WODs in excessive heat / humidity

I am in Mexico and traveling south towards the equator. Have my gym in the van and I guess the WOD today is irrelevant but the big questions I have are these:

1. How hot is too hot? According to the weather channel, the temp today was 100 and it "feels like" 109.

2. Are there specific warning signs I should be aware of... I mean more than the typical every single workout feeling of shortness of breath, pukey, etc. that happens pretty much every time. I mean if I push too hard, wil I just suddenly pass out with no warning?

3. Is there a "safe" time limit before heat stroke is a problem?

I was of course staying hydrated and I normally live in Arizona so the heat is not the big issue, I think it is the humidity because my body pours sweat and looses the capacity to cool itself whereas in AZ the sweat evaporates and it does not feel so miserable.

I want to push hard but also stay safe. Thanks!

Re: WODs in excessive heat / humidity


I currently train at CrossFit Revolver in Cancún and have no problem with the heat.

Some days we even run 400/800mts under the sun (mid day) and are ok.

Now, the box has AC so as soon as u walk in its cool.

What I've felt/found:
- a certain tolerance has build up.
- keep hydration!!!!
- yes it more tiring that with overcast days.

I'd watch out for sun poisoning, or over exposure... As said, hydration and "cooling down" properly...

Wear proper/comfortable clothing that makes sweat repellent or cooling to prevent irritations and rubbing from humidity.

Watch for sunstroke signals and build up to it. You should be ok like us

Now, I do finish more tired on sunny days than overcast..

Coconut water seems to help a lot and good luck trainig under the sun!

Come say hi if in Cancun!

Re: WODs in excessive heat / humidity

Your body gets used to it over time, but you have to always stay hydrated, as expected.

I have always been someone who easily got heat stroke from being in the sun all day, but I've never once had a problem with a hour long workout in 90F+ weather.

I personally love working out in a hot/humid environment. Gets the sweat pouring and you warm up a lot easier.

Re: WODs in excessive heat / humidity

I workout in Texas on the Gulf coast in a gym with no a/c. Our conditions are identical to what you describe. The heat indices due to the humidity are usually in the 109-115 range. My times are muuuuuuuuch slower (although they doesn't feel slower) in the summer, but I just struggle through them knowing that it makes you mentally tougher. The most important things are to stay hydrated and make sure you are getting plenty of minerals/electrolytes like salt and potassium. The best salt to use is sea salt or other natural salt that has a variety of minerals.
