Cold sensitivity

 ( Sensitivities ) 

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, Fever, 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.
