Soaring Temperatures Increase Risk of Heat-related Illness
With Madison-area temperatures expected to soar through the 90s on their way to close to 100 degrees this week, a UW Health emergency medicine physician says make sure you think about your health when you're enjoying the summer sun.
The combination of high temperatures and high humidity increase susceptibility to sunburn and dehydration, the ramifications of which are relatively less severe, but also to heat exhaustion and heat stroke, which can be at the very least unpleasant and potentially life threatening.
Dr. Allan Mottram says the symptoms of heat exhaustion - a depletion of the body's water and/or salt resources - include feeling overheated or lightheaded, fatigue and nausea.
"With heat stroke, which is the more severe form," he continues, "people are dehydrated to the point they're not sweating and their temperatures are elevated to a dangerous point. They can become confused and even unconscious."
But you can take steps to prevent heat-related ilness. Here's what Dr. Mottram recommends.
- Keep an eye on the reported heat index, which can be found on a number of online weather sites and is often broadcast on the local news. If it's 90 or more, conditions are ripe for heat stroke and heat exhaustion.
- Avoid prolonged exposure to the heat and sun. If you're outside, seek out shady areas for protection and identify public spaces with air-conditioning as places of refuge from the heat.
- Stay hydrated. Drink enough water, both before you go outside and when you're exposed to heat.
- Limit your strenuous activities, and be smart about those you can't avoid. "If you're doing something like mowing the lawn," says Dr. Mottram, "plan to do those things in the morning or evening, not in the middle of the day."
