I am an expert on sea sickness.
Been getting seasick all my life. The first time, I was 3 years old on a ship coming back from Panama with the family. I still have vivid memories of the puke flowing back and forth on the deck in our state room as the ship rolled in the rough seas. I’ve been sick on every boat I’ve ever owned, except my kayaks. I think that’s why I like the kayaks so much. Maybe it’s because the kayak is closer to being in the water or maybe because I just can’t (or don’t) go in rough enough seas to get sick.
The sickest I’ve ever been was on a submarine. I worked in the shipyard and had to ride sea trials. We had just completed a test called “emergency blow”. While the sub is cruising at a depth of 1000 feet, all the ballast tank valves are opened at once, releasing air into the outer hull of the sub. The purpose of this maneuver is to surface the sub as fast as possible in an emergency. Riding the sub up during emergency blow is quite fun. You have to hang on to something and you really rock and roll when it hits the surface. But the fun stops when you get to the surface. Now the sub has used all the air in the ballast tanks, so diving again with them empty would be very unsafe. Safety protocols call for all air banks in the ballast tanks to be full before the sub is allowed to dive again. The air banks are recharged by several large air compressors that must draw air from a snorkel on the sail of the sub. (The “sail” is the structure that sticks up above the top deck of the sub. On older subs, it was called the conning tower.) The air bank recharging process takes 12 hours! Upon surfacing at completion of one particular emergency blow, we were met with 20-foot seas with a 15 second period 200 miles east of Cape Hatteras. The modern nuclear submarine is not designed to run on the surface, having a round hull like a big pipe. They roll side-to-side, as well as pitching up and down with the swells. While riding on the surface in such a sea state, the bow goes up 20 feet, then down 20 every 30 seconds, while rolling side to side to a 20-degree angle. Lots of yaw along with all that pitch all at the same time! I wedged myself prone on the deck in the Forward Sonar Equipment Space hugging a mop bucket for 12 hours.

From these many queasy years of experience on the ocean, I have learned what to do to avoid getting sick: dose up, stay topside in the fresh air, look at the horizon, eat light, etc. And, if all else fails, lay down to shut off the balancing mechanism in the inner ear. I also made a promise to myself to never ride another submarine on sea trails (five was enough!).
Seasick dive students.
When I became a scuba instructor, I found myself dealing with a lot of seasick students. No matter how much I warn them in class, they don’t believe they will get sick and don’t take precautions. “I’ve never been seasick in by life”, how many times have I heard that! They’ve just never been on a bouncy little dive boat at anchor in four-foot seas. Everybody has their amplitude and frequency of ocean swells that will make them sick. You can go out on boats and ships for years and just not hit your waveform. Seems those small bouncy dive boats hit a lot of people’s waveform.
It’s easy to tell when someone is starting to get sick. They get quiet, sit with their head down, eyes closed or looking at the deck, and turning white. Next will come the first purge, if preventive action is not taken. I try to tell them I understand how they feel from personal experience and, if they do what I say, it will help a lot. “Stand up, walk around and take some deep breaths of fresh air (stay out of the engines’ diesel fumes!).” “Look at the horizon!” And lastly, “Go to the back of the boat, if you are going to throw up!” But they don’t listen. They are incapable of listening. I’ve come to believe; this is a subdued version of the “flight or fight” reaction. The sea sickness won’t let them do what’s best to help them! The sickness is telling them to do all the stuff that will make it worse!
The disease tells you to do the wrong things.
The next series of events include holding a bucket under their face or physically moving them to the stern during uncontrolled projectile vomiting. I signal to the dive master to start cleaning the puke off everyone’s dive gear and the decks and quit making stupid jokes! I try to get the victim to drink some water and go for a swim off the back of the boat. This is also hard to get them to do, even though it really helps. Then they don’t want to go on the dive, even though that will really help. So much lost money, training time, and quitters caused by this terrible disease.
All this is preventable as I’ve proved to myself over many years. But it is hard to correct once the disease is in control. I got to wondering, might what I’ve learned about seasickness apply to other sicknesses?
Do other diseases do the same thing? fatigue? depression? alcoholism?
Depression does the same thing to us. I know depression and it’s not fun. It makes you want to hide away from people, lay around, watch TV, eat, and drink. The negative self-talk that runs through the brain seems unstoppable. Yet any first-year medical student can tell you what to do: exercise, read, get some good sleep, and just go get busy with something. Hard to do, though, when you just don’t feel like doin’ nothing!
Same with drinking. The only real cure for a hangover is more drinking!
Fatigue from work stress, family stress, or old age is common. Fatigue is self consuming like seasickness and depression and just tells you to do nothing which leads to more fatigue. Be aware of the fatigue and don’t listen to it. But start slow with a short walk or anything that gets you out of bed or off the couch. Don’t push it, but do something, anything but laying there and letting it consume you.
I don’t know why we are wired this way.
But I have learned how to fix it. Get in charge of the brain. You are the boss, not that bad puppy of a brain. Your brain pumps shit! And the worse you feel, the more shit the brain pumps. Learn that and you’re halfway there. Stop listening to the random crap spewing from that shit pump. Call yourself to attention and start giving some orders that make since and make you healthier and happier!
