HOUSTON - With a Dallas toddler and a Pennsylvania four-year-old girl dying in hot cars this past weekend, the death toll for kids in hot cars is now 21 this year alone!

"A child should never be left in a vehicle, at all, not for any amount of time in this sort of heat," said Steffanie Campbell, doctor of internal medicine at Kelsey-Seybold Clinic.

She says within seconds the child in your car is at a high risk for a heat stroke.

But the extreme heat doesn't only effect kids. The National Weather Service says 45 people died of extreme heat last year.

"The first warning signs that you're starting to get into heat exhaustion are dizziness, light-headed, fast heart rate or palpitation, nausea and feeling weak or tired," said Dr. Campbell.

Be careful out there and don't take the heat lightly.
