Getting or not getting “seasick” is a subject I have been meaning to write about for quite awhile now. I had partially addressed it in the excerpt below which I published two years ago. But I never made the follow-up post of my reflections on the subject and conclusions after the three month and 5,000-mile passage from North Africa to the Panama Canal. A video I made on our nice Christmas Day

That’s 5,000 miles in strong, 18 to 36 knot winds produced by the northeasterly trade winds. While these winds are called the NE Trades, because that is their long-term direction, the actually winds on this passage were NE through SE, with three distinct swells from those directions with differing amplitudes and periods.  This produced 8 to 16-foot seas with relatively short periods of 6 to 8 seconds from the NE thru the SE. Not the most pleasant conditions, even for a boat like Dauntless that loves following seas. In fact, this was the most difficult conditions with following seas we’ve ever encountered.

Some of the worst conditions possible if one is prone to seasickness, with the boat corkscrewing its way across the Atlantic at 7 knots. I expected that as I got my sea legs, sea sickness would be just a bad memory.  But no, in fact, it was to the contrary. It got me to wondering what was really going on.

Stress builds and crossing an ocean is stressful in the best of conditions. For one, my insurance does not cover me past 200 miles off-shore. So, abandoning ship is not an option. For another, with a three-week passage, you are asking every component to work 24/7 for that time period and if something does go wrong, how to minimize the damage.  Therefore, it’s a constant weighing of risks, rewards.  E.g. Can I fix this problem with the engine running or do I increase the chances of something else going wrong by turning off the engine?

This is what I had written two years ago, just days after leaving Morocco for the Canaries at the very start of my second Atlantic Passage:

Morocco to the Canaries

Four days on the North Atlantic, 600 nm, four days, 1 hour, 35 minutes, what could go wrong?

For one, we found the weak link on this Krogen, it’s me.

In my first year of cruising, I would get sea sick maybe a quarter of the time. Now in my third year, it’s more like three-quarters of the time.

What’s changed? Who knows?  I’m older, but usually one’s body becomes more adapted. No, I think the problem is in my brain. 

When conditions are rough, I know to take a remedy or put on the Scopolamine transdermal patch. I’ve been using the patch for more than 3 years, now all of a sudden, the patch gives me a bad rash, but it’s also very effective as long as I put it on the night before departure.

With nice cruising conditions, or I should say, relatively nice, with winds and seas less than 15 knots and 3 feet (1m), respectively, I never had to worry, now, if the slightest unexpected event happens, I get seasick.

This last episode was one of the worst I’ve ever had.  But I’m not 100% sure it’s “seasickness”.  It’s more like my body gets a whole load of adrenaline and then when crisis is over, my body doesn’t know what to do. 

…

We were heading 240 degrees, with Southeast winds 20 to 25 knots, producing seas from the south of 4 to 8 feet. 

The paravanes work most effectively with seas on the beam, so our ride was actually not so bad with a gentle rolling of 8 degrees to the lee side and 4 degrees to the windward side.  

On the 3rd day out of Morocco, I was in the galley filling my water bottle, when I felt the boat motion change. I looked out the salon window to see the windward paravane bird being dragged on top of the water, clearly broken. 

I purposely take my time and want to remain calm. I finish filling my water bottle. I go to stop the boat, neutral, idle, then up to the fly bridge to retrieve the pole and the broken bird. 

Dauntless is quite tame when not underway, in other words, she rolls much less.  So, there was no big crisis.

The two spare birds are stored in the lazerette.  The one that broke had been repaired in Ireland, as it had previously broken crossing the North Sea. So, I wasn’t too worried as to the cause.  We had two spares in the lazzerette. The one on the starboard side was easier to reach, but as we tried to get it out, the fin of the bird became lodged under the generator exhaust hose. And the more stuck it became; the more stressed I became.  I didn’t like the idea of leaving it as it, with its metal fin pressed against the exhaust hose and the wooden bird, so close to the hydraulic rudder piston. But after 10 minutes of trying dislodge it, I gave up, unloaded the port side of the lazzerette and got the other bird that was stored on the other side of the lazerette.

It took just another minute to replace the broken one and we were underway again, finally 20 minutes later, having spent most of that time, trying to get the one bird out. 

Underway again, all was OK, but I was feeling very strange. Very strange.

I went to change my clothes, as I was very hot, sweaty and covered in anti-corrosion oil I had sprayed liberally in the lazzerette before leaving.

