Abstract

A method of estimating a body temperature of an individual based on physiological data including a heart rate received from at least one sensor 510 and received environmental data. The physiological data and the environmental data are inputted into a model present on a processor 520. The model generates an estimated body temperature and an estimated physiological condition based on the inputs. The processor 520 compares the estimated physiological condition to a measured physiological condition in the physiological data. A controller 530 modifies at least one parameter in the model when the difference between the estimated physiological condition and the measured physiological condition is above a threshold.
