Taking a 5-day cruise holiday is officially good for your health – here’s what it improves

Groundbreaking neuroscience research aboard Cunard’s iconic Queen Mary 2 has confirmed what seasoned travellers have long known: just five days at sea can significantly enhance cognitive abilities, including memory, logical reasoning, perceptual skills and problem-solving.

The study reveals that Cunard’s legendary Transatlantic Crossing isn’t just a journey — it’s a voyage toward improved mental and emotional wellbeing. Where can we sign up?

In a pioneering study conducted by the Human Understanding Agency and Walnut Unlimited, researchers explored how Cunard’s Transatlantic Crossing impacts the mind and body. Forty guests from around the globe embarked on the classic voyage from Southampton to New York, with biometric tools capturing their cognitive and physiological states before and after five days at sea.

The findings were extraordinary – here’s what the seafarers saw improve:

– Memory: Word recall improved by an impressive 29 percent, highlighting enhanced short-term memory.
– Problem-solving: Complex logical and spatial reasoning skills soared by 125 percent.
– Attention: Visual task focus increased by 14 percent.
– Relaxation: Self-reported relaxation surged by 158 percent, while stress hormone levels decreased by 35 percent.

Dr Jack Lewis, a neuroscientist involved in the study, remarked: “What stands out for me in this study is how neatly all the pieces fit together. The passengers’ time on the ship clearly reduced their stress levels, based on subjective and objective measures.

“The main stress hormone cortisol is well-known in the science research literature to interfere with various cognitive processes. So the boost in memory and logical reasoning capacity identified in this study is likely to be attributed to the stress-relieving impact of ocean travel.

“This combined with the amazing array of stimulating activities onboard the world’s only ocean liner, allows the passengers’ brains to unlock their full potential.”

Like most cruise holidays, Cunard’s voyages are more than just swanky escapes — they’re crafted experiences designed to nurture the soul. Onboard Queen Mary 2, guests can immerse themselves in lectures from world-class experts through the Cunard Insights programme, indulge in bespoke wellness treatments or simply unwind in the ship’s tranquil ambience. A cheeky prosecco or two probably helps, as well – all complemented by Cunard’s celebrated White Star Service.

Katie McAlister, President of Cunard, reflected on the study’s findings: “This study reinforces what we have always known – a Cunard voyage is much more than just a holiday.

“Our thoughtfully curated enrichment programmes, bespoke wellness experiences, world-class dining, and renowned White Star Service combined with the opportunity to unwind and embrace the serenity of the ocean, leave our guests feeling refreshed, inspired and reinvigorated.”

The research from Cunard comes hot on the heels of the announcement that the line is collaborating with renowned Michelin-starred chef Nathan Outlaw. This partnership brings the famous Outlaw’s Fish Kitchen to life aboard select Queen Victoria Mediterranean voyages.

Cruise with famous chefs in 2025

In summer 2025, guests aboard Queen Victoria will have the opportunity to indulge in exclusive dining events personally overseen by Nathan Outlaw. The highlight will be a series of intimate, five-course seafood tasting menus, showcasing the freshest Mediterranean ingredients and Outlaw’s signature culinary artistry. With only 60 guests per event, these dining experiences promise a splendid fusion of fine cuisine and the stunning backdrop of the Mediterranean coast.

The collaboration features four residencies of Outlaw’s Fish Kitchen during Queen Victoria’s Mediterranean season. The series begins on July 7, 2025, with a 14-night voyage from Barcelona to Rome. Outlaw will be onboard for the first seven nights.

In addition to the dining experiences, Outlaw will engage guests through live cooking demonstrations and intimate Q&A sessions as part of Cunard’s Insights programme. These events will offer a behind-the-scenes look into his culinary philosophy and rise to fame as one of the world’s leading seafood chefs.

This partnership follows Cunard’s August announcement of a reunion with Michelin-starred chef Michel Roux for the Le Gavroche at Sea series, set to elevate four Fjords voyages in 2025.
