With temperatures in triple digits in the Wenatchee Valley, prolonged time outside in the sun could result in dire consequences.

Cascade Medical public relations director, Clint Strand says stay inside with AC and crank the fans on high blast.

"If you take prescription diuretics, antihistamines, mood-altering drugs or anti-spasm drugs, the heat can affect that. Make sure you ask your doctor about the effects of sun and heat exposure. If you need to go outside, let's face it, the water will not garden itself, plan to do those activities in the morning or the evening. Midday is no time to be watering your plants."

He also encourages folks to check on family and friends that are vulnerable in extreme heat.

Strand says if you do go outside, stay hydrated with water and avoid consuming alcoholic beverages, caffeine or drinks with lots of sugar.

"Did you know that if you close the windows that get morning or afternoon sun, you could decrease the amount of heat that enters your home by as much as 80%. Awnings, those huge umbrellas that you can stick outside your window or blinds, use them. Make sure that the morning or afternoon sun does not head into your house."

The National Weather Service has issued an excessive heat warning with temperatures expected to 100 degrees for at least the next week.
