An interdisciplinary study examining tourism through the lens of entropy theory suggests that positive travel experiences involving movement, relaxation and social connection may support healthier aging.

Researchers at Australia’s Edith Cowan University are examining whether travel may play a larger role in human health than previously understood, with a recent interdisciplinary study proposing that positive tourism experiences could help slow aspects of the biological aging process.
The 2024 study, published in the Journal of Travel Research and later highlighted by ScienceDaily on May 4, 2026, applied the concept of entropy — the gradual movement toward disorder within physical systems — to human aging and travel behavior. Researchers concluded that travel experiences combining physical activity, novelty, stress reduction and social engagement may support bodily systems associated with maintaining health and resilience over time.
“Aging, as a process, is irreversible. While it can’t be stopped, it can be slowed down,” Edith Cowan University PhD candidate Fangli Hu said in a statement. “Tourism isn’t just about leisure and recreation. It could also contribute to people’s physical and mental health.”
The researchers used entropy theory as a framework for understanding how environmental and behavioral experiences influence aging. In biological systems, entropy is associated with the gradual loss of cellular organization and physiological function. The ECU team proposed that positive travel experiences may help slow the increase of entropy within the body, while stressful or harmful travel experiences may accelerate deterioration.
The theory parallels ideas discussed in Rose J.G.’s book “The Youth Factor: How to Live to 120 Years,” which explores scientific interpretations of entropy as a contributing factor in aging. The book notes that living organisms continuously replenish order through nutrition and energy exchange with their surroundings.
Tonya Zavasta, author of “Quantum Eating: The Ultimate Elixir of Youth,” similarly describes the body’s effort to resist entropy through environmental interaction. “Life retains a high level of orderliness by continually sucking orderliness from its environment,” Zavasta writes, citing sunlight and plant-based nutrition as examples of external order-supporting forces.
The ECU study extends this concept to travel, suggesting that exposure to new settings, enjoyable experiences and restorative environments may help support physiological balance.
According to the researchers, positive travel experiences may influence several critical systems associated with aging, including immune function, metabolism, stress regulation and tissue repair. Exposure to unfamiliar environments may stimulate adaptive responses within the body, potentially strengthening resilience and promoting biological maintenance processes.
Hu said these experiences “may prompt the adaptive immune system,” referring to the body’s ability to recognize and respond to external threats. “Put simply, the self-defense system becomes more resilient. Hormones conducive to tissue repair and regeneration may be released and promote the self-healing system’s functioning,” Hu added.
Researchers also pointed to the role of physical activity commonly associated with travel. Walking, hiking, cycling and other movement-based activities may improve circulation, nutrient delivery and metabolic health while supporting the body’s repair mechanisms.
Broader health research has consistently linked regular physical activity to improved aging outcomes. A 2020 article summarizing fitness studies noted that exercise supports sleep quality, cardiovascular health, metabolic regulation and mental well-being. Travel-related movement, while often less structured than formal exercise programs, may still contribute to those benefits through increased daily activity and weight-bearing motion.
The study also highlighted the relationship between chronic stress and aging. Long-term stress exposure elevates cortisol levels, which researchers have associated with immune suppression, cognitive decline and structural brain changes.
In “Genius Foods,” author Max Lugavere wrote that chronic cortisol elevation can reduce brain-derived neurotrophic factor, or BDNF, while contributing to degeneration in vulnerable brain regions such as the hippocampus. Researchers suggest that restorative travel experiences involving relaxation and social connection may help counter some stress-related physiological effects.
Moderate physical activity during travel may also benefit bones, joints and muscles. Hu noted that activities associated with tourism can “enhance the body’s immune function and self-defense capabilities,” while supporting the body’s anti-wear-and-tear systems.
Despite the promising findings, researchers caution that the field remains in its early stages. Additional studies published in 2025 have described “travel therapy” as an emerging area of research requiring stronger methodologies and clearer long-term evidence.
Scientists also warned that travel does not automatically improve health. Poor travel conditions, infectious diseases, unsafe food or water, injuries and psychological stress can negatively affect the body and potentially increase entropy-related decline.
“Conversely, tourism can involve negative experiences that potentially lead to health problems, paralleling the process of promoting entropy increase,” Hu said, referencing the COVID-19 pandemic as an example of travel-related health risk.
Researchers say the findings should not be interpreted as suggesting travel itself prevents aging, but rather that positive, restorative travel experiences may serve as one component of broader healthy lifestyle patterns that support physical and mental well-being over time.
