Ahh, damn. I didn’t catch that

The part about losing most of our body heat through our heads is a myth. If your head is the only thing not covered then yes, you will lose more heat through your head, so you’re not wrong in that regard.

It may also be poor circulation, I have bad verifies veins and my feet are always cold, even in the summer time.

That or she may have Raynaud's disease. Lots of people do. I have it and my body can be actually very hot but because of vasospasm my feet are ice cold. They go numb in wintertime.

Losing most of your body heat through your head isn't true. You're correct that if your head is the only part of your body that isn't "insulated" ie under a blanket, then yes you will lose more there. But in general, you lose a lot of heat through your hands and feet because your fingers and toes act to greatly increase surface area for heat transfer to your surroundings

Thanks for the suggestion. I remember that heat loss through the head being debunked a few years ago. She probably does have poor circulation though 😬
