1. Take a cold shower.
Ah, there's nothing quite like a cold shower on a hot day, is there?
2. Go for a swim in a pool.
Bonus points if you swim angrily.
3. Go for a swim in a lake.
Bonus points if you don't let Leviathan loose into the world.
4. See a ghost ship, then go to a cemetery to kill the ghost and save your life.
This is actually a pretty risky move, so I wouldn't recommend it.
5. Summon Raphael, trap him in holy oil, then piss him off so he makes it rain inside your house.
This will probably get you killed, so it's clearly a method of last resort.
