The Southeast Alabama Medical Center Emergency staff has had to see three patients because of heat-related illnesses Wednesday.
That's compared to the many they've already cared for because of the extreme temperatures.
With the heat index soaring many people are having a hard time protecting themselves from injury.
Heat stroke primarily affects older people, while heat-exhaustion can affect just about everyone.
Experts advise people to stay hydrated because heat exhaustion could easily progress to a deadly heat stroke.
Doctors also say if you or someone you know has any symptoms of a heat injury to call emergency personnel immediately.
