It is July in Texas and it's hot. So you're probably thinking why is the National Weather Service telling us about the heat? Well, it's simple: heat kills. Know the signs of heat exhaustion versus heat stroke. Faint or dizzy with excessive sweating, that's heat exhaustion. Get to a cooler place and drink water. What if you or someone you know, is in the heat and suddenly stop sweating, get a throbbing headache and/or nausea? Well, these are signs of a Heat Stroke and this is an emergency situation. Your body is no longer able to cool off and if you don't get immediate care---it can be potentially fatal. If you're suffering from Heat Stroke, you should call 9-1-1 and then immediately take action to cool down. as you wait for help to arrive.
