Idea: could this be an evolved trait? Could it be that sleeping less during hot weather was an evolutionary advantage? Maybe spending more time asleep during the winter, presumably when food/resources are scarce, lowered energy needs and so increased survivability. In hot climates, predators are more active at night. Maybe our aversion to sleeping during hot nights evolved from a need to stay awake when the lions/tigers/bears were out looking to eat us? That could be why I find it easier to sleep out in the sun in the middle of a summer day (siesta) than I do at the same temperature during the night.
