Cold sensitivity or cold intolerance is unusual discomfort felt by some people when in a cool environment.
Cold sensitivity may be a symptom of hypothyroidism, anemia, low body weight, iron deficiency, vitamin B12 deficiency, fevers, fibromyalgia or vasoconstriction. 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.
Possible causes include Non-freezing cold injury.
