This study aims to predict temperature on human skin using mathematical equations and one-dimensional finite difference method bioheat transfer that is exposed to environmental conditions. The use of finite difference methods in the bioheat transfer equation is used to predict human skin temperature with the influence of temperature and environmental convection heat coefficient. In this case, human skin is divided into four parts: epidermis, dermis, fat, and muscle, which have different thermal conductivity. The results showed that the lower ambient temperature and the higher convection heat transfer coefficient resulted in a significant difference in temperature distribution between the surface temperature of the skin and the core of the body. The conclusion of this research shows that changes in environmental conditions by applying different methods to the equation of the bioheat transfer model affect the temperature distribution of human skin. Thus, causes changes in the body’s thermoregulation to maintain thermal stability.
