Sea sickness.....
They say the only real cure for sea sickness (Mal de mer) is to sit under an apple tree… on land… that doesn’t move!
Most people who spend time at sea will suffer from sea sickness at some point. Some actually suffer the reverse of ‘land sickness’ too! We all have a story about that one time when…! Humans have fought against sea sickness for all time. Ancient Greeks called it the ‘plague of the sea’ and famous sufferers include Admiral Horatio Nelson and Christopher Columbus. Charles Darwin once wrote ‘The misery I endured from sea sickness is far, far beyond what I ever guessed’ and ‘if it were not for sea sickness, the whole world would be sailors.
Symptoms include: nausea, vomiting, dehydration, headache, dizziness, muscle spasms, drowsiness, lethargy, excess saliva, sweating and burping.
So what causes this debilitating, incapacitating infliction for which there is no cure?
In simple terms, it’s what happens when your inner ear balance system reacts to the unfamiliar motion of being on water. It’s the same reaction that causes car, or any other kind of motion sickness. The movement of the vessel you’re on causes the fluid in your inner ear to slosh around and this stresses the part of your brain that handles balance. The signals the brain receives are telling it that the things you see, such as walls and furniture should be still. But, on a boat, everything is moving constantly, including you. The air, the sea and everything on the boat is moving. This confuses the brain and nausea sets in.
Battling through sea sickness can be helped by pharmaceuticals, psychology or nature. For the lucky ones, it will often disappear after a couple of days as your brain adjusts to the ever-moving environment and your ‘sea legs’ develop.
Our instructor Rachel and her rowing partner Lin, decided not to take any medication for their Atlantic row. Both suffered sea sickness in the first 36 hours with nausea and vomiting. They did find that lying down or rowing were fine, it was just anything in between that caused a problem! But it passed quickly and they were fine for the rest of the voyage. Interestingly, Rachel now suffers from mild land sickness and often feels dizzy and a little nauseous after even a short time on the water.
In addition to the inner ear, other factors that can contribute to sea sickness include blood flow, heart rhythm, hydration, sinuses and psychological factors such as excitement, nerves and fear.
Mind over matter can work for some. One sailing instructor is reported to tell students that if they hold a potato in their left hand they won’t get sea sick! Bizarrely it works for most and if you’ve ever had sea sickness, you’ll most likely give anything a try!
Some common triggers for sea sickness include:
- Hydration. Avoid alcohol and stay hydrated. Even if you vomit repeatedly, try to drink in between as it can ease the nausea and you will absorb some.
- Food. An empty stomach, or eating spicy, fatty or acidic food mean that your stomach is more likely to react badly to any nausea. Vomiting with something in your stomach is much better than vomiting on an empty stomach.
- Fear. Even in difficult conditions, try to stay calm. Anticipation of being sick can bring it on and being ill just adds to the problems.
- Temperature. Extreme cold or heat can cause nausea. Try to adjust your layers according to the temperature and be ready for temperature changes.
- Fatigue. Make sure you and your crew are well rested before departure. Plan shifts to allow for illness.
Sea Sickness Remedies
- There are many drugs available that can address the issue so it’s best to speak to a Doctor or Pharmacist to find the right one for you. But , it’s worth remembering that many drugs suppress the symptoms of sea sickness, so while they are ideal for a day sail, may not be as effective if you’re at sea for longer as symptoms can still happen if you stop taking them.
- There are also lots of non-medical remedies such as acupressure wrist bands, patches, and sea glasses that might be worth a try.
- Avoid dehydration and muscle spasms by staying hydrated before and during your voyage. Avoid alcohol if possible. Have drinks handy at all times including bottles of water in the cockpit.
- Eat. Even if you vomit it back up - it’s better to have something in your stomach. Ginger is recommended - ginger biscuits, ginger snaps, ginger tea, raw ginger, ginger sweets or ginger ale. Peppermint can help, or even a small amount of toothpaste on the tongue can ease the nausea. Rachel recommends tinned fruit in syrup on the basis that it goes down (and up!) easily and the glucose in the syrup helps keep energy levels up. Eat things that will taste the same on the way back up and not leave a yukky taste in your mouth, for example, an apple versus tuna or dairy products which could add to the nausea.
- Try to avoid strong smells such as diesel, the head, the galley.
- If you start to feel nauseous, distract yourself. Take the wheel or carry out a task that requires concentration. Stay on deck in the fresh air if possible, and focusing on the horizon can help your brain to figure it out. Standing or lying are better positions than sitting.
