3. Find the Horizon
It might not be the ears that are confused however but rather the eyes. This is what can happen when we get seasick or car sick. Here, the ears detect movement but when we look at our friends and fellow travelers, they appear to be static in relation to us – as does any furniture.
Hence: vertigo. Focus on the horizon outside the vehicle then and this can help. Likewise, it can help when no vehicle was ever involved!
