Do acupressure wristbands work for motion sickness?
Verdict: Mixed
The evidence genuinely conflicts, and the larger trial designed to test exactly this found nothing: neither acupressure bands nor placebo prevented motion sickness, whether worn correctly or incorrectly.
What it's claimed to do
Sea-Bands and their many imitators press a plastic stud against the P6 (Neiguan) point on the inner wrist. They are cheap, sold in every pharmacy and airport, and enormously popular.
- YesTested for motion sickness and it held up.
- ProbablyReal trial support, but modest or from a single study.
- Mixedthis remedyTrials disagree — some found an effect, better-designed ones did not.
- UntestedNo one has tested this for motion sickness. It may still be sensible.
- NoTested for motion sickness and it did not beat a placebo.
Levels describe the state of the published research on motion sickness specifically — not on nausea in general, and not how well something worked for any individual. “Untested” means no trial has looked; it is not the same as a remedy having been tested and failed.
What the research actually says
Two laboratory studies, opposite answers. Hu and colleagues found in 1995 that P6 acupressure reduced nausea during drum rotation compared with sham acupressure, dummy-point acupressure and no treatment — a well-structured comparison that makes it hard to dismiss as pure placebo. Then Miller and Muth built a study specifically around the commercial products and the question of whether people wear them properly. Seventy-seven people were assigned to an Acuband or a ReliefBand, either trained in correct placement or not, or to a placebo, and exposed to optokinetic drum rotation. Their conclusion was blunt: neither band nor placebo prevented the development of motion sickness, regardless of whether the bands were used correctly or incorrectly. It is worth knowing what does not exist here. A Cochrane systematic review of acupressure for motion sickness was registered but withdrawn in 2015 without ever being completed, so there is no gold-standard synthesis to appeal to — despite how often one is implied. Anyone telling you the evidence is settled, in either direction, is overstating it.

Acuband and ReliefBand, worn by trained and untrained subjects, versus placebo, under optokinetic drum rotation. Authors' conclusion: neither band nor placebo prevented the development of motion sickness, regardless of whether the bands were used correctly or incorrectly.

Participants: 64 adults across four conditions
P6 acupressure produced significantly less nausea during drum rotation than sham acupressure, dummy-point acupressure and control (p < 0.0001), along with less abnormal gastric activity. Dummy-point acupressure did not produce the benefit.
Read the source →Safety & what to watch for
- Both trials were laboratory studies using rotating drums, not real journeys. Neither tells you directly what happens on a ferry.
- A placebo effect is still an effect you can feel — it is simply not evidence the mechanism works. If a band helps you, that is a real experience, and the bands are harmless.
- Worn too tight or for a long trip, the stud can leave a pressure mark or make your hand tingle. Loosen it if that happens.
- The main cost of a band that does not work is not the money — it is choosing it instead of something with better evidence on a journey that matters.
If you want to try it
- If you want to try one, put it on before you travel: the P6 point is about three finger-widths up from the wrist crease, between the two tendons, and both wrists are usually recommended.
- Do not make it your only plan for a crossing you cannot afford to lose. Pair it with a forward view and slow breathing, which have better evidence and cost nothing.
- They are a reasonable option for children and in pregnancy precisely because they are harmless — but discuss pregnancy nausea with a midwife or doctor rather than relying on a band.
- If you have tried a band twice on similar journeys and felt no difference, that is your answer; the trial evidence would not predict otherwise.
Something with better evidence: Does controlled breathing help motion sickness — verdict probably, and it costs nothing to try.

Frequently asked questions
Do Sea-Bands actually work, or is it placebo?+
The honest answer is that we do not know, and the best-designed trial of the commercial bands found no benefit over placebo. An earlier study of P6 acupressure did find a real effect against sham. Both can be true if the technique matters more than the product.
Is there a Cochrane review of acupressure for motion sickness?+
No. One was registered as a protocol and withdrawn in 2015 without being completed. This matters because the absence is frequently glossed over, and a withdrawn protocol is sometimes cited as though it were a finished review.
Why do acupressure bands seem to work better for other kinds of nausea?+
P6 stimulation has a stronger evidence base in post-operative and chemotherapy-related nausea than in motion sickness. One suggestion is that it acts more effectively on nausea of chemical or surgical origin than on nausea generated by sensory conflict — but that is a hypothesis, not an established fact.
Where exactly is the P6 point?+
On the inner forearm, about three finger-widths below the wrist crease, in the hollow between the two central tendons. That is the spot the bands are designed to press and the one you can press yourself for free.
