Quote:While the heat and humidity can certainly affect some players, I don't think that it's as big of an advantage that most people think.  I'll never forget Donvan McNabb blowing chunks a few years back, but for the most part it really won't affect 98% of NFL players.

 

The main negative effects humidity has on players are cramps and dehydration, which cause players to temporarily be removed from the game. Breathing problems usually happen in mile-high Denver, where oxygen masks are available on both sidelines. I am sure there is a slight advantage or we would not wear white jerseys and pants in September, even though it is not much.
