Other cold-related injuries that can be present either alone or in combination with hypothermia include: Chilblains: condition caused by repeated exposure of skin to temperatures just above freezing. The cold causes damage to small blood vessels in the skin. This damage is permanent and the redness and itching will return with additional exposure.
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 B 12 deficiency , fevers , fibromyalgia or vasoconstriction . [ 2 ]
Cold shocks cause the repression of several hundreds of genes in the bacterium E. coli. Many of these genes are repressed quickly after the decrease in temperature, while others are only affected several hours after this event. [11] The repression mechanism is described in. [12] Shortly, during cold-shocks, cellular energy levels decrease. This ...

This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
Allen's rule is a biological rule that says the limbs of endotherms are shorter in cold climates and longer in hot climates. Limb length affects the body's surface area, which helps with thermoregulation. Shorter limbs help to conserve heat, while longer limbs help to dissipate heat. [13]
