The Eustachian tube is a narrow passage that connects your middle ear to the back of your throat. Its job is to equalize pressure and drain normal fluids. When you have a cold, the same nasal congestion and inflammation that stuffs up your nose can also swell and block this tiny tube. With the tube closed off, air gets trapped in the middle ear, pressure drops, and fluid can’t drain—creating that plugged, underwater feeling.
Fortunately, several methods can help alleviate the symptoms of a plugged ear. One of the most straightforward techniques is the Valsalva maneuver, which involves pinching the nostrils shut, closing the mouth, and gently blowing air through the nose to push air into the Eustachian tube and help equalize pressure in the ears. Another method is the Toynbee maneuver, where one pinches their nostrils shut and swallows to activate the muscles that open the Eustachian tube. Using a humidifier to add moisture to the air can help prevent nasal passages and the Eustachian tube from becoming congested. Nasal decongestants and saline nasal sprays can also provide relief by reducing swelling and clearing mucus. plugged ear with cold
