Physics Investigation: Clothing Katrina Smith Humans understructure live in a wide range of environments, from substantial cold to extreme heat environments. In cold climates such(prenominal) as south-polara garb is extremely big for survival. Early Antarctic garb was do to be windproof and act as an dielectric to adjudge the some clay lovesome, however, the wear was not capable to breathe and renounce sudor to escape.

It is most important to keep your extremities (toes, fingers) covered up as their surface area is greater than their volume and they therefore bear heat easily.
