A neuroscience study aboard Cunard’s Queen Mary 2 suggests that slow sea travel can significantly enhance cognitive function and reduce stress. Conducted by Walnut Unlimited, the research monitored 40 passengers during a transatlantic crossing from Southampton to New York, employing neurofeedback and biometric devices to track cognitive and physiological changes over five days.

Guests’ cognitive abilities were assessed both before and after spending five days at sea.

The findings were striking: passengers showed a 29% improvement in short-term memory, a 125% increase in logical and spatial reasoning, and a 14% boost in focus during visual tasks. Reports of relaxation surged by 158%, while physiological stress dropped by 35%, indicating the calming effects of extended time at sea. According to neuroscientist Dr. Jack Lewis, the reductions in cortisol—a primary stress hormone—likely contributed to the observed cognitive gains.

Katie McAlister, president of Cunard, highlighted how the company’s enrichment programs, wellness experiences, and renowned White Star Service amplify the benefits of ocean travel. “This study reinforces what we’ve always believed—a Cunard voyage is much more than just a holiday,” she said. Guests leave feeling refreshed and inspired, demonstrating that the serenity of the ocean, combined with carefully curated onboard experiences, can deliver profound mental and physical benefits.
