Lots of high temperatures and humidity across Texoma this week, and doctors are warning you to stay safe in the heat.
Medical professionals say hydration is the best thing you can do to prevent heat exhaustion. You should drink lots of water, even if you're not thirsty.
It could take up to a week for your body to adjust to when temperatures spike up.
Heat exhaustion is what happens before a heat stroke, which they say is the most severe heat illness.
Doctors say symptoms of heat exhaustion are nausea, vomiting, dizziness, and profuse sweating.
"So the first thing you want to do is get them out of the elements, if you can get them in a shaded area, get them some fluids, some water if they're still conscious, give them water, cool them down," Texoma Medical Center trauma program manager Emily Johnson says.
Johnson says if symptoms continue for an hour, seek medical treatment.
