9 Your ears pop. (Worse than you think.)
If you’ve ever flown anywhere, then you’ve already experienced the unpleasant popping sensation that happens when the plane takes off and lands. This painful popping, known as airplane ear, occurs when the air pressure in the environment is different from the air pressure in your middle ear. Air pressure rapidly changes as you ascend into the air or descend back onto land. Thankfully, chewing gum or yawning should effectively counteract the effects of the altitude change and return your ears back to normal.