- Lie flat in the centre of the boat where movement is reduced. Avoid the bow. Sleeping on the floor instead of a bunk can reduce motion.
- Try to sleep and rest when you can, even if you don’t feel tired. Sleeping onboard the night before departure can help your brain to figure out the motion.
- Try the trick with the potato in your left hand! Mind over matter can work and it will give the rest of the crew something to laugh about!
- If fear is a factor, try not to let it take over. Trust your skipper and crew, the boat and yourself. Reassure yourself that things can work out well. Research before setting off can help.
- Focus on the positives. The things you love about being out at sea and the things that make it enjoyable for you.
- Plan shifts and allow for illness. Think about the skill mix of those onboard and shortening shifts if necessary.
- Prepare meals in advance if it’s likely to be rough, so you can grab food on the go and minimise time below deck.
- Challenge yourself with a goal, such as trying to make every watch, to provide a sense of achievement even if you’re feeling rotten.
- Use something solid to provide balance, keep your legs shoulder width apart and offset the boat movement with your body - like using a hula hoop.
- If you know you’re prone to sea sickness, accept it might happen and focus on the things you know will help and how you’re going to fight through it to calm your nerves and fear.
Finally, if you are going to be sick, make sure you head to the down wind side!!!
Welcome to our latest guest blog where we’ve been chatting to James Griffiths, General Manager of Ocean Operations for Scenic Group and finding out more about what happens behind the scenes in order to keep a fleet of luxury expedition ships running. Here’s what James told us… As General Manager of Ocean Operations, I’m responsible for the operations of our fleet which includes four ships in service with around 850 colleagues. I currently live in Mumbles, near Swansea in the UK, but due to the nature of my work I spend a significant amount of time living in Croatia. Prior to this role, I spent many years working at sea and worked up through the ranks to Captain and over the last 15 years, my main focus has been on polar expedition travel. I hold a master mariner certificate of competency in addition to a degree in engineering and a post graduate diploma in law. Part of my job is to work with our medical service provider (Red Square Medical) to ensure that our ships are offering medical services that are appropriate for their deployment, and this can often be to some of the most extreme and remote locations around the world. It’s extremely varied, though during the COVID-19 pandemic, I came ashore when our operations paused for a significant period of time. I was fortunate enough to be given the opportunity to lead the restart of our Ocean Operations, which included setting up everything from a company to manage the ships, to selecting our crewing, medical, helicopter and submarine partners and providers, amongst many other things. Our areas of operation, and the nature of our cruises (expedition), plus having aircraft and submersibles onboard some, do mean additional elements involved in the management of these ships. You could say that this current position is more of a happy coincidence than one that I actually planned for! In some ways this is a great positive - I do think it’s possible to plan a little too much and then be disappointed if things don’t go quite the way you had imagined. But there’s no danger of that here!
Back in February 2022, we brought you one of our very first guest blogs from Simon Lawton, a Paramedic who has swapped out his ambulance for a Superyacht! You can read the original blog here: https://www.redsquaremedical.com/superyacht-paramedic-a-guest-blog-from-simon-lawton Over the last 2+ years, we’ve followed Simon’s career, and some of you may even recognise him as he does put a Red Square Medical instructor hat on from time to time. But, as for all healthcare professionals, Simon has to keep his skills up to date. So, we asked him to tell us a bit more about how he juggles this along with a rota onboard. Here’s what he told us… I’m originally from Stoke-on-Trent in the UK and trained as a HCPC registered Paramedic. I’ve spent almost 5 years working at sea now, with almost continuous employment on three different vessels, after leaving the ambulance service in 2019. My first role was as a Paramedic/Deck hand on Superyachts, and I now work as a Medical Officer on a maritime vessel. Even before I applied to become a Paramedic, I intended to complete my studies to help find employment in a remote or offshore environment. I had always been attracted to the idea of being able to travel the world while earning a salary. Working at sea has meant that I have travelled extensively, earnt a higher salary, and have a better work/rest balance than would be possible in a role on land. Note: At the time of writing, a qualified Paramedic’s starting pay in the UK was £28,407 and Simon’s old rota was 2 days, 2 nights (all 12 hours) and 4 days off with very inflexible annual leave. This year I decided to carry out some continual professional development (CPD) at a hospital in Mexico, to keep my skills up to date. I was interested in travelling to find out more about how healthcare services are provided outside the UK and Europe. The CPD activity in Mexico allowed me to do exactly that, while caring for and treating a wide variety of patients who had either self-presented in the emergency department, or been conveyed to hospital by ambulance.
