Leopard geckos behaviourally regulate toward a fairly narrow preferred body temperature when given a full thermal gradient
Thermal preference research on the species shows they actively select a specific temperature range by moving between warmer and cooler zones, which is the underlying reason a proper thermal gradient, not just an average enclosure temperature, matters so much in captivity.

Most active at dawn and dusk when temperatures in their native Pakistan and Afghanistan are ideal.
