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

Cunard has revealed how undeniably improving a cruise holiday can be good for your health – and its cool findings are all backed by science.

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?

How can a cruise improve your health?

Brain power

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.”

Happy hours

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.”