Welcome to our September blog, and as we all start (in the UK at least!) to think about adding a few layers for warmth, we’d like to talk about getting naked! Well, to be more specific, getting bra’s off. Fact: Women are dying because bystanders are less likely to carry out CPR on women than men. Research shows that women are 27% less likely to receive CPR than men and if a defibrillator is used, their chance of survival is affected by bra’s being left on. Most of us have never had the chance to train using a female manikin. The #BraOffDefibOn campaign aims to address the inequality in CPR for women and we’re supporting it.
In August, we brought you a Guest Blog from Mark Hannaford, the founder of World Extreme Medicine. This month, it’s the turn of another of the key WEM faculty members… introducing Dr Will Duffin. Hello everyone, I’m Dr Will Duffin and I’m a GP in Devon in the UK. I’m the Joint Medical Director of World Extreme Medicine (WEM) and the Lead Medic for the US CBS TV show ‘Survivor’ - for Seasons 43, 44, 46 and 48, which is also through WEM. Extreme Medicine is healthcare that is delivered across the full spectrum of remote, austere and challenging environments. This includes high mountains, deep oceans, jungles, deserts, polar, low earth orbit and refugee camps… the list is endless. Being a part of the wider Extreme Medicine community through WEM has been a portal into new worlds of possibility and opportunity in my medical career as an NHS GP. It’s a huge privilege to treat patients in a remote setting. You get to do proper ‘hands on’ medicine that truly tests your clinical skills, risk management and decision making. Even basic techniques and principles done well can transform patient outcomes. That’s the big reward. I graduated from Bristol Medical School in 2008 and completed my GP Training in Cornwall, UK in 2016. In between, I spent 18 months in Australia to gain as much emergency department experience as I could, whilst doing Wilderness Medicine Courses. I landed my first expedition gig 12 years ago when I was post-FY2 (Foundation Years follow on after qualifying as a doctor). I covered a Kilimanjaro Trek after another doctor dropped out at the last minute. Once I had this under my belt, I was able to leverage this experience to get the next trip. So, I soon found myself providing regular medical cover for various commercial and charity sector expeditions. These expeditions have taken me all over the world: Kilimanjaro, the Peruvian Andes, the Himalayas, Northern China, Eastern Europe, Myanmar and Madagascar. One highlight was working as the private doctor for a Luxury Trans-Siberian Train! Though I became frustrated having to constantly wrangle annual leave to go away, so I made the switch to being a freelance (locum) GP, which has given me the flexibility I need. I joined WEM in 2018 after responding to a Facebook Ad for the ‘Survivor’ job. I was invited to a selection weekend in the Peak District, which is when I first met Mark Hannaford WEM founder and CEO and Dr Joe Rowles, WEM’s other Medical Director, and it all went on from there. Early on, I was given the opportunity to lead on the content for the annual World Extreme Medicine Conference and our various podcasts and webinars. Through doing this, I have met a colourful cast of characters; other extreme medics who are as audacious as they are inspirational! We have a lot of fun at the conference every year, learning from one another. https://worldextrememedicine.com/registration/wem-conference-2024 (Note from the RSM team – the conference is highly recommended and well worth a visit!)
Last year, the Red Square Medical team descended on the World Extreme Medicine (WEM) conference for the very first time. We’d been aware of this unique organisation for many years, but just not had the chance to get involved. Liz was involved in a panel discussion and spoke at the conference, and we came away literally buzzing with enthusiasm - our first impressions were that WEM is a place with no ego’s, where everyone wants to learn, and is willing to share. We met some of the most fascinating people ever and can’t wait to go back this year. But what about the person who started it all… We spoke to Mark Hannaford, founder of World Extreme Medicine and its far reaching impact. Here’s what he had to say. I’ve been involved in expeditions, working in low resource environments and extreme medicine for the past three decades! My family was made up of generations of seafarers from Cornwall although I was brought up variously in Devon, Antigua in the Caribbean and the Middle East; reflecting my father’s job as a Master Mariner. My father was at one time the youngest captain aboard the UK’s largest registered vessel, and my grandfather was Harbour Master for Malta and the first in that role in Plymouth at the start of Queen Elizabeth’s reign. I wear a number of hats but primarily I am the founder and CEO of World Extreme Medicine, and the annual WEM Conference. I also founded the MSc in Extreme Medicine at the University of Exeter and Graduate Certificate program at Bouvré College of Health Sciences, Northeastern University, Boston.
