As we adapt to the heat, our sweating becomes more efficient and our sweat becomes less salty because the body is preserving its salt stores. Even after your body has acclimated, you can make yourself (and your sweating) safer:
Drink lots of fluids before, during and after exercise.
Don’t be quite as standoffish with the salt shaker.
Wear moisture-wicking, baggy clothing.
Avoid direct sunlight.
Wear a hat and sunglasses.
Check your medications. Some drugs can limit the ability to sweat. They can include those for motion sickness, cardiac conditions and gastrointestinal upsets. Ask your doctor, who may either recommend another type or suggest you ease the intensity of your workouts.
Beware humid days. You sweat, but your skin can’t dry any easier than a towel hanging on a cloudy-day clothesline can. Drink extra fluids when it’s humid.
If you feel weak while working out, stop. Hydrate with a drink that contains some sodium. The general rule is 3 to 8 ounces every 10 to 15 minutes while you exercise. Chocolate milk is a good choice. Have a banana for carbohydrates and some chicken for protein.
