Arthritic discomfort in flight
In response to the enquiry: “flying arthritis discomfort”
Arthritis and arthritic discomfort depend on humidity, barometric pressure, and the length of time one is exposed to high humidity and high barometric pressure.
Gout and painful swollen finger joints will grow quickly within ten days and become permanently swollen after being exposed to the cool, moist weather of San Francisco and the Bay Area down to Stanford, California, on the San Francisco Bay Area Peninsula.
The weather in San Jose and Milpitas is vastly different from that of San Francisco and the northern peninsula. Arthritis reacts differently to these two differing climates and weather conditions.
Severe arthritic pain occurs before the onset of heavy snowfall when one is in the Washington D.C. and northern Virginia area of Arlington and Falls Church. Right before the onset of heavy snowfall, the humidity and the barometric pressure are very high, and a person with arthritis will suffer very painfully.
Arthritic pain does not flare up when one is in Reno, Nevada, at around 6,000 ft. to 7,000 ft. in elevation above sea level where the air is thinner, the humidity is very low, the barometric pressure is lower, and the air is much drier.
Arthritis does not flare up in desert regions where it is dry and not humid, such as Death Valley in California and Las Vegas, Nevada.
Arthritis does not flare up when one is in the American Southwest including Arizona, New Mexico, and South Central including Texas down to the Gulf of Mexico.
Close observation by [Master Chen says] indicates that arthritic pain flareups occur when the humidity rises to above 47 with a barometric pressure of over 30 in.
The humidity and barometric pressure for several cities on April 4, 2014, are listed here for comparison:
The humidity in San Francisco, California, is 67% and the barometric pressure reads 30.04 in. This would be devastating to arthritic sufferers.
The typical cabin pressure of a passenger airliner is maintained at 8,000 ft. of flying altitude or 22.23 in. The humidity in the cabin of a passenger airliner is from 40% to 60%.
Arthritic discomfort would then be due to the higher humidity (humidity > 47%) in the cabin.
The humidity in Las Vegas, Nevada, is 17% and the barometric pressure reads 29.93 in. The throat will immediately lose moisture as soon as one leaves the hotel casino lobby and walks outside.
The humidity in Phoenix, Arizona, is 14% and the barometric pressure reads 29.91 in.
The humidity in Houston, Texas, is 36% and the barometric pressure reads 30.03 in. In Houston, slight arthritic pain will flare up occasionally when the humidity goes up to 47% or higher.
The humidity in Miami, Florida, is 52% and the barometric pressure reads 30.06 in.
The humidity in Arlington, Virginia, is 70% and the barometric pressure is 29.79 in.
The humidity in New York, New York, is 76% and the barometric pressure is 30 in.
Arthritic discomfort can flare up either from high humidity or from high barometric pressure independently or from both.