Women’s health is a huge topic, while it’s true that in the maritime sector women make up just 2% of seafarers at sea, up to 34% of the shore based staff are female. Looking at the bigger picture, women’s health directly affects just under half of our population globally, and indirectly (whether you like it or not!) the other half, we thought it was worth a blog about some of the issues, and the taboo’s, that could be affecting our maritime workforce and the women in our lives. It's common knowledge that women experience huge hormonal changes at puberty and menopause, both of which can have significant physical and mental health impacts. In the UK, there is a growing discussion and openness about peri-menopause (the years before periods stop altogether) and how for some women, this has devastating effects across all aspects of their lives, including work. Of course men experience changes at puberty, but their later life changes are less significant and generally don’t affect their ability to work. In December 2023 the World Health Organisation (WHO) issued a statement to advise that every year, at least 40 million women are likely to experience a long term health problem caused by childbirth. So there’s a good chance that we all know one or more women affected, or if you are female… this could be you. As part of a special series on maternal health, the study showed a high burden of postnatal conditions that persist in the months and years after giving birth. These issues include more than a third of women experiencing pain during intercourse, urinary incontinence (8-31%), anal incontinence (19%), anxiety (9-24%), depression (11-17%), perineal pain (11%), a fear of childbirth (6-15%) and secondary infertility (11%). All in all it doesn’t paint a great picture of life after childbirth for some women. If any of your workers experience these issues, either on or off shore, it could have a significant impact on areas of their working life and it’s something they may be reluctant to open up about. Even before childbirth, we may take it for granted that contraception is available, certainly in the developed world. But in developing countries where sexual violence is not uncommon, contraception is considered lifesaving due to the high level of unsafe abortions carried out. Around 13 million women (and girls) under 20 give birth annually and complications in the pregnancy and birth is a leading cause of death. Consequently abortion is an option, but this carries its own huge risks.
We just love speaking to and finding out more about the people who inspire us and we guarantee that this month’s blog will not disappoint! We first got in touch with Wendy Sullivan via LinkedIn and thought she seemed like a pretty awesome human. Wendy and her company, Maritime Medical Solutions in Australia, certainly share the same outlook as Red Square Medical. Fast forward a couple of years and we’re now collaborating on a project in Australia and the Pacific Islands. What we’ve learnt along the way is simply fascinating and Wendy has kindly agreed to share her story with us… Here is Wendy’s Guest Blog: I was born in Canada, grew up in Africa and now call Australia my home. I feel lucky to live in paradise where the weather allows us to be on the water year-round. I had to work hard to gain my Australian citizenship and I credit my work in the marine industry with giving me a pathway to stay in Australia permanently. It took years of hard work and uncertainty to gain my residency and is still one of the achievements I am most proud of. I started sailing in Canada and since emigrating to Australia gained my professional and commercial qualifications as a vessel master, marine engine driver, trainer and assessor. I also have a Diploma of Paramedical Science, ship masters medical qualifications, business administration and development and there is still so much more to come.
Working at sea can be one of the most rewarding and fulfilling careers. But you can’t gloss over the fact that it can be dangerous. Whether you’re working on a tanker, ploughing up and down the oceans, a Superyacht enjoying a busy season of charters, or any vessel in between; our love/hate relationship buddy Neptune takes no prisoners! The Safety of Lives at Sea (SOLAS) Convention in its successive forms is generally regarded as the most important of all international treaties concerning the safety of merchant and other vessels. The first version was adopted in 1914, in response to the Titanic disaster, and went through several iterations up to 1974. The Convention in force today is generally referred to as SOLAS 1974, as amended. SOLAS regulations cover all areas of safety at sea, including construction, fire prevention and detection, life saving equipment, cargo carriage, navigation, communications and a host of other areas. Regulation 33 of the SOLAS Convention applies to all ships, and places an obligation on Masters to respond to distress calls at sea and proceed ‘with all speed’ to their assistance. Anyone working in the maritime sector, hopes that they are never on the receiving end of this regulation, but we’ve experienced two quite different instances, where the ships we work with have responded and our Medical teams have played an important part in rendering aid.