But after changing my clothes, I felt worse; like overheating badly, I figured a shower would help.

I shower, figuring that cooling off would make me feel better, but now, I can’t even dry myself off. It was a bizarre feeling. I wasn’t able to stand up or move. I dragged myself to bed and lay on top.

I figure I just need a little rest, but had wanted to walk around the boat, make sure all is OK before we get underway again. So, after a few minutes, getting more stressed because I knew Micah and Dauntless were waiting for me, as I go to put on my shirt, I became violently ill. First time that’s happened in years, even though, I get sea sick a lot and have that miserable nauseous feeling, I don’t throw up. This time I did.

I finally understood that I can do nothing but lay on top of my bed naked. I couldn’t even dry myself off. I use what little strength I have to tell Micah to make sure everything looks OK and to get underway.

I stayed on top of the bed and went to sleep.

Three hours later, I am up and OK. Like it never happened.

After I posted the above, my friend Dan added this comment:

“I have read of at least one person who has spent decades at sea who get sea sick every time they set to sea for three days or so. They, like so many, take a while to get their sea legs, and then they are just fine. What was interesting about this person is that they ONLY get sea sick when they are captain. If they are crewing on a boat, they don’t get sea sick at all. Their guess was that the stress of being captain was what caused the sea sickness.”

By the time we arrived in the Caribbean, I’d had two more stressful incidents and very similar physical reactions. Not only that, but suddenly, my skin was very allergic to the adhesive on this particular batch of Trans-dermal patches. So, I couldn’t wear it anymore and I’m left with these two quarter sized areas behind by ears of no pigmentation. No Michael Jackson jokes please.

I had also started to see a pattern. On Christmas Day, it was one of the calmest of the trip, with seas not more than 8 feet and winds in the mid to high teens. We saw whales that day and had a couple cruise with us for about 15 minutes. They were 30 to 40 feet in length and swam underwater next to the paravane bird. 

Christmas being more important to my nephew Micah than myself, I wanted to make a special dinner, so I BBQed the last of four delicious Canary Island Tee Bone Steaks. The best ever.

As soon as I had served our dinner, I had that feeling of “seasickness” come over me. A bit of nausea and overall weakness.

Sitting in Martinique in the wonderful marina Le Marin, I had time to reflect on what was really going on. In all my cases of “seasickness”, the motion of the boat was actually less than it had been over any given period of time. Also, it was clear that I wasn’t sick before a crisis, I wasn’t sick during the crisis, but as soon as the crisis was over, I was sick.

Didn’t really sound like motion sickness to me, but more a reaction to stress.

I’s already stopped using the Transdermal patch and now I decided to not take any more seasickness medicine at all, when we left Martinique for the Panama Canal

I also decided to take a shower every morning before my watch and every night before bed. The shower in the morning seemed to calm me down. I had no idea why, but starting my day at a lower anxiety level seemed to make a significant difference.

From Martinique to San Francisco, a distance of 3,600 miles and 90+ days of cruising, in some of the worst seas I have ever encountered, I’ve taken an anti-nausea medicine only twice.

I now understand that that terrible “seasick” felling was my body adjusting to the lack of adrenaline that the stress had produced and my para-sympathetic system was now getting my body back to normal.

Clearly the shower in the morning or before my watch, makes a significant difference.

And then in the November 30, 2018 Wall Street Journal, they did a book review of the book, Never-Home-Alone

And the shower in the morning starts to make sense scientific sense.

Here is the article from the Journal (bolding and underline is mine):

‘Never Home Alone’ Review: The Critters Chez Nous

In trying to rid our homes of insects, fungi and the like, we’re forcing the species around us to evolve ever faster—often at our own expense.

Lisa Margonelli reviews “Never Home Alone” by Rob Dunn.

When Rob Dunn was a young ecologist he rummaged through rainforests in search of biodiversity. More recently he discovered another type of wilderness: In a study of 1,000 houses in the U.S., Mr. Dunn’s team found 80,000 kinds of bacteria and archaea hidden inside—that’s at least 10 times the number of bird and mammal species observed in all of the Americas.

He soon also unearthed in our homes some 40,000 kinds of fungi and hundreds of insects, many yet to be named by entomologists.

“I was ecstatic,” Mr. Dunn writes. “Back in the jungle again, albeit the jungle of everyday life.”

