Did you know when our bodies are exposed to cold over time, they actually start to change to keep themselves warm?
"We start to build up a tissue ... that we call brown adipose tissue — so brown fat," Dr Dino Premilovac from the University of Tasmania said.
"It's more muscle-like than it is fat-like in what it does.
"If we expose our bodies to the cold environment, the way our bodies deal with it over a long period of time is to produce more brown fat."
Brown fat's purpose in the body is to produce heat to warm up the blood, in turn keeping the body warm.
