CHICAGO — This week's heat wave may be uncomfortable, but you're healthy, active and feel just fine. So what if you're over 65? Think again. Feeling good doesn't mean you're safe.

There are changes in an older person that raise the risk for heat stroke and other problems. An older body contains far less water than a younger one. Older brains can't sense temperature changes as well, and they don't recognize thirst as easily.

Blistering summer heat is an underappreciated killer, claiming by some estimates as many as 1,000 U.S. lives each year — more than any other type of weather.
