Fit for purpose: Practical health and fitness tips for seafarers

Life at sea isn’t exactly a wellness retreat. Between long hours, heavy work, and unpredictable schedules, it gets easy to forget that health should be a priority. However, being fit and well isn’t just about feeling good, it is about staying safe, alert, and ready for the job, notes Maria Kostala for The American P&I Club.

Seafarers don’t need extreme routines. Just a few practical, familiar habits, like eating better, drinking enough water, and moving more, can make the difference on board.

Let’s take a look at what works, and why it matters

#1 Balanced Diet: Making the Best of What’s Available

The Plate Method

The menu onboard might not win awards, and yes, the same dish can feel like it’s chasing you across oceans. But even with limited or repetitive options, smart choices can go a long way.

A helpful guide is the Plate Method, simple, visual, and surprisingly practical, even at sea:

• Half your plate: Vegetables or salad, fresh, frozen, steamed, pickled. You can refill the salad portion as many times as you wish.
• One quarter: Protein i.e. meat, chicken, fish, eggs, legumes (lentils, chickpeas, beans, etc.), dairy (cheese, yogurt, milk or kefir).
• One quarter: Carbohydrates i.e. rice, pasta, potatoes, bread (if available, go for the wholegrain options such as brown rice, whole wheat bread etc. these are not only healthier but will keep you full for longer).

The best combo

Whenever possible, try to include all major food groups in each meal even when snacking:

• Protein for strength and muscle repair
• Carbohydrates for fuel
• Healthy fats like olive oil, seeds, nuts, or oily fish for brain and heart health
• Something fresh, either fruit or vegetables in any form, for fiber and nutrients

Intuitive Eating

It also helps to eat intuitively, that means listening to your body. Eat when you are hungry, but not “hangry” (so hungry that you feel irritated). Stop when you are full and satisfied, not stuffed. Ideally, dietitians recommend stopping before you feel completely full but let’s be honest, that is easier said than done, so I won’t insist on this one. However, remember not to finish every plate out of habit, boredom, or loneliness

The 80/20 Rule

We should not label foods as “good” or “bad”. You can eat everything you enjoy, just aim for moderation. A basic and useful rule of thumb is the 80/20 approach: eat healthy, balanced meals 80% of the time, and enjoy treats or comfort foods the other 20%.

Food should nourish both your body and soul. It should keep you going and at the same time bring you joy. A happy, balanced meal is one you look forward to. 

#2 Hydration: The secret weapon

Dehydration can show up as fatigue, headaches, poor focus, or even dizziness. With air conditioning, salty food, and hot workspaces, seafarers can get dehydrated quickly.

It is best to prevent it:

• Keep a water bottle with you when possible and refill it often.
• Drink regularly, not just when you are thirsty, you can even set a reminder.
• Limit sugary and energy drinks which don’t provide proper hydration.

Even mild dehydration affects your ability to work safely and your long-term health, so don’t wait until you are or even feel thirsty to drink. An average adult needs around 2.5-3 liters or more of fluids daily, especially in hot conditions or during physical work, so make sure to stay on top of your water intake.

#3 Fitness: Move when you can, however you can

Regular movement helps you stay strong, mobile, and healthy.

Try:

• Using the gym if available. Extra bonus, if possible, to organize an exercise group with coworkers. Fitness buddies can make a difference.
• Bodyweight exercises in your cabin: squats, push-ups, planks, even 15 minutes per day count. You can create a basic routine and rotate it weekly to ensure that all muscle groups are equally exercised.
• Stretching after your shift, or even during breaks, if possible.
• Be intentional about your steps. Space is limited onboard, so you may need to find creative ways to walk more. Every step counts, and they add up quickly.

If, during port calls, shore leave is allowed, take the chance to walk long distances work/weather/schedule permitting. Explore on foot, breathe fresh air, and enjoy fresh local foods or produce, it’s good for your body, mind, and morale and extra bonus: you explore different cultures.

#4 Connect and Unwind Time

Fatigue is more than tiredness and can be either physical or mental or even a combination of both; it slows reaction time and thinking. Add isolation or homesickness, and it can build up even leading to burnout.

What helps:

• Stick to a sleep routine when possible. Try to get at least 8 hours of sleep per day, even in combination with naps.
• Engage with the rest of the crew; sometimes a simple chat over coffee can make a big difference.
• Keep in touch with your friends, family and loved ones ashore; regular communication can assist in maintaining the connection despite the distance.
• Do things that recharge you often: a phone or video call back home, a game with the rest of the crew, a good read, a warm cup of tea, or even keeping up with a hobby, if possible.

Mental wellness is part of staying safe, healthy and effective. A connected, rested, happy crew is a stronger crew. 

#5 From safety’s point of view: Health VS hazard

From a safety and loss prevention perspective, a healthy crew is a safer crew:

• Staying well-hydrated, rested, and properly nourished helps reduce the risk of errors and injuries.
• Being physically fit improves performance.
• Good health supports faster reaction times, clearer thinking, and better teamwork.

Taking care of yourself isn’t a luxury, it’s part of doing your job safely and professionally and living the life you deserve.

#6 Health is a shared responsibility

While seafarers can do a lot through personal choices, it’s easier to stay healthy within a supportive environment. Thus, the companies could assist in several ways, some ideas to follow:

• Access to varied, nutritious provisions and healthy choices when possible.
• Basic properly equipped space and time for physical activity.
• An idea would be providing the option to attend online meetings with dietitians and gym coaches on a regular basis i.e. once per month, so that the crewmembers can track their progress and be supported in their nutrition and exercise goals.
• In addition, offering access to confidential online consultations, via phone or video call, with trained professionals could provide support and relief in case of mental discomfort, stress, or emotional challenges.

Healthy habits are much easier to maintain when the onboard conditions make it possible. Seafarers should know that they are not alone in this. 

Final thought: Small habits, big impact

You don’t need to be perfect. Just consistent.

Eat better when you can. Move intentionally. Drink enough water. Sleep well. Enjoy your meals. Connect and support each other.

Afterall, the most important and most precious piece on board isn’t the rudder, radar, or engine; it is you.
