Stay hydrated. Drink plenty of fluids even if you do not feel thirsty. You should minimize the amount of caffeinated beverages and alcohol that you drink, and grab a water bottle or a sports drink instead. A good test of hydration is to make sure that your urine is always clear in color.

Don't get too much sun. Sunburn makes the job of heat dissipation that much more difficult. Always remember to use sunblock (SPF 15 or greater) when outdoors for prolonged periods of time in the summer months, even on hazy or cloudy days. It is also important, if you have a loved one or friend who has memory problems, to ensure that he/she is not in the sun for any extended period of time. That person may not recognize or be able to tell you that he/she is uncomfortable.

Dress cool. Lightweight, light-colored, loose clothing reflects heat and sunlight, and helps your body maintain normal temperatures.

Anticipate change. Turn air conditioning systems or other ventilators on as soon as you go inside and take off extra layers of clothing when going outside. For seniors having trouble recognizing temperature changes, these automatic actions help maintain a comfortable indoor and outdoor environment.
