In this chapter, they discuss the practice of grounding, also known as earthing, and its effects on the body. They explain that when you make direct contact with the surface of the earth, you discharge into the earth and change the surface polarity in the body. They also debunk the myth that drinking alkaline water can change the pH of the blood and instead recommend drinking hydrogen water. They mention the benefits of hydrogen water, such as improved absorption of nutrients and supplements, and its effects on neural inflammatory disease and chronic inflammation.
