Answer 1

Your brain needs to drop in temp about 3-4°F to rapidly fall asleep.

So raising your temperature, then effectively shocking it with cold will cause exactly that. You will warm up properly shortly afterwards.
Plus you’re far more relaxed after a hot shower/bath which increases blood flow.
