Retinol creams may get all the glory in the war against wrinkles, but researchers at Edith Cowan University (ECU) have identified a far more enjoyable anti-aging strategy: going on vacation. In a 2024 study published in the Journal of Travel Research, the team applied the theory of entropy - the universe's relentless march toward chaos - to tourism, suggesting that positive travel experiences might help the body maintain order and resilience, potentially slowing some signs of aging. No, it won't stop the clock, but it frames that trip to the beach as more than just an excuse to overpack.
Lead author and PhD candidate Fangli Hu explained that aging is irreversible but can be slowed. Travel, she argued, places people in new environments, encourages movement, boosts social interaction, and generates positive emotions - all things that wellness tourism, health tourism, and yoga tourism have been quietly cashing in on for years. "Tourism isn't just about leisure and recreation," Hu said. "It could also contribute to people's physical and mental health."
The study proposes that positive travel experiences may influence four major body systems: they can stimulate the adaptive immune system, reduce chronic stress, encourage physical activity (like walking through cities or hiking trails), and even release hormones that aid tissue repair. "Put simply, the self-defense system becomes more resilient," Hu noted.
Since the 2024 paper, related work has continued. A 2025 research note by Hu and colleagues described travel therapy as an emerging approach, while another 2025 paper called for closer collaboration between travel medicine and tourism. A systematic review from the same year found that tourism and healthy aging is a growing but underexplored field. The catch? Travel isn't automatically healthy. Tourists can face infectious diseases, accidents, and unsafe food - or, as Hu pointed out, "the public health crisis of COVID-19." So the message isn't that any trip will slow aging, but that safe, restorative, active vacations might help you age better from the inside out. You know, if you can afford one.
