Does a hot soak work better than a hot shower because sitting in a tub drains blood out of your head, but a hot shower - especially if spraying hot water on your head - doesn't?
Also causes me to wonder if keeping ice cubes in the mouth, pressed against roof of mouth, while sitting your lower half down into a hot tub could be an enhanced, if not all that more eccentric, strategy?
Maybe if in a cold climate, sitting in hot tub, while sticking head out the window into the freezing air. Could at least provide an opportunity to converse with neighbors while aborting an attack.
