The essence of plateau redness is a compensatory increase in red blood cells and haemoglobin as a result of long-term chronic cold temperatures and prolonged sun exposure leading to dermal capillary dilation and damage to the stratum corneum. Prolonged hypothermia and capillary dilation can be accompanied by hypoxia, resulting in an increase in red blood cells and haemoglobin making the peripheral circulation resistance increase and the heart load increase, which can easily lead to heart failure and pulmonary oedema. A cardiopulmonary examination can therefore help to identify suspected complications and manage risk factors.
