Watching the Dolphins/Chiefs game and some of those players had bare arms… how do they not get frostbite or lose feeling in limbs?
ETA: 0°F

Working keeps you warm; you’re told from a very young age in the subarctic that stopping in -40° for even just a minute will kill you, not *might* kill you—stopping **will** kill you. And that’s life 🤷🏽♀️
0° is nothing really, frostbite happens when your moisture is totally sucked dry from under your skin and it takes a minute. But water closes the pores immediately and essentially “turns off” the patch of skin that was affected,
but sweat… that ensures you have a constant supply of moisture under the skin and your skin won’t “turn off” at all.
Football players are constantly in motion and have elevated body temperatures from working to begin with, plus with all that sweat it’s like they are being heated from the inside.
