How long does it take to get frostbite?

How long does it take to get frostbite? Inspired by the polar vortex, childhood myths and a bitterly cold Michigan winter, we set out to find out more about frostbite, and just how dangerous going out in cold weather is.

Stood outside in crocs with no socks at 38f with windchill, I felt the effects of frost bite starting to set in at the hour mark. Took 20 minutes to slowly warm my toes and they’re still hurting.

[@johnb6723]

I think you are telling fibs. Lol. It's impossible to get frostbite at 38f. Period.

[@Mariiiam]

How are you doing now? Was it anything significant?

[@TrkyClub]

@@johnb6723 it was 38 when I left my house at 6pm, it dropped below freezing within the hour I was out without socks

[@TrkyClub]

@@Mariiiam No lasting damage. Burned like fire to warm them and they were real sore for about 24 hours, otherwise I’m fine. Still have all my piggies. And they cute too

[@drewbennett1253]

Great summary on a genuinely local topic of late, to think "vortex" would become part of ones daily lexicon is enough to make me bundle up. Great job Risk Bites Team!

[@freshgreent8]

Michigan on the map !

What if your wearing shorts bare legged in extreme cold and waiting 2 to 5mins for a bus and the breeze is very light it would take 30mins or more to get frostbite and plus I take cold showers to get my skin used to the cold.

[@draconianking]

I never want to live anywhere where I might get frostbite.
But with all this climate change I might have to move continents.

[@FranzKrammer4746]

Global warming is good news for you then ..but just on average...our winter has been unusally cold and wet (i.e ice and snow)

[@sandesh__aryal]

@@FranzKrammer4746 are you guys still active?

[@snewberg]

[@FranzKrammer4746]

Weather reports in Canada include a wind chill factor to give an equivalent risk temperature.

[@riskbites]

They do in the US as well. The difficulty is that wind chill is a subjective index of how cold it feels, and so can be misleading in ters of the "freezing power" of the weather.

[@FranzKrammer4746]

of course.... now you've guessed my specialty... engineers have really resisted the measuring of the subjective factor...Example: I used to ride motorcycle throughout the winter...it's a challenge

[@riskbites]

Franz K Excessive wind freeze I would imagine!

[@FranzKrammer4746]

Risk Bites the wind just magnifies the effect of the existing temperature...the existing temperature causes the frostbite..even without wind ... I rode a motorcycle through the Canadian winter

[@dakotaoreilly7961]

"In grown up numbers"
Ha, I love that

[@buckabuckler4413]

Meanwhile in russia: skinny dipping into a frozen lake or rolling in snow naked is considered good for the heart ❤

[@checkout5017]

If you're in derry on a cold winter morning on your way to school it wouldn't be long!

[@jaceworld7360]

So if it's lower than 32 degrees does that mean you can get frostbite

[@relaxedcloud]

Thats Cameron Boyce not Jace norman

[@bobuxman1759]

I live in a place where it is almost imposible to get frost bite, in the 8/9 years Ive lived here we have had snow mabey once or twice

[@kozmicflush980]

... and where is that?
don't write the comment if your not gonna tell us what this snowless place is, that you speak of...

[@koushikdas1992]

​@@kozmicflush980England probably.

Had to stop watching since every thing is in Fahrenheit.

[@kingsg5195]

Quick tip you should edit out tht breath you take before talking its very annyoing sry much love

[@jeremyduvitt6584]

0 degrees in grown up numbers 🙌🏻
