Cooling my forehead by applying water has helped me fall asleep, especially on warm days. I suspect an inability to fall asleep plus chaotic mind wandering is often related to an overheated brain and that this is a good artificial way to help the body cool your head. Brain cooling is supposedly one of the purposes behind yawning, but at least for me, yawning can't seem to keep up Note: if you try this, don't dry the forehead after applying water. The main longterm cooling mechanism is through slow evaporation just like with sweat
