Fan off extreme heat

It's another scorcher out there Saturday.

A heat advisory is in effect in Orange and Seminole counties until 7 p.m. Saturday.  The temperatures will be hottest between 10 a.m. and 7 p.m.

Health officials are reminding people to take precautions to avoid heat exhaustion and heat stroke.
    
You don't need top notch weather equipment to know how hot it is today.

"You can really feel the heat.  You could almost like, grab it.  Like, touch it.  It's so hot out right now," said Jen Frye, personal trainer.

The heat is almost unavoidable at Lake Eola.

Most people come to walk their dogs or go for a run.

It's those people doing vigorous outdoor activities today that could become a victim.

"It is warm out there.  It is plenty humid.  It's a killer," said Matthew Bengston, runner.

The heat can get so bad, you could die.

But the effects come in stages beginning with heat exhaustion.

"One time I was working in the yard and I felt light headed.  I had to lay down for a little bit," said one resident.

Heat exhaustion can easily sneak up on you. 

Heat exhaustion symptoms:
Heavy sweating
Muscle Cramps
Weak or Tired
Dizziness
Headache
Nausea or Vomiting
Fainting
Seizure
Coma

Treatment:
Cool, non-alcoholic drinks

Air-Conditioning

"If you don't drink a lot of water, that's when you put yourself at risk," Frye said.

If you have to be out in the sun, cold fluids are the best treatment to avoid a close call.

"I guess I didn't drink enough and towards the end of the day I got kind of sick and like you'll get sick and throw up if you don't get enough water," Frye said.

If heat exhaustion is untreated, it can lead to heat stroke.

Heat stroke symptoms:
High Body Temperature
