Water doesn't always get into your ears, and when it does, it's usually due to a lack of protective measures. Here's a breakdown of how your ears naturally resist water entry, and how you can enhance that protection:
-
Natural Barriers:
- Earwax (Cerumen): Earwax is hydrophobic, meaning it repels water. While a small amount of water might touch the eardrum, the earwax helps to prevent large quantities from entering.
- Ear Canal Shape: The S-shape of the ear canal provides some degree of natural protection against water directly entering.
-
When Water Does Get In: Water typically gets into your ears when swimming, bathing, or showering. The small amount of water that enters usually drains out on its own.
-
How to Prevent Water from Entering:
- Earplugs: The most effective method is using earplugs specifically designed for swimming or water activities. They create a physical barrier preventing water from entering the ear canal.
- Swim Caps: While not as effective as earplugs, swim caps can help to reduce the amount of water that comes into contact with your ears.
- Proper Swimming Technique: Keeping your head above water as much as possible reduces the chance of water entering your ears.
- Head Position: Tilting your head to the side after being submerged can help water drain naturally.
-
What to do if Water Gets Trapped:
- Tilt Head and Jiggle Ear: Tilt your head to the side with the affected ear facing down and gently jiggle your earlobe.
- Valsalva Maneuver (Use with caution): Gently try to pop your ears by pinching your nose, closing your mouth, and gently blowing. Be careful not to blow too hard.
In essence, while your ear has natural defenses, using earplugs and swim caps provides the best protection against water entering your ear canal during water activities.
