MILWAUKEE -- Being outside in the heat is no joke. Bell Ambulance saw an increase in calls Saturday. 30 percent more than a typical Saturday.
Eighty-five paramedics were on the clock. Most of the calls they answered were related to heat exhaustion.
Signs of heat exhaustion include: muscle cramp, dizziness and vomiting, but if the symptoms get worse, first responders said call 911.
"You might get a bad headache. You're going to stop sweating and your skin will turn red then you're getting into heat stroke. That's a medical emergency," said Scott Michelson with Bell Ambulance.
The message from paramedics is simple: drink lots of water, don't stay in the heat too long and cool off in a pool.
