People who aren’t accustomed to heat aren’t going to know the signs, or what to do. It goes the other way around as well. I grew up in Florida, and I’m a very fair redhead. I’ve been avoiding radiation poisoning my whole life. I learned how to swim in an extra large men’s white undershirt. I worked a pool bar, carrying 30lbs worth of drinks in sand when it was 100 degrees outside. People had heatstroke sitting down while I was dancing around them. I was used to it, I had 6 layers of sunscreen on me and I drank a 24 oz glass of water every half hour or so.

That being said, I moved to Massachusetts a few years ago. Our boiler had a minor issue, and our heat was out. My husband and I just put on more clothes until the tech could come out. We happened to be dog sitting for our neighbor that day. When he brought her over, we told him about it the boiler and brought a sweater for the dog. He then asked us if we needed some firewood. We then realized it hadn’t dawned on us to light the fireplace. We’ve never had one before. It wasn’t instinct for us to do that. We had wood. We’re just idiots when it comes to cold.
