EMS: This kind of heat prompts more 911 calls

Jeff Hammerstein from the Wake County EMS says his station receives more calls in this kind of heat.

"We know when we get a heat wave like this, we are going to see an increase in calls," said Hammerstein. "Quite often, it is young, healthy adults that are out doing exercise or work through the course of the summer heat."

The best way to prevent heat exhaustion?

Drink water and "use your head," said Hammerstein.

"Everyone is susceptible to this, it doesn't matter how healthy you are," he said. "This can get everyone and you've got to take precautions. It's preventable."

According to Hammerstein, everyone needs to make sure they drink water before going outside and take frequent breaks during outdoor exercise.

Some people have to work outside, and Hammerstein said it's up to their supervisors and managers to make sure crews are not going too long without those breaks. "You just can't go too long outside without taking a break," he said.
