If you happen to live in any of the 48 contiguous US States, you’ve probably experienced this summer’s record HEAT WAVE. Temperatures have broken records nearly everywhere. In New York City alone on July 22d, the temperature in Central Park recorded 105 degrees, w/ a Heat Index of 116 !!. Similar or worse conditions showed up in the South, Southwest and Midwest. For many people, especially the elderly and very young, knowing how to keep from getting Heat Stroke or exhaustion is an unknown. Here are a few tips on how to avoid getting sick—either Heat Stroke, Heat Exhaustion or worse.

Several terms should be in your thoughts and actions during these periods: HYDRATION (Drink plenty of water; a minimum of 2 qts per day depending on your age and level of activity—one’s urine should be pale yellow, an indication that you are getting a sufficient amount) . A number of studies have shown that DE-Hydration impairs Brain Function and working memory–that is, the ability to actively hold information in the mind needed to do complex tasks such as reasoning, comprehension and learning. Measure of tension and anxiety were also greater.

Keep physical activity to a minimum……and do your workouts early in the morning or around sunset….

To your Health,
