In the study, the researchers from the Universities of Cambridge and Tubingen write that for every degree of warming, there is a 0.87 per cent decrease in body mass.
For example, a 2C warming would be associated with a body size decrease of 1kg for someone weighing 60kg. The same trend works in reverse, so for every degree of cooling, body size increases by 0.87 per cent.
Being bigger means a person’s mass to surface area ratio is greater, and they are therefore more heat efficient and lose less warmth than smaller people.
