The paper describes the study of metabolic effect relying on dermal thicknesses of males and females for temperature distribution of the layers of dermal part at various atmospheric temperatures. The study has been carried out for one dimensional steady and unsteady cases using finite element method. Lower percentage of muscle mass and higher percentage of adipose tissue in subcutaneous part of females result lower metabolic rate compared to males. Metabolism is considered as a heat source within the body tissue. The appropriate physical and physiological parameters together with suitable boundary conditions that affect the heat regulations have been incorporated in the model.
