Northern California is setting heat records this week, and hot weather is on its way to the rest of the country. That doesn’t mean you shouldn’t exercise, but be sure to drink plenty of fluids. Consider moving your workout to the evening or early morning. Rest and cool down if you start to feel uncomfortable. If you are working out in a hot place — or with someone else who is — be alert to these more serious signs from the American College of Sports Medicine and the Red Cross.
Heat cramps are painful muscle spasms that result from overheating. They usually occur in the legs and abdomen.
