It's Hot Out There
We're having a heat wave. It was 106 degrees in my neighborhood today, and I saw a jogger running at 2 pm. This is not advisable. Two thirds of the heat generated during exercise is converted to an inner source of heat which contributes to heat injury. Heat stroke refers to body temperature above 105 degrees and it is associated with mental status changes such as loss of consciousness or coma. However prior to onset of heat stroke, there may be nausea, dizziness, headache, and difficulty with speaking or walking.
Treatment of these symptoms known as heat exhaustion, involves fluids, sprinkling water and fanning the patient, and applying ice packs to the head, neck, abdomen, groin, and under the arms. If there is any evidence of heat stroke then it is an emergency, and the patient needs medical attention immediately. Remember to stay well hydrated. Don't wait until you're thirsty before you drink water.
