How To Yawn #10
Gas pressure works locally as well as systemically.
Take the case of heartburn — Vomiting Lite.
What happens when we vomit?
Gas pressure causes retroperistalsis (the reverse of peristalsis), traveling all the way from the middle of the small intestine into the toilet (hopefully, not on the carpet).
D.J. Bowrey, M.K. Roy, P.D. Carey, & G.W.B. Clark (“Is the lower esophageal sphincter pressure the same at night as during the day time? The same on different days?,” The Esophagogastric Junction, May 1998) wrote …
“In summary, stationary manometry provides the most useful method for determining LES characteristics including sphincter pressure. As a consequence of the test being performed under standard conditions in the supine position there is little variation in sphincter pressure in health, range 6-25 mmHg. The controlled conditions facilitate the reproducibility of sphincter pressure measurements in different centers specializing in esophageal function testing. It would appear that LES pressure varies throughout the ‘circadian cycle’ on an intra-individual basis, and on an interindividual basis. It is higher in the supine position when compared with the erect posture; it is higher in the fasting state compared with the post-prandial state; and is increased by factors that result in an increased intra-abdominal pressure. LES pressure is lowered as a consequence of exercise.”
The LES is the lower esophageal sphincter, also called the cardiac sphincter.
What’s the takeaway from the above?
Standing up can reduce heartburn. Lying down can increase it.
Exercise can reduce heartburn. Fasting can increase it.
The UES is the upper esophageal sphincter, also called the inferior pharyngeal sphincter.
It keeps you from swallowing air.
That’s why chewing gum relieves heartburn (as long as its not peppermint or spearmint gum).
Chewing gum increases the swallowing of both saliva and air.
Swallowing opens the UES, moving air down into the stomach.
This reverses the pressure gradient, opposing the acid reflux, moving the stomach contents in the opposite direction.
Exercising while chewing gum keeps it moving in the right direction.
Remember, sucking and swallowing are camouflaged yawning.
For those who can’t get past the pH paradigm, Nineteenth Century physicians had no doubts about whether a specific case of heartburn was “caused” by either acidity or alkalinity.
Instead of theorizing, they tested with baking soda.
If a patient bloated, they either had enough or too much acid.
If they didn’t bloat, they either had none or too little.
Heartburn has much in common with the formation pore pressure gradient encountered while drilling for oil.
Heartburn is a “well kick.”
Vomiting is a “well blowout.” A “wild well.” A “gusher.”
Uncontrolled blowouts are rare today because of blowout preventer valves (BOP valves).
Is there a BOP valve in the human body?
Not one, more than several, and they weaken with “aging” and strengthen with exercise and down-aging.
The Core and Lumbo-Pelvic-Hip Complex prevent “well kick,” including the diaphragm muscle, transverse abdominus, internal and external obliques, internal and external intercostals, quadratus lumborum, and pelvic floor muscles (puborectalis, pubococcygeus, iliococcygeus, coccygeus, deep transverse perineal, sphincter urethrae, external anal sphincter, bulbospongiosus, ischiocavernosus, and superficial transverse perineal muscles).
The more you know about these “core” muscles and the more you exercise them, the healthier and less prone to heartburn you will be.
What about those of you who choose to be healthier and less prone to heartburn, but don’t want to become anatomy adepts?
Pandiculate (yawn and stretch), do Breath of Fire pranayama and belly dancing, and do lots of hip thrusting during sex, and you can avoid memorizing the muscles of the Core and Lumbo-Pelvic-Hip Complex.
