Other viable answers (Added by users whilst learning):

- Sweating - increased heat loss through evaporation of water from skin - Hairs lie flat - removal of insulating layer - Vasodilation - blood vessels near skin surface dilate, resulting in more blood flow at surface of skin - more heat loss via radiation
