>>1510272The cold is no fucking joke. You have to have really good gear to stay warm or frostbite will take your legs then gangrene will set in and kill you. You also need to protect your skin from wind and dehydration. Drink lots of liquids and eat well. Oils and beeswax salves are used to protect skin, as well as coverings obviously. In places where there's lots of snow, "snow blindness" is a thing, so snow goggles are needed to prevent that. Which are made from bone like in this image.
Check out the gear the inuits use in the worst of worst conditions,

>how, in term of effects, -10 differs from -20, -30 to -40, etc.It is just an increase in insulation need, heat loss speed, and rewarming times.
