My mom (65 yrs. old, healthy w/ asthma) had an episode in August that she describes as heat stroke
/dehydration - exposed to warm weather and not much to drink. That night, for a couple hours, she was super overheat
ed and couldn't get her body to cool down. She finally cooled herself off by using cold, wet wash cloths on her head and upper body. Others in the house were comfortably sleeping under their covers, so the house wasn't overly warm at the time.
