Is cold actually good for you? We've all heard stories about long-lived people from Northern Europe and the hardiness of those who live in cold environments, but can these benefits be available to everyone? Can you avoid sickness and infirmity by exposing yourself to the cold? What are the actual mechanisms of how cold adaptation affects the human body? We'll explore these questions and more on today's Health and Wellness show - The Benefits of Cold Adaptation. Included as always will be Zoya's Pet Health Segment. Join us weekly on Fridays on the SOTT Radio Network!

Due to the time change, today's show will begin at 11 am EST (4 pm CET).

There's still an hour to go, I think. And the chat appears only half an hour before the show.

Yes, I just came back to say that the countdown started over for another hour. Or, maybe I was reading it wrong. :rolleyes:

Yes we're starting at 11 EST today because of the US time change and the lack of time change in Europe, so that Gaby can participate, and European listeners get the same time as usual. :) Sigh, time changes...
 
Time zone changes at the end of March here in Europe. Nearly there :)
 
Feeling Chilly? It’s in Your Genes.

This holiday season I received no less than five sweaters, one space heater, a fleece lined sweatshirt, and one wonderful electric blanket. Why? It’s very well known that I’m constantly freezing. My teeth have even been known to chatter at the balmy 60 F, the same threshold at which my mother allowed my brothers to wear shorts while we waited for the school bus as kids.

A study published recently revealed something I’m clearly missing: a cold-tolerant gene. This gene variant, possessed by the Inuit, Native Americans, and some Siberians, is thought to cause “a certain type of body fat known as ‘brown fat’ to generate heat,” in addition to being involved in other traits like body fat distribution, bone, and facial structure.

This gene variant is very similar to a gene sequence found in the Denisovans (“extinct humans who once ranged from Siberia to the Southeast”). An earlier discovery had proposed that the Tibetans had also inherited a variant from the Denisovans, which allowed them “to use oxygen efficiently when the air is thin at high altitudes.”

Prior to this study, it had been recognized that one of the clusters of genes involved in cold tolerance was “significantly associated with different phenotypes including fatty acid profiles, weight, and height.” That had been notable, when considering cold-tolerance, because “short, stocky stature was an evolutionary adaption for cold weather since it consolidated heat.” Unfortunately, I don’t seem to be consolidating heat that way.

Another factor working against me is that women seem to feel cold more often than men (this comic by Blue Chair notwithstanding). Many people have observed anecdotal evidence for this, but researchers also found that women tended to possess higher core temperatures, but have consistently colder hands and feet—possibly leaving them feeling colder.

All in all, it looks as though I’m going to continue shivering, but at least now I have some answers.
