Which ear point is used to prevent motion sickness and treat headaches and dizziness?

The ear point commonly used to prevent motion sickness and treat associated symptoms like headaches and dizziness is the Occiput point. This point is located on the ear and is specific to treating conditions related to the head and neck, making it particularly useful for relieving symptoms associated with motion sickness. The Occiput point is thought to have a calming effect on the central nervous system, which can help alleviate dizziness and promote a sense of balance.

In contrast, while Shen Men is known for its calming effects and is often used for stress and anxiety, it does not directly address motion sickness. The Eye point primarily targets visual-related issues, and the Stomach point focuses on digestive concerns. Therefore, for symptoms specifically related to motion sickness, the Occiput point is the most appropriate choice.
