  −
*Slow chilling can cause vasoconstriction, cellular damage -> secondary vasodilation and increased permeability -> oedema
  −
*Severe and persistent cold causes vasoconstriction, increase in blood viscosity and tissue anoxia
  −
*Lesions may occur in wet or hypoglycaemic neonates or animals recently moved from warm to cold environment
  −
