This post is a list of seasick remedies and preventions that have worked for me on my past cruises. I hope it helps!
Size of Ship/Roughness of Seas
The smaller the ship, the more movement you tend to feel. Of all the cruise ships I’ve been on, the worst experience of seasickness I’ve had was on a smaller ship. We also had windy conditions during this cruise, so I didn’t feel miserable until the weather worsened, thankfully it was on the last couple of days of the trip. Many of the bigger ships are more stable and you will feel less of the rocking back and forth.
On an Alaskan day cruise, I was on a ~200 passenger ship and I felt every wave. Once we cruised into a bay, and the waves were smaller, the sickness subsided by a large degree, but being on such a small boat leads to some discomfort.
Wear Sea-Bands
While on one cruise, I needed some seasickness relief and found these Sea-Band Wristbands. These appealed to me since they were non-medicinal and non-drowsy. I thought they might have been a gimmick, but I was wrong. They are great! I wear them on planes, boats, and long car trips. 
I’ve also met a few people who wear them and have more serious seasickness than I do and they are never without these bands. Check them out!
Fresh Air
One of the best remedies is to get fresh air, preferably with some wind on you. This is one reason I enjoy having a balcony on cruises, I can step into a breeze anytime, have privacy, and be in the shade. Interior rooms can make you feel closed in/panicked and I think increase your awareness of the ships movement. From my understanding, this is because the inner ear knows your body is moving, but what you are looking at is motionless, the signals are then confused and this leads to motion sickness. So if you are prone to seasickness consider a balcony or window cabin, or be prepared to spend a lot of time outside on decks (which you should totally do anyways!). At the very least, look out the window at the horizon so that you see the motion your inner ear senses.
Take a Nap
I have found that taking a quick nap really helps to feel better. On long car rides, when I start to feel sick, I’ll take a nap (while I’m not driving of course!). I also take naps on cruises. While on the day cruise in Alaska, I was miserable, but after a nap, I felt refreshed and enjoyed the rest of the cruise. A nap will help your body reset itself. Besides, it’s a vacation, you are supposed to relax!
Middle of Ship/Cabin Location
Spend some time in the middle of the ship, where the back and forth motion of the boat will be less extreme. Booking a room near the center of the ship can ease discomfort at night. Avoid rooms that are near public spaces, as the noises and bright lights might be disturbing. A stateroom on a lower deck will also reduce the amount of motion. Balconies provide easy access to fresh air if that helps the most.
A few more Tips:
- Carry a ‘Just in Case’ Bag. This can help ease your panic over being sick.
- Choose cruises with more port days and less days sailing.
- Stay hydrated with water.
- Stay busy with ship activities to keep your mind off of sickness.
- Consider medicine for severe seasickness.
- Don’t be afraid to eat!
Until next time,
