In Scandinavian countries, there is a traditional saying that suggests wearing fewer layers before winter to prepare for the cold and more layers before summer to prepare for heat.

“there's a saying that I think essentially translates to in the fall when when you're approaching winter you want to actually wear fewer layers not bundle up when you go outside so that you can prepare yourself for the cold of winter and be able to heat yourself up using your brown fat and that in the spring as the temperatures are warming rather than removing layers you want to wear more layers in order to be a little bit uncomfortably warm so that In the Heat of the summer you're better at Cooling your body”
