Visiting high altitudes increases the likelihood of ear infections
the verdict
SUPPORTED
the evidence backs this
confidence 81/100
Evidence indicates that visiting high altitudes creates barometric pressure differentials and hypoxic conditions that impair Eustachian tube function and middle ear pressure regulation, increasing the risk of ear-related complications.
