Frozen feet

Feet after 3 minutes in Super Cold Treatment at -110 degrees celsius (-166 degrees Fahrenheit). It's a kind of large freezer cooled with liquid nitrogen were they put group of people for a short period of time.

Super cold treatment is supposed to have positive health effect. More on that here. Your body surface temperature drops to around +5 degrees celsius minimum in some parts (as legs), it dont actually freeze you. There is just white frost on leg hairs. :-)
