Ear - blocked at high altitudes
The air pressure outside of your body changes as altitude changes. This creates a difference in pressure on the two sides of the eardrum. You may feel pressure and blockage in the ears as a result.
High altitudes and blocked ears; Flying and blocked ears; Eustachian tube dysfunction - high altitude
The Eustachian tube is a connection between the middle ear and the back of the nose and upper throat.
Swallowing or yawning opens the eustachian tube and allows air to flow into or out of the middle ear. This helps equalize pressure on either side of the eardrum.
Doing these things can unclog blocked ears when you are going up or coming down from high altitudes. Chewing gum the entire time you are changing altitudes helps by causing you to swallow often. This may prevent your ears from getting blocked.
People who always have blocked ears when flying may want to take a decongestant about an hour before the flight leaves.
If your ears are blocked, you can try breathing in, then gently breathing out while holding your nostrils and mouth closed. Use care when doing this. If you breathe out too forcefully, you can cause ear infections by forcing bacteria into your ear canals. You can also create a hole (perforation) in your eardrum if you blow too hard.
