Evaluation of the effects of cold and hot environmental temperatures on the spatial distribution of facial skin temperature

Abstract

In the Covid-19 disaster, fever detection using infrared thermography became widespread. A person with fever is detected based on the facial skin temperature measured in a non-invasive and free-of-restraint method. Recent studies have pointed out that the facial whole skin temperature, when measured immediately after entering a moderately moderate environment from a cold environment, is not practical for detecting persons with fever because it is greatly affected by the environmental temperature. On the other hand, the effect of cold and hot temperatures on the details of the entire face has not been evaluated. In this study, we compared the cold and hot environments and the acclimation to moderate temperatures to The effects of cold and hot environments on the whole face skin temperature distribution was evaluated in detail.The results showed that the periorbital area and side of the nose were least affected in the cold environment, and the side of the the nose was least affected in the hot environment. And, These parts are suggested to be suitable for core temperature estimation considering the environmental temperature.
