While floating in water and Epson salt, the body reaches a state of deep relaxation that otherwise would only be reached while sleeping. The deep relaxation also allows the brain to reduce its electrical activity. The brain goes into a wave pattern known as Theta State.
In the Theta State the body releases endorphins – The “Feel-Good” hormones. While the body is releasing Endorphins, the harmful chemicals that increase stress, Cortisol “the Stress Hormone”, Adrenaline, ACTH and Lactate, are removed from the blood stream. Floating opens the door for the body to get rid of harmful chemicals allowing Endorphins to take over.
Research has shown that High levels of cortical, and ACTH debilitate the Immune system. The production of Endorphins lowers the levels of Cortical and ACTH given the Immune System a boost.