This week’s blog is an introduction to telemedicine as although it’s probably been around for longer than you think, you might not be familiar with what’s available to help you. So whether you’re a leisure sailor taking on the ARC; work in commercial shipping, spend your time on a Superyacht, or anything in between, read on for more information… According to the UKs National Institute for Clinical Excellence, (NICE: https://www.nice.org.uk/), ships being on the water for months at a time mean that health can be a life-threatening challenge for sailors and seafarers. Access to healthcare providers has always been one of the most critical issues for offshore crews and it’s worth remembering that the International Labour Organization (ILO), dictates that access to medical treatments and health services should be guaranteed to seafarers in the same way as for people working ashore. Nowadays, telemedicine technology has emerged to improve healthcare delivery in many remote areas where there is no direct access to healthcare services using telecommunication services. Among them, maritime Telemedical Assistance Services (TMAS) have become more readily available and are now considered an integral part of a shipowner's emergency response operations. The advent and uptake of Starlink in both the commercial and leisure sectors can only be a positive from a medical perspective. So, what is Telemedicine? What does it do and how does it work? Telemedicine is a term that’s becoming more and more common in the maritime world. Quite simply, it is the provision of remote clinical services, via real-time two-way communication between the onboard medic (trained crew or healthcare professionals) and/or the patient themselves, and a shore-based healthcare professional, using electronic audio and visual means. The modern history of Telemedicine can be traced back as far as 1905, when a Dutch physician used long distance transfer of ECGs (electrocardiograms) to be read remotely. But as early as the 1920s onwards, radio communications were being used to pass medical information to patients at sea on ships and on remote islands. More recently, the COVID-19 pandemic has brought Telemedicine to the forefront of healthcare. Though we may not easily recognise what it actually is, the majority of GPs (certainly in the UK) and other allied healthcare professionals in the non-acute world, such as Physiotherapists and Mental Health support, have relied heavily on telephone and video consultations since March 2020. A survey conducted by Nautilus International and Martek Marine (2017) showed that a staggering 98% of seafarers believed that greater access to Telemedicine support would save lives at sea. Of those questioned, 68% had been on a vessel that was forced to divert due to a medical emergency and 70% had been on a vessel where there had been a medical evacuation. Emergencies experienced at sea ranged from severed limbs and broken bones, to gunshot wounds, tropical diseases, allergic reactions and sudden cardiac arrest. Whether you’re a commercial seafarer or leisure sailor, it would improve confidence in making a decision on whether an injury, or illness was severe enough to warrant a diversion, or evacuation, if there was a trained medic on the end of the phone or radio. Ever improving communications also means that we can now go far beyond voice calls. Photos of injuries, files of test results and even live streaming is all possible and helps to provide a much more indepth service. Our own team member, Rachel, received Telemedicine support via SatPhone and email, on a 7 metre Ocean Rowing Boat (yes, you did read that right!) in the middle of the Atlantic, when her rowing partner developed a painful injury. Remote intervention from a Doctor onshore helped to maximise use of the medical kit contents for the short and long term, rule out immediate worries of infection, and develop a pain management plan for the rest of the rowing race. One in five commercial ships a year are forced to divert for a medical emergency, with unknown numbers of other, non-commercial vessels on top. So there is also consideration for the cost and time involved, plus the stress to both the patient, and their medic who is managing a situation onboard, possibly alone!
At Red Square Medical, we’re keen to support those who have a passion for maritime medicine. While we can’t provide placements for everyone, occasionally a request pops up at just the right time and we can provide some experience and insight into our unique and specialised world. Last year we were contacted by Jordan Lin, a medical student with a love of the ocean. This is his story… When I was a boy, my dad and I used to go fishing with a local fisherman off the Norfolk coast. I absolutely loved being on the sea and so for quite a long time, I wanted to be a fisherman. When I got a bit older I kind of forgot about this and think I may have been slightly put off by watching the TV series ‘World’s Deadliest Catch’! But I have always loved being on the water and spent a lot of time sailing dinghies; I was also a swimming teacher for children back in high school and college. Later, I decided to study medicine and I’m now a final year medical student at the University of Bristol where I completed an intercalated degree; a Masters in Health Sciences Research. I’m now looking forward to starting work as a qualified Doctor in August. Though having spent 6 years training, my next 2 years will be spent working for the required two foundation training years that must be completed before being able to work independently as a Doctor in the UK. At university, I joined the VITA network which is a group dedicated to developing a health and public health approach at the heart of any response to human trafficking and exploitation. I became the blog coordinator for the organisation and you can read the blogs, including those that I have written, here: https://vita-network.com/blog/ In my spare time, I have been involved with the Bristol University Hot Air Ballooning Society and trained through the society to get my Balloon pilots licence. So, I often spend weekends during the summer flying in a leisurely fashion over Bristol and the surrounding area!
