Disclosed herein is an apparatus and a method for controlling heat according to a use environment of a wireless communication terminal in the wireless communication terminal. The method includes measuring an internal temperature of the wireless communication terminal when the wireless communication terminal performs communication by using a predetermined channel or band. The method includes acquiring a heat control method matched to a currently-measured internal temperature from a heat control table having temperature ranges of heat generated within the wireless communication terminal, after the wireless communication terminal selects at least one of bands or channels and performs communication by using the selected at least one band or channel, and storing a heat control method in each temperature range. The method includes controlling the heat generated within the wireless communication terminal according to the acquired heat control method.
