In a human, the hypothalamic set point for core temperature is unknown. When the core temperature (T_core) exceeds the set point, sweating begins at a rate (L/min) = 0.1 × (T_core - set_point). Each litre of sweat evaporated removes 0.6 °C from the core. A subject initially has T_core = 38 °C. After 5 minutes of exposure, the core temperature falls to 37 °C. Assuming the sweating rate remains constant during this interval, determine the hypothalamic set point (in °C) to one decimal place.
