Sleep, food, movement and small habits that keep crew well for a whole contract.
To stay healthy at sea, protect your sleep, eat properly in the crew mess, move every day, wash your hands often and speak up early when something feels wrong. None of that is complicated. The hard part is doing it for 6 to 9 months while you work around 10 hours a day. Over a long career at sea, I watched the crew who treated their health as part of the job last longest.
Protect Your Sleep First
Sleep is the first thing to go on a ship and the first thing you feel. Hours are regulated under the Maritime Labour Convention, which sets minimum rest periods, but those hours can be split into short blocks. You can end up with a few hours here and a few hours there.
Treat your rest time as part of your shift. Go to bed when you can, not when your cabin mate wakes up. Use an eye mask and earplugs. Skip the late night in the crew bar before an early start. If your rest hours are being cut below the legal minimum, tell your supervisor. Rest hours are recorded for a reason.
Eat Well in the Crew Mess
The crew mess serves a lot of food, and it is free. That is both the good news and the trap. Plenty of new crew gain weight in the first contract because every meal is available and nobody is counting.
Build a simple routine. Start with protein and vegetables, then add carbohydrates. Keep sugary drinks to a minimum. Drink water through the shift, especially in hot galleys and on deck. If you have a dietary need, tell the crew mess team early; they cannot guess. And remember, F&B is the largest department on any ship, so the people feeding you are professionals who like being asked.
Keep Moving When You Stay Healthy at Sea
Many ships have a crew gym. Use it, even for twenty minutes. If your ship has no gym, use stairs, stretch before bed and walk the crew deck. Exercise helps your sleep, your mood and your back, which takes a beating from long shifts on your feet.
Do not train hard right before a shift. A short, regular session beats a heroic one you skip next week.
Wash Your Hands, Every Time
Ships are close quarters. A cabin, a corridor and a crew mess are shared with hundreds of people from over 40 nationalities, and an illness moves fast. Cruise lines take hygiene seriously for good reason.
Wash your hands before you eat, after the bathroom and after handling shared equipment. Follow your department's hygiene rules without shortcuts. If you have a stomach illness or a fever, report it and stay away from food and guests until the medical team clears you. Hiding it puts everyone at risk, and you will usually recover faster with proper rest.
Look After Your Mind Too
Staying well at sea includes your head. Long contracts, little privacy and time away from family wear people down. Keep a call schedule with home, get out of your cabin and spend time with people you like. If you feel low for more than a couple of weeks, talk to your supervisor, Crew Services or the ship's medical team. Our article on cruise ship homesickness has more on this.
Use Your Port Days Wisely
When shore leave is possible, use it for fresh air and movement. Wear sun protection, drink water and do not rush back on an empty stomach. Port days are also the best chance for a strong phone signal and a proper call home. Shore leave is a bonus, not a guarantee, so do not plan your whole health routine around it.
Know What Medical Care You Have
Before you sign, you need a seafarer medical certificate once your contract is confirmed. On board, the medical centre is staffed by doctors and nurses, and crew can use it for illness and injury. Ask your manning agency what your contract says about medical care and how it works in your case. For general guidance on healthy habits, the World Health Organization is a reliable source.

Do cruise ships have a gym for crew?
Many do, though size and equipment vary by ship and cruise line.
What should I do if I feel unwell on board?
Tell your supervisor and visit the ship's medical centre. Do not work around food or guests while you are ill.
