Temperature of the extremities is a significant factor in temperature control of the body due to the presence of thermal receptors in the extremities. The brain uses signals from these thermal receptors as an indication of environmental conditions, and responds accordingly. Thermal monitoring of extremities and adjustment of extremity temperature are valuable in controlling body temperature, leading to a more optimum body temperature in an array of environmental conditions. Devices, such as a wearable article, and an apparatus to monitor the temperature of extremities, adjust the temperature of the extremities in response to the monitored temperature.
