Shaking head to clear wet from ears is bad

Recommended Posts

"Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers at Cornell University and Virginia Tech show shaking the head to free trapped water can cause brain damage in small children."

 

"“Our research mainly focuses on the acceleration required to get the water out of the ear canal,” said Baskota. “The critical acceleration that we obtained experimentally on glass tubes and 3D printed ear canals was around the range of 10 times the force of gravity for infant ear sizes, which could cause damage to the brain.”

"For adults, the acceleration was lower due to the larger diameter of the ear canals. They said the overall volume and position of the water in the canal changes the acceleration needed to remove it."
