In the ordinary course of life the human body follows a path of gradual disorder that scientists describe through the principle of entropy. Entropy, a concept drawn from physics, measures the natural movement of systems from organised states towards chaos and decay. Applied to biology it explains the steady accumulation of cellular damage, the slowing of repair mechanisms and the progressive loss of physiological resilience that we recognise as ageing.
A recent interdisciplinary examination by Fangli Hu and other researchers at Edith Cowan University, published in the Journal of Travel Research and led by PhD candidate Fangli Hu, takes this physical law and places it firmly within the domain of tourism.
The paper, titled The Principle of Entropy Increase: A Novel View of How Tourism Influences Human Health, argues that carefully chosen travel can act as a practical means of keeping the body in a lower-entropy condition for longer.
The central claim is straightforward. Ageing cannot be reversed, yet the rate at which entropy rises within the organism can be moderated. Positive travel experiences introduce a set of stimuli that support physical repair, metabolic balance and emotional recovery.
When a person leaves familiar surroundings and enters an environment that demands mild adaptation, the body responds with increased circulation, heightened sensory processing and a temporary elevation of metabolic rate. These responses are not random; they constitute a form of active maintenance that counters the everyday wear that accumulates in sedentary, routine-bound existence.
Keep moving
Physical movement forms one of the most reliable pathways. Most journeys require walking through unfamiliar streets, climbing stairs in historic buildings, strolling along coastal paths or simply navigating stations and terminals. Such moderate exertion strengthens muscles and joints, improves cardiovascular function and stimulates the body’s own tissue-repair systems.
In contrast to the constrained motion of office or domestic life, travel distributes activity across larger muscle groups and for longer continuous periods. The result is a measurable contribution to musculoskeletal health that accumulates with each successive trip.
Equally important is the reduction of chronic stress. Daily obligations generate a background level of tension that keeps the immune system in a state of low-grade activation and elevates cortisol over months and years.
Removal from that setting allows the stress response to subside. Beaches, mountain trails, quiet museums or simply the rhythm of a different city provide sensory inputs that shift attention outward. Positive emotions follow, and with them a cascade of physiological benefits that include improved sleep architecture and more efficient immune regulation. The Edith Cowan University team notes that these effects help maintain the low-entropy state by limiting the molecular damage associated with prolonged stress.
The loneliness snag
Social contact supplies a further protective layer. Travel almost invariably places the individual among new people, whether fellow travellers, local residents or service staff. Conversation, shared meals and the small negotiations of daily movement reduce feelings of isolation.
Loneliness itself accelerates physiological decline; its opposite slows that process. When social engagement is combined with the cognitive demands of an unfamiliar place, the brain receives a dual stimulus that supports both emotional stability and mental agility.
The same novelty that benefits the body also rewires the mind. Habitual environments allow the brain to operate on autopilot, relying on established neural pathways that require little conscious effort. An unfamiliar city, landscape or cultural setting forces the formation of new synaptic connections.
Cognitive flexibility increases as the traveller interprets signs, calculates routes, deciphers menus and adapts to different social cues. This neural rewiring is not merely temporary. Studies of creative professionals have long observed that periods of travel frequently precede breakthroughs in problem solving, precisely because the brain has been obliged to abandon familiar patterns.
Boosting creativity
Creative incubation occurs during the quieter intervals of a journey. After the initial stimulus of arrival, the mind settles into a state of open receptivity. Ideas that had remained stuck under the pressure of routine work begin to rearrange themselves.
Artists, writers and designers have recorded this effect for generations; the Edith Cowan University framework now supplies a biological rationale. By lowering the cognitive load of everyday demands and simultaneously providing fresh sensory material, travel creates the conditions in which insight can emerge.
Short trips prove sufficient to generate these advantages. The research indicates that even a weekend away from home can interrupt the entropy-increasing patterns of ordinary life more effectively than remaining in place during a period of formal holiday.
The change of environment itself, rather than the duration, supplies the decisive stimulus. This finding carries practical implications for people whose work or family responsibilities limit the length of possible absences. A carefully planned two- or three-day excursion can still deliver measurable benefits to both physical resilience and creative capacity.
