It's not that the body is resistant, it's that the body acclimates to the change. Sort of like if you move from the country into the city, you'll be awake when you hear sirens. Then after time passes, your brain grows to accept the noise as "normal", and those sirens stop waking you up.

Look up cold habituation or sensory adaptation. I think it either that the cells that have thermoreceptors become harder to activate due to changes in thermoreceptor expression, or the connection between these peripheral cells and the cells in your brain that interpret the signals a "ow, cold" becomes less efficient. Or both!
