The Valsalva maneuver is a simple yet effective breathing technique in which one exhales against a closed mouth and nose. This maneuver helps regulate pressure within the ear, which can provide immediate relief from discomfort caused by blocked ears due to changes in altitude, sinus congestion, or ear infections, said Dr Nayan K Shetty, consultant ENT surgeon, Wockhardt Hospital Mumbai Central. "It involves taking a deep breath, closing your mouth and nose, and gently blowing towards the back of your throat until your ears pop," said Dr Deepti Sinha, lead consultant, Dept of ENT at the CK Birla Hospital®, Delhi. So, does it also prove useful during air travel? According to Dr Shetty, by equalising pressure between the middle ear and the environment, it can help alleviate ear pain and restore normal hearing sensations. "Valsalva maneuver is used for mild ear barotrauma, a common issue during air travel or underwater diving. It is a safe, non-invasive method to clear the Eustachian tubes, reducing pressure and relieving the sensation of fullness in the ears," said Dr Shetty. However, while this technique is generally harmless, it should be performed cautiously to avoid potential strain or injury. While this technique is generally safe, it should be avoided in certain situations, said Dr Sinha. "If you have an ongoing cough or cold, performing the Valsalva maneuver can push infection into the ear, increasing the risk of complications like ear infections. Additionally, individuals with glaucoma, retinopathy, or congenital heart disease should avoid this maneuver, as it can put undue pressure on the eyes, heart, or blood vessels," said Dr Sinha. Dr Sinha added that if you have a cold and your flight is already scheduled, it’s best to consult an ENT specialist for safer alternatives to managing ear and sinus pressure.
