Doctors are urging people to be aware of the possible signs of heat stroke as feels-like temperatures climb to near 100 degrees.

Symptoms of a heat stroke include:

-A throbbing headache

-Nausea and vomiting

-A rapid heart beat -- and you may lose consciousness

Doctors say if you feel any of these things or see someone having a heat stroke call 911.

To avoid heat exhaustion, doctors advise staying in cool air-conditioned places, drinking plenty of water and taking a cool shower or using cold compresses to help cool you down.
