Abstract: An electronic device may include: a first temperature sensor configured to measure a first temperature of body skin; a second temperature sensor configured to measure a second temperature at a position spaced apart from the body skin; and a processor configured to estimate skin heat loss based on the first temperature and the second temperature, and to determine a target ambient temperature for controlling an ambient temperature based on the first temperature and the skin heat loss.
