Summer is here and many people have been getting summer bod ready.

Intense heat can cause our bodies to shut down.

"As the internal temperature increases beyond 105, then the function of the body actually decreases and finally ceases," said to Dr. Dan Quan an attending physician, medical toxicologist from the Maricopa Medical Center.

In Phoenix, it can be tough to jog outside when it's more than 100 degrees, but it's not impossible. Your best protection -- doctors say -- is to do everything you can to keep your body cool.


"The outside temperature can go up to 140 but as long as you are able to cool yourself down by sweating or drinking fluids," said Quan.

If you decide to work out in scorching heat, make sure you acclimate your body first. It takes about a 10 to 14 days to really get your body used working out in extensive heat, according to Dr. Quan.

Not only should you slowly acclimate your body to working out in the heat, but you should also be cautious about the gear you wear.

"Working out without wearing a shirt or something covering your skin, can actually make you feel hotter because direct sunlight can increase the amount of heat you feel by 15 degrees," said Quan.

If you aren't careful, heat stroke can strike and put your life is at risk.

"All organs pretty much shut down at that point. Kidneys are impaired. Liver is impaired. The ability to breathe is impaired as well because everything is controlled by the brain," Quan said.

The first signs to look out for: If you stop sweating, feel nauseous, and are extremely fatigued.

That's when it's time to seek medical attention.

"If you get the warning signs from heat illness and you don't heed them. Things can really go downhill quickly," said Quan.

What about people who do obstacles courses, marathons and even Spartan tournaments with very little clothing?

Recently, 12 News spoke to host Dhani Jones (former NFL Linebacker) and course reporter Evan Dollard about a new show called Spartan: Ultimate Team Challenge on NBC.

"120, 130 or sub-zero temperatures, or whether we are in water or whether we are in winter time, spring, it doesn't matter. You know that's the thing about Spartan," Jones said when we asked if it would be impossible to do an obstacle course it in Phoenix when it could above 120 degrees.

Yikes. It must take a lot of mind control to be able to do such a rigorous obstacle course in such extreme temperatures.

The new show will raise the bar on team competitions, as groups will push through the pain for a chance to win $250,000.

The obstacle course includes a lot of mud, barbed wire, rope-burning climbs, and as the team progresses, the course worsens.

Now, imagine doing that in 120 degree weather.
