Phrynops turtles generally achieve thermoregulation through areal basking. In order to best attain its goal, it tends to increase its basking time during mid-day during the winters to make up for the cold. Other factors such as food intake and reproduction underwater also influence the way it controls the temperature of its body. Although this is the main way it is able to maintain body temperature, food intake and reproduction rates are also influential in the matter.[citation needed]
