How can ear squeeze be prevented?

Preventing ear squeeze, which is a condition caused by pressure differences between the external environment and the air spaces in the ears, involves several effective techniques. One key method is the practice of equalizing pressure in the ears through maneuvers like jaw rotation, swallowing, or employing the Valsalva maneuver. These actions help to open the Eustachian tubes, allowing air to flow into the middle ear and equalize the pressure.

In addition to these techniques, relaxing is vital as it can help divers to remain calm, which contributes to equalization efforts. Being overly tense may hinder a diver's ability to effectively manage pressure changes.

Furthermore, it’s prudent to avoid diving when experiencing a cold, as congestion can obstruct the Eustachian tubes and complicate pressure equalization, increasing the risk of ear squeeze.

Collectively, these approaches encompass a comprehensive strategy for preventing ear squeeze, justifying the answer that considers all these methods together.