Jet lag drag
Not every journey produces the desired outcome. The same paper is careful to record the opposite case. Travel that involves severe stress, accident, illness or exposure to unsafe conditions raises bodily entropy. Disrupted sleep, contaminated food or water, interpersonal conflict or the sheer exhaustion of poorly organised itineraries can leave the traveller in a worse physiological state than before departure.
The distinction between restorative and depleting travel therefore becomes critical. Planning that prioritises moderate activity, adequate rest and manageable novelty maximises the low-entropy effect; the absence of such planning reverses it.
The theoretical model advanced by the Edith Cowan University researchers is conceptual rather than clinical. It does not rest on a large-scale trial with measured biomarkers of ageing. Instead it synthesises existing knowledge from physics, physiology and tourism studies into a coherent framework that invites further empirical testing.
That framework nevertheless offers a coherent explanation for observations long made by travellers themselves: that time spent in new places often returns them home feeling both physically lighter and mentally clearer.
Lifestyle factors
The argument aligns with broader evidence on lifestyle factors that influence the rate of biological ageing. Physical activity, social connection, stress reduction and cognitive challenge each appear independently in the gerontological literature as moderators of decline. Travel simply packages these factors into a single, self-reinforcing experience.
The novelty of place multiplies the effect of movement; the movement multiplies the effect of social contact; the social contact multiplies the effect of emotional uplift. The resulting synergy is difficult to replicate within the constraints of daily life.
For policy makers and employers the implications are practical. Encouraging staff to take genuine breaks that involve travel, rather than remaining available online from home, may yield returns in both health and creative output.
For individuals the message is equally direct. The decision to leave familiar surroundings for even a brief period constitutes an investment in the maintenance of the organism and the flexibility of the mind. The cost of that investment is measured not only in fares and accommodation but in the willingness to accept temporary disorientation in exchange for longer-term resilience.
Seasons to be cheerful
Seasonal timing further refines the benefit. Autumn journeys, for example, often combine milder temperatures with fewer crowds, allowing more comfortable physical exploration and quieter reflection. The visual and climatic shift of the season itself adds another layer of sensory novelty without the extremes of summer heat or winter cold.
Such considerations allow the traveller to calibrate the degree of challenge to personal capacity, thereby keeping the experience within the restorative range.
The creativity dividend extends beyond professional domains. Everyday problem solving, interpersonal understanding and the capacity to generate new personal goals all improve when the brain has practised adaptation in unfamiliar settings. A person who has negotiated a foreign transport system or decoded an unfamiliar cultural code returns with a wider repertoire of responses to domestic difficulties. The neural pathways forged abroad remain available for use at home.
Overstated model
Critics may object that the entropy model overstates the power of tourism relative to genetics, diet or medical care. The researchers do not claim otherwise. They present travel as one accessible, non-pharmacological influence among others. Its value lies in its availability to large numbers of people and in its simultaneous action on multiple bodily and mental systems. Where medical interventions target specific pathologies, travel addresses the general background rate of entropy increase.
Future research will need to quantify the effect with biomarkers of cellular ageing, longitudinal tracking of cognitive performance and controlled comparisons between travellers and non-travellers.
Until those data appear, the existing conceptual work supplies a rigorous rationale for treating restorative travel as a legitimate component of health maintenance. The physics of entropy, once confined to thermodynamics, now offers a precise language for describing why a change of place can slow the felt progress of time and reopen the channels of invention.
Start with ONE overnight
What to do? Begin with modest steps. A single overnight journey to a nearby town that requires walking exploration, conversation with strangers and the decoding of a new spatial layout already engages the mechanisms described.
Scaleupward to longer or more distant trips multiplies the same processes. The essential requirement remains the quality of the experience: moderate physical demand, manageable novelty, adequate recovery and the absence of overwhelming stress.
Fangli Hu’s study therefore reframes an ordinary human activity as a deliberate intervention in the biology of ageing and the psychology of creativity. By keeping the body closer to a state of order and by compelling the brain to form new connections, positive travel supplies a dual benefit that few other accessible practices can match. The evidence is theoretical, the logic is consistent, and the invitation is open to anyone prepared to leave the familiar for a measured interval of productive disorientation.
