How do you prevent dizziness on a plane?

Can flying cause dizzy spells?

Flying does two things that are relevant to dizziness-- it may induce motion sickness, and it may stimulate the ear through pressure changes. There is a small literature about alternobaric vertigo. In small planes, dizziness may come from either or both mechanisms.

Can flying cause low blood pressure?

Airplane Travel and Blood Oxygen Saturation Typically, in-cabin air pressure is equivalent to that seen at 5000 to 8000 ft. Local hypoxia causes vasodilation (decrease in blood pressure) and increased capillary permeability, as well as increased ventilatory effort and heart rate.

Does flying affect your brain?

“At oxygen levels equivalent to altitudes above 12,000ft (3.6km), healthy adults can start to show measurable changes in their memory, their ability to perform calculations and make decisions,” BBC had reported earlier.
