April 14, 2017

As the population ages, a growing number of people become more vulnerable to extreme summer heat. In 2003, a heat wave was blamed for 14,800 deaths in France.

Older people are also more likely than younger folks to be taking medications that cause fluid loss (and therefore dehydration), including some laxatives, furosemide (Lasix) to counteract water retention, and other diuretics for blood pressure control.
