Shaking head is one of the most common methods people use to get rid of water in their ears, but it can also cause complications as researchers have found that trapped water in the ear canals can cause infection and brain damage.

Researchers at Cornell University and Virginia Tech in the US, revealed that 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 Indian-origin researcher and study author Anuj Baskota from Cornell University.
