When the summertime heat is turned up, some of us are more at risk than others.
"What happens with normal aging is that you actually have less water in your body and you’re more at risk for dehydration. The other thing is that elderly individuals, they don’t sweat as much, so they’re more likely to develop a higher temperature, and hyperthermia and heat stroke," said Dr. Ronan Factora, of the Cleveland Clinic.
He said signs the heat may be getting to a person include dizziness, weakness, and confusion. Dark-yellow urine is also a sign of dehydration.
"Make sure that you drink at least 6 to 8 eight ounce glasses of water a day on a regular basis or if the temperature is higher or you’re spending a lot of time outdoors or if the air conditioner is not on, make sure you’re drinking plenty and plenty of fluids," he said.
