Relief Bands are the only devices we know of that can stop seasickness once it’s started. Many passengers have purchased their own after renting ours. Developed by NASA for airsick astronauts, the Relief Band works on the same principle as the sea bands which go on your wrists and exert gentle pressure. The difference is Relief Bands emit an electronic pulse, which is far more effective. You wear one like a watch, but with the face on the inner aspect of the wrist. It’s FDA approved for use with pregnant women and chemotherapy patients. It’s approved for over-the-counter use to prevent travel sickness. We have rented Relief Bands for over six years now and we remain very impressed, but there are limitations. Nothing works for everyone. We rent the devices for $7. They run out fast, so we recommend purchasing your rental in advance along with your tickets.
