Water is not only vital internally, it also has powerful external uses. Used strategically, external water treatments (hydrotherapy) can improve circulation and help a host of diseases. Be sure to take note of some of Dr DeRose's favorite hydrotherapy strategies.

Day 13's Challenge: Use hydrotherapy (water applied externally) at least weekly to address a specific health issue.
