Pressure equalization

The child dives headfirst to a depth of about 1.5 meters. As soon as they feel pressure in their ears, they should hold their nose with one hand and try to blow gently through their nose to perform a pressure equalization in their ears. It’s best to demonstrate the pressure equalization to the child on land beforehand. It is important to note that water pressure increases with depth. At around 1.5 meters, the pressure can be felt as an uncomfortable sensation in the ears. When this pressure is noticed, a pressure equalization must be performed to prevent high pressure on the ears from causing serious injury.