In his fascinating new book, “Never Home Alone: From Microbes to Millipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live,” Mr. Dunn brings a scientist’s sensibility to our domestic jungle by exploring the paradox of the modern home: In trying to make it “clean,” we’re forcing the species around us to evolve ever faster—often at our own expense.

Mr. Dunn is a fine writer, wringing poetry out of the microbial explorations of Antonie van Leeuwenhoek, who spent half the 17th century documenting all the tiny living things around him—in his neighbor’s mouth, in the snow, in cheese rinds and in wasps. Leeuwenhoek “was to become an astronaut of the miniature,” Mr. Dunn tells us, “all alone exploring a realm that was more diverse and elaborate than anyone but him seemed to understand.”

Mr. Dunn also gracefully explains, without getting bogged down in details, the technology that has allowed scientists during the past decade or so to sequence the DNA of millions of previously unknown microbes, making his book an excellent layperson’s guide to cutting-edge research.

Mr. Dunn’s larger purpose is to explain how the ecology of the home has gone awry. Once upon a time, we lived in leaf huts, with interiors that looked a lot like our outdoor environment.

Soon we moved to round houses, then square houses and finally to air-tight apartments in cities.

Now we close our windows, use products that claim to kill 99% of germs and have unknowingly domesticated bedbugs—so they adjust their workdays around ours.

Our homes no longer resemble the garden outside but have a weird human-centered microbial signature that is also found on the International Space Station, and that’s not a good thing.

The problem, according to Mr. Dunn, “is not what is present but instead what is absent. The problem has to do with what happens when we create homes devoid of nearly all biodiversity except that which falls from us and then, for twenty-three hours of the day, we don’t go outside.”

To understand how mundane and occasionally deadly this evolutionary project of ours is, consider the shower head. In many American homes, water is treated with chlorine and chloramine, which kill pathogens but not mycobacteria, a genus that includes the cause of tuberculosis.

Meanwhile, in homes with water drawn from wells, nonharmful microbes flourish, including mycobacteria’s natural competitors.

By wiping out all the other bacteria in chlorinated water, we create environments where troublesome microbes thrive and even evolve.

This has led Mr. Dunn, together with his colleague Noah Fierer, to find that mycobacteria in shower heads can accurately predict instances of mycobacterial infections, as well as the regions where these outbreaks are likely to occur. 

And yet mycobacteria are not entirely bad. One species has been found to enhance serotonin production, which can lead to greater happiness and lower stress. Mice exposed to a species of mycobacteria are more likely to remain calm when facing a bigger, more aggressive mouse. 

Might this also explain how a morning shower helps us deal with a stressful commute and a bad day on the job? 

These twin stories—of scientific discovery right under our noses and the perilous impact of our unwitting genetic engineering—thread through Mr. Dunn’s book.

Cockroaches were once easily lured with glucose baits but have now rapidly evolved to dislike sweet things. Good strategy for the cockroaches, more troubling for us.

“Just as military specialists study the battles of the past to prepare for the future,” Mr. Dunn suggests that “we might consider our battle with the German cockroach in contemplating our own evolutionary future.”

“Never Home Alone” is a prescription for more biodiversity in the home and, more specifically, a plea for more attention to ecology. The more we understand how different creatures interact and influence our immune systems, the healthier we may be. But in the service of getting more people into ecology, Mr. Dunn believes the field needs to deliver tangible products.

He wants to systematically explore the species in our homes to determine which ones could contain useful chemistry. The camel cricket, a previously unnoticed and rarely studied thumb-size little bugger that lives—possibly by the billions—in American basements, has gut bacteria that can break down black liquor, a highly alkaline toxic waste produced by the paper industry.

The thief ant traipsing across your kitchen counter also produces an antibiotic that may eventually be useful against hard-to-fight infections. Personally, what I want to see is a home “makeunder “show dedicated to “rewilding” homes—similar to what you’d see on the Learning Channel, only more anarchic.

A bunch of giggling scientists show up at the door, toss the hand sanitizer, the shower head, the Sheetrock and the fungus-laden air conditioner.

In their place, they hand the homeowner a bar of soap, throw open the windows, install a ball of spiders to fight flies in the basement and start a batch of sourdough—all in the service of re-creating the garden indoors.

No doubt there will be tension in the idea of a wild domicile. Even King Tut, Mr. Dunn notes, was buried with a fly swatter.

Ms. Margonelli is the author, most recently, of “Underbug: An Obsessive Tale of Termites and Technology.” ■
