Valsalva maneuver can help protect ears during air travel: Doctor
Valsalva maneuver is a technique involving taking a deep breath, closing the mouth and nose, and gently blowing towards the back of the throat until the ears pop. Doing this can provide immediate relief from discomfort caused by blocked ears during air travel or underwater-diving, Dr Nayan Shetty said. However, it shouldn't be performed during an ongoing cough or cold.
