Dr. Natasha Withers: When the weather gets hot, your body usually cools itself by sweating. But in very high heat and humidity, sweating just isn't enough and your body temperature rises too rapidly. Dehydration and heat-related illnesses ranging from mild cramps to life threatening heatstroke may result. Here's how to heat-proof yourself so you can enjoy the summer.
Don't drink only when you're thirsty. During hot weather, you need to drink more liquid than the thirst indicates. In general, if you drink enough fluid so that you rarely feel thirsty and are producing colorless or light yellow urine, your fluid intake is probably adequate.
Check out the heat index which measures how hot it really feels with the humidity, humidity greater than 60% in your sweat evaporation and the body's ability to cool itself.
Head to air conditioning; with temperatures in the high nineties fans will not prevent heat-related illnesses. Air conditioning is the strongest protective factor. So consider visiting a shopping mall, movie theater or public library for a few hours.
Pace yourself. If you're exercising or working outside, limit the time you spend in the heat until you are conditioned to it. Take it easy. During the hottest parts of the day, dress right, wear lightweight loose-fitting clothing and a wide brim hat and make sure to use a sunscreen with SPF up to 30 or more.
So stay cool this summer. I'm Dr. Natasha, live well!
