How do you Equalise your ears?
Try forcing a yawn several times until the ears pop open. Swallowing helps to activate the muscles that open the eustachian tube. Sipping water or sucking on hard candy can help to increase the need to swallow. If yawning and swallowing do not work, take a deep breath and pinch the nose shut.

Is holding your nose and blowing bad for your ears?
Pop Your Ears by Holding Your Nose
Lightly blow out against the pressure. This should make your ears pop. The pressure you’re blowing against forces your Eustachian tubes open a little which drains pressure and fluid stuck in your ear. It’s a common misconception that this method is dangerous.
What happens if you don’t equalize when diving?
However, if a diver does not equalize early or often enough, the pressure differential can force the soft tissues together, closing the ends of the tubes. Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results.
Can you pop your ears underwater?
It can happen in the water, too. Scuba divers call it “ear squeeze.” As a diver goes deeper underwater, the pressure in the middle ear (the part behind the eardrum) is “squeezed” by the increasing pressure of the water from outside.
How do you unclog a eustachian tube?
Blocked eustachian tubes often get better on their own. You may be able to open the blocked tubes with a simple exercise. Close your mouth, hold your nose, and gently blow as if you are blowing your nose. Yawning and chewing gum also may help.
At what depth do you need to equalize?
A diver needs to equalize approximately every two to three feet (1 m). Doing so is particularly important in the first 15 to 30 feet (5 to 10 m) of the dive. This is when the largest proportional pressure change takes place. The art of equalizing ear and sinus cavities is to do it early and often.
How often do you have to equalize when diving?
Most authorities recommend equalizing every two feet of descent. At a fairly slow descent rate of 60 feet per minute, that’s an equalization every two seconds. Many divers descend much faster and should be equalizing constantly.
What part of the mask makes you see the underwater clearer?
Press the top ridge of your mask firmly to your forehead while slowly opening the bottom seal and blowing hard through your nose. Tilt your head back slightly, looking up while exhaling through your nose. This step should help the air you blow out to push the water out of the mask.
Why does the light of a flashlight look less bright underwater?
The deeper you dive the darker it gets. Water absorbs sunlight, and greater depth equals less light.
