Or cold hands that come with other symptoms, such as joint pain, a new rash, weight loss, night sweats (as seen in connective tissue/autoimmune diseases), pallor, weakness, shortness of breath ...
For cold receptors their firing rate increases during cooling and decreases during warming. Some cold receptors also respond with a brief action potential discharge to high temperatures, i.e. typically above 45 °C, and this is known as a paradoxical response to heat [ citation needed ] .
Origins of heat and cold adaptations can be explained by climatic adaptation. [16] [17] Ambient air temperature affects how much energy investment the human body must make. The temperature that requires the least amount of energy investment is 21 °C (70 °F). [5] [disputed – discuss] The body controls its temperature through the hypothalamus.
Most often, frostbite occurs in the hands and feet. [7] [8] The initial symptoms are typically a feeling of cold and tingling or numbing. [1] This may be followed by clumsiness with a white or bluish color to the skin. [1] Swelling or blistering may occur following treatment. [1] Complications may include hypothermia or compartment syndrome. [2 ...
Any type of cold can be a trigger, including reaching into the freezer, holding a chilled drink or relaxing in an air conditioned room. Rare disorder can turn fingers and toes white or blue when ...
The condition can cause localized pain, discoloration (paleness), and sensations of cold and/or numbness. When exposed to cold temperatures, the blood supply to the fingers or toes, and in some cases the nose or earlobes, is markedly reduced; the skin turns pale or white (called pallor) and becomes cold and numb.
This prevents blood from losing heat to the surroundings and also prevents the core temperature dropping further. This process is called vasoconstriction. It is impossible to prevent all heat loss from the blood, only to reduce it. In extremely cold conditions, excessive vasoconstriction leads to numbness and pale skin.
