It kind of depends on how much heat you are talking about. Here in Texas and most of the South we have lows temps around 80° and highs of 95°-100° with enough humidity to shrivel your soul.
I could tolerate working outdoors in the heat and playing softball after with no problems until I hit 60. Now the heat can kick my butt.
