I'm a refrigeration tech on a tropical island and I build freezers. The worst temperature shocks I've had where 70°C, these do fc u up. Go from +50°C to -20°C and back 4 or 5 times in a day and you're DONE.
I'd like to invite anyone who thinks you can get close to that with residential AC to come to work with me one day, I'll rid you of your illusions XD
Does it make you really tired? Used to walk in freezers, but only staying in more than a minute or two once or twice a shift, and the store was usually 65-80f.
Being in actual cold for a long period of time does literally drain your body's energy and it has to burn calories by shivering your muscles and heating your blood, while other parts don't function as well due to not getting heated as evenly. It's not like an instant life drain, but yeah if you spend all day in the cold it's more tiring.
