Triple Heater Meridian helps distribution of water and Ki 

If you have tinnitus, frequent colds, or shortness of breath; food retention issues like bloating and heartburn; water retention and reproductive organ problems; or are hypersensitive or overly vigilant, check out your Triple Heater Meridian. How can one meridian affect all these areas?

Known also as the Triple Energizer, this independent Yang energy system governs respiration, digestion, and elimination. Paired with the pericardium meridian and associated with not one but multiple organs, it incorporates multidimensional energy functions: the transformation, purification, and distribution of air, food, and water within three levels of the body. The upper heater is from the tongue base to the diaphragm; the middle encompasses the diaphragm to the navel; the lower is the navel to lower abdomen.

Sound important? It is! The triple heater is a transmitter and transport system for water and primordial Ki, which originates in the kidneys. The upper heater works with the heart and lungs to nourish cardiopulmonary functions; it controls the intake of air, food, and fluids, regulates respiration, and circulates protective Ki, which spreads nutrients and oxygen to the body. The middle heater nourishes respiratory and gastrointestinal/digestive functions of changing food into energy. The lower heater, while nourishing excretory and reproductive functions, prepares fluids for excretion and controls the Ki of fluid and nutrient absorption, waste disposal, and sexuality/reproduction.

From the ring fingers to the arms to the shoulders it travels, where one branch goes deep into the chest to the pericardium meridian, then to the abdomen. The other goes to the neck, ears, enters the face, and ends at the lateral corners of the eyes.

If you press the point located two inches below the navel in your dahnjon and it is uncomfortable or painful, there are energy problems. To revive the triple heater and relieve coldness and inflexibility, try Myungmoon breathing.

First, place both hands on your dahnjon and breathe and focus on the Myungmoon point (in the lower back opposite the navel). After sufficient breathing, strongly swipe your palms from your upper heater to your lower heater. Finally, swipe a circle three times over your dahnjon.
