Counterintuitive, perhaps, but research shows it to be true.
To test the notion, Dr. J. Owen Hendley and other pediatric infectious disease researchers at the University of Virginia conducted CT scans and other measurements as subjects coughed, sneezed and blew their noses. In some cases, the subjects had an opaque dye dripped into their rear nasal cavities.
Coughing and sneezing generated little if any pressure in the nasal cavities. But nose blowing generated enormous pressure — “equivalent to a person’s diastolic blood pressure reading,” Dr. Hendley said — and propelled mucus into the sinuses every time. Dr. Hendley said it was unclear whether this was harmful, but added that during sickness it could shoot viruses or bacteria into the sinuses, and possibly cause further infection.

Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm characterized by rapid and irregular beating. Often it starts as brief periods of abnormal beating which ...心房顫動（英語：Atrial fibrillation，簡稱：AF 或 A-fib），又稱為心房微顫、房顫、心房細動（日本）、心房纖維性顫動、心房纖顫、房性纖顫等，是心臟不正常節律/心律不整的一種，特色是心臟快速而不規則的跳動^[2]
