Heat-related symptoms can set in quickly

MILWAUKEE - Being outside for even a short amount of time can be dangerous. We sent our Annie Scholz outside to find out how quickly your body can overheat.

With temperatures in the 90's, it's not just uncomfortable - it can be downright unhealthy.

"You have the chance of getting heat stroke, or you could get heat rash," says Kaizen Studio's Allison Schnelle. "I've seen people get heat rash where you get little bumps on your skin."

Schnelle is a personal trainer and says every extra degree puts you closer to the danger zone if you don't pay attention.

"The difference between 80 degrees and 90 degrees is really a big difference," Schnelle explains. "The humidity plays a really big role in that too. You're going to be sweating the second you step ouside."

So just how fast can the temperatures take a toll?

"You can be going out for an easy 20 minute run on a day like today and really the symptoms can start to kick in," says Schnelle.

We did a little experiment. We tested Annie’s skin temperature standing in Allison's air conditioned fitness studio - 93 degrees.

Then they stepped outside and got moving. 10 minutes of light jogging. A warmup on most days. But in this heat, it sent Annie’s skin temperature soaring to 106.

That's a 13 degree difference in just 10 minutes.

Annie’s internal temperature never reached a dangerous level. But if you start to get a headache or feel dizzy, those are signs of heat exhaustion which can quickly turn into heat stroke. That can be deadly. So make sure you have plenty of water with you over the next few days.
