There is no more effective way to bring down your body temperature than with cold water. Submerging your body in ice water works the fastest, but cold showers also help. This combination can be deadly due to heatstroke, which occurs when a person’s internal body temperature reaches 103 degrees or higher. Granted, you may not have access to ice during a blackout, but regular cold tap water should still help significantly. Each summer night, I laugh at myself marveling at the absurd, imperfect link between my mind, my body, and the weather.
