When the heat index reaches 103, heat cramps or heat exhaustion are likely. 

A heat stroke is even possible for those who are forced to be in the heat for hours at a time. 
Channel 3 spoke to a doctor about how to stay safe this week. 

Unless you're able to stay inside all week,  there's really no way you can avoid this heat.

Doctor Derek Worley at Erlanger North, says the more the temperature rises,  the more patients his office sees.  But Doctor Worley says the majority of those patients are young athletes,  who are kicking off sports around this time of year. 

He says most of their complaints while in the heat,  consist of dehydration, nausea, headaches, dizziness, and fatigue.  But as the symptoms grow more severe,  it becomes a neurological issue.

Doctor Worley says he hasn't had to treat anyone at the hospital so far,  and he wants to keep it that way. He says everyone can help by doing one thing

Dr. Derek Worley, Erlanger North, "Even if you're not thirsty if you're going to be out in the heat you need to force yourself to be aware that you need to be drinking because when you feel the thirst you're actually already behind and maybe becoming dehydrated."

If you're an athlete, work outside, or are exposed to the heat for an extended amount of time,  Doctor Worley encourages everyone to take breaks, get some shade if you can, and again stay hydrated.
