Heat Stroke & Heat Exhaustion
Heat exhaustion is when the body becomes dehydrated, mostly from sweat due to the dog-gone heat! Heat stroke is when the body’s core temperature rises to above 105 degrees Fahrenheit. After about 30minutes basically the brain and other internal organs get fried from this elevation in temperature.
Sweating is the #1 way to cool the body down. However, when the relative humidity outside is great than 75%, sweating doesn’t work well. And when the temperature outside is greater than 90 degrees Fahrenheit, the body doesn’t cool off well. So these factors can lead to overheating of the body.
Heat exhaustion symptoms include: lowered blood pressure, lightheadedness, irritability, headache, nausea, fatigue, muscle aches, and hyperventilation.
Heat stroke symptoms include: delirium, losing consciousness, shortness of breath, and excessive bleeding. Heat stroke tends to occur in young healthy people who don’t sweat during exercise on a hot, humid day.
Treatment of heat exhaustion and heat stroke include: get out of the sun, get out of the heat, drink cool fluids, and even ice but don’t induce shivering will increase body temperature. CPR might be needed. Call 911.
Sweaty, sweaty, sweaty. Ooh, it is summertime and it is hot. But all this sweating and heat can cause heat exhaustion, or worse yet heat stroke. So this morning I got up to do the news, not realizing it was the 4th of July — I could have slept in. Such is life. So I hope you watch the video to see ALL MY HARD EFFORTS this holiday morning. Now it is time to baste the ribs on the grill. We are grilling for 8 hours to get it smoky and just right.
