Why Do Your Ears Pop on an Airplane?

If you have ever flown in an airplane, you may have felt a strange pressure in your ears during takeoff or landing. Then suddenly: pop.

It can feel weird, annoying, or even a little uncomfortable. But your ears are not broken. They are reacting to air pressure.

Air Has Pressure

Air may seem light, but it still pushes on things. The air around you is always pressing on your body from every direction. At sea level, there is a lot of air above you, so the air pressure is higher. Higher up in the sky, there is less air above you, so the pressure is lower.

When an airplane takes off, it climbs into air with lower pressure. When it lands, it returns to air with higher pressure. Even though airplane cabins are pressurized to keep passengers safe and comfortable, the pressure inside the cabin still changes. Your ears notice.

Your Eardrum Feels the Difference

Inside your ear is a thin piece of tissue called the eardrum. It vibrates when sound hits it, helping you hear. There is air on both sides of your eardrum: air outside your ear, and air behind the eardrum in your middle ear.

For your ear to feel normal, the pressure on both sides of the eardrum needs to be balanced. When the pressure outside your ear changes quickly, the pressure behind your eardrum may not change right away. That pressure difference can push or pull on your eardrum. That is the full, clogged, or uncomfortable feeling you get.

The Eustachian Tube Helps Fix It

Your body has a small tube called the Eustachian tube. It connects your middle ear to the back of your throat. Most of the time, this tube is closed. But when you swallow, yawn, or chew, it can open for a moment.

When it opens, air can move in or out of your middle ear. That helps balance the pressure on both sides of your eardrum. The pop you feel is the pressure suddenly evening out.

Why Landing Can Feel Worse Than Takeoff

Many people notice their ears more during landing than during takeoff. That is because during landing, the air pressure in the cabin increases as the plane gets closer to the ground. Your middle ear needs to let more air in to match the outside pressure.

If your Eustachian tubes do not open easily, your eardrums can feel squeezed inward. That can hurt more than the pressure change during takeoff. This is also why flying with a cold can be uncomfortable: if your nose and throat are stuffy, the Eustachian tubes may not open as easily.

Why Swallowing or Yawning Helps

Swallowing and yawning move muscles near the Eustachian tubes. That movement can help the tubes open. Chewing gum, sipping water, or yawning during takeoff and landing can help your ears adjust because those actions encourage the pressure-balancing system to work.

Babies often cry on airplanes partly because they feel ear pressure but do not know how to fix it. Crying makes them move their throat and mouth, which can actually help their ears pop.

The Big Idea

Your ears pop on airplanes because air pressure changes as the plane climbs or lands. Your eardrum feels the difference, and your Eustachian tubes help balance the pressure.
