Cold soothes me. I'm always hot, but cold is very grounding to me. I live in Western Europe, in a "temperate oceanic" climate which is kind of fortunate, although I still think it's too hot.

When I want to calm down before bed I go outside in a t-shirt even if it's January (and/or raining), and if I'm panicking or very confused I have the tendency to strip. Not too bad - I always stay decent, but everything that can go goes.
