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
In: Biology
Your body makes a lot of heat on its own. You get frostbite only when the air is so cold your body’s heat is not enough to prevent your limbs from freezing.
I don’t know if you meant 0C or 0F, but 0C/32F is not quite enough to cause frostbite in a hurry. If they were sitting still it’d be hours before they were in danger, but they’d probably be a lot less comfortable. They’re not sitting still: they’re playing a football game and doing a lot of rigorous physical activity. Their body is generating a lot of heat and they probably don’t even feel the cold.
0F would be more concerning, but I see charts indicating with a little wind that could still take up to 3 hours for frostbite risk. I have a feeling that’s for fingers and toes and other extremities, the arms are closer to the torso and “meatier” so they don’t tend to get frostbite so fast. There are also amenities like heaters on the sidelines.
Lots of physical exertion can stave off frostbite at those temperatures. That’s not an option for people in a survival scenario. But I guarantee you if one of these players complained they couldn’t feel their arms it’d take less than a minute to get them inside and surrounded by medical professionals.
