Seasickness, sorted in 90 seconds.
You shouldn't have to white-knuckle a cruise. Dizzout's sound therapy works through any headphones to settle the inner-ear mismatch that makes ships feel like a bad idea. Drug-free. No drowsy patches. No bracelets.
Why ships make your stomach revolt
Boats and ships don't move like cars. The motion is rolling, pitching, and slow - sometimes all at once. Your inner ear feels every degree of sway. Your eyes, locked on a stable-looking cabin wall or ceiling, see almost nothing happening. Your brain decides the disagreement is suspicious and pulls the nausea lever.
Big modern cruise ships hide the motion well most of the time - hydraulic stabilizers reduce roll significantly. But in rough seas, no ship is fully immune, and on smaller vessels every passenger feels every swell. About one in four cruise passengers still experiences seasickness even on the biggest ships.
For the full mechanism, the science page has the deep dive.
Why sound therapy works on a ship
Calibrated low-frequency audio delivered through your headphones stimulates the same inner-ear organs that are sending the “we're moving” signal your eyes are contradicting. With a clean, consistent input from the ears, the mismatch shrinks and the nausea response calms down. Most users feel a shift within about 90 seconds.
No drugs means no drowsiness, no dry mouth, no blurry vision. You can use it before boarding, when symptoms hit, or anywhere in between.

Stop motion sickness in 90 seconds - no pills needed.
Drug-free relief. Works in cars, planes, boats, and VR. Any headphones.
Sailing a specific ship?
Each major cruise ship has its own motion profile. The newest Icon-class ships from Royal Caribbean barely feel the sea; older mid-size vessels move more. Browse a few:

Common questions
Is seasickness really worse on small boats than big ships?+
Yes. Modern cruise ships have hydraulic stabilizers that cut roll motion by 80-90%. A fishing charter or sailboat in the same swell will be vastly more uncomfortable. Ship size, hull design, and stabilizer technology all matter.
Will Dizzout work if I'm already throwing up?+
It might still help, but you've waited too long for ideal results. The earlier you start a session - at the first sign of cold sweat or yawning - the better the response. Once vomiting has started, get to a low midship spot, fresh air, and keep trying.
Do I need the patch for a 7-day cruise?+
Many people get through 7-day cruises with sound therapy and ginger alone. Sea conditions matter more than length - a calm Caribbean week is easier than a 3-day Atlantic crossing. We have a per-ship motion guide at /motion-sickness/cruise that covers what to expect on different itineraries.
What about the inner-ear vertigo I sometimes get after a cruise?+
That's mal de débarquement syndrome - the persistent rocking sensation after a long voyage. It's distinct from seasickness and usually fades on its own. Sound therapy may help while it resolves but isn't a cure. See a doctor if it lasts more than a few weeks.
Best cabin for seasickness?+
Midship, low deck. That's the pivot point of the ship - the spot that moves least. Avoid the bow, stern, and high decks. We list recommended cabin areas for each major ship at /motion-sickness/cruise.
