choosing a vacation in a hotter climate, try to prepare your body for higher temperatures and don’t forget to drink plenty of water. Nonetheless, try to stop any activity if you notice certain symptoms of dehydration, such as dry mouth, muscle cramps, headache or dry skin.
