Hold up bro
You mean to say a person does better in the desert than opposed to -35 weather?
Had this 'discussion' before.
Have you ever been in -35 weather for any amount of time, even fully dressed in a parka? Any exposed skin gets frostbite within minutes, then you lose the finger or toe.
Let's take a mediate example. -30 vs +40. In +40 weather we're going to say the person can wear shorts and tshirt, same way the person on -30 can wear long pants, gloves and a jacket.The person in the heat can live for over four days, without water before dying of dehydration. But let's say the person can eat and drink normally in both extremes.
I was out doing my walks in -35 weather the other day. I had on two pairs of pants, two shirts, two pairs of socks, two fleeces (like hoodies), a winter jacket, two pairs of gloves and a toque. I actually started wearing a hat this year for the first time. So look at me all bundled up.
I had to come back into the house after 20 minutes (lots of snow) because my fingers, toes and nose started burning and tingling. A precursor to frostbite.
Now let's go one step further, I gotta take the bus, or walk somewhere in the same weather. No house to come back into. Another step...let's say I can't get anywhere indoors in the next 24 hours. Hypothermia will kill me.
Now imagine you're out during your hottest day. What is it in Virginia...90, 100 degrees F? If you had to walk let's say from the marina back to your house and it's 5 miles, you would make it. Now let's say we allow that you are dressed for the weather, meaning shorts and a tshirt. (same way I get all of those clothes above and winter jacket with gloves)
You're going to sweat and have an itchy asscrack, no doubt. But you can't seriously say or endorse the saying 'you can always warm up', when you've never spent even an hour in extreme cold. Your house barely reaches an indoor temp of over 70F in that weather because of how insulation works against extreme cold.
People who live here know this...you rarely are able to stay indoors for over a week in -35 weather. You have to go out and start cars, clear walks, get food, go to work....and that's assuming your vehicle always works and you're not away from it or an indoor place for over 10 minutes.
I've had the luxury of living in both sides of the thermometer. No joke when I said I've played football and worked in a warehouse in over 90F heat.
A person could never stand outside for three hours doing anything in -35.
