A research group led by Takumi Kagawa and Masashi Kato at Nagoya University Graduate School of Medicine has discovered that stimulating the inner ear with a 100hz sound reduces motion sickness afterwards. They tested it on mice and men. If you are sailing and prone to sea sickness, you may want to replicate their findings by listening to the sound for at least one minute. Here is a 100hz sine wave mp3 I made myself for you to download.
Read “A unique sound alleviates motion sickness” to learn more about this effect. I would appreciate a comment on your experience. Takumi Kagawa and Masashi Kato maybe too.

The study, “Just 1-min exposure to a pure tone at 100 Hz with daily exposable sound pressure levels may improve motion sickness,” was published in Environmental Health and Preventive Medicine on March 25, 2025, at DOI: 10.1265/ehpm.24-00247.
