Cold sensitivity or cold intolerance is unusual discomfort felt by some people when in a cool environment.[1]
Cold sensitivity may be a symptom of hypothyroidism, anemia, low body weight, iron deficiency, vitamin B12 deficiency, fevers, fibromyalgia or vasoconstriction.[2] There may also be differences in people in the expression of uncoupling proteins, thus affecting their amount of thermogenesis. Psychology may also play a factor in perceived temperature.[3]
