Travel Therapy: How Vacations Improve Physical and Mental Health According to Medical Research
6 October, 2026 Share
A 2025 study published by researchers Gerard T. Flaherty, Robert Steffen, and Karin Leder in the scientific journal Journal of Travel Medicine analyzes the concept of “travel therapy.” The research demonstrates objectively how moving to new environments benefits cardiometabolic health, psychological well-being, and the reduction of daily stress.
What Is “Travel Therapy” and Why Does Science Support Traveling?
Throughout the centuries, traveling to different places has been closely linked to human well-being—from ancient thermal baths to the search for warmer climates. Today, formal medical literature consolidates the concept of “travel therapy” (or travel prescription) to analyze the biological, psychological, and social effects of changing one’s environment.
Temporarily stepping away from daily obligations stimulates cognitive flexibility, strengthens resilience, and fosters sociocultural empathy by connecting with different realities. At RIU Hotels & Resorts, we share how the experience of travel brings measurable value to bodily health and emotional balance.
How Does Tourism Influence Physical and Cardiometabolic Health?
The positive impact of a trip extends well beyond a feeling of rest; medical research confirms tangible physiological changes during vacations:
- Nutrition and Mediterranean Diet: Enjoying balanced gastronomy during vacations—such as the nutrient-dense Mediterranean diet—helps reduce cardiovascular risk factors compared to home routine diets.
- Climate, Altitude, and Joint Health: Exposure to warm and temperate climates relieves joint stiffness in individuals with rheumatic conditions. Additionally, research on moderate altitude (such as the Austrian Moderate Altitude Study) cited in the paper reveals significant improvements in glycemic control and cardioprotective HDL cholesterol levels.
- Air Quality and Lung Health: Traveling from urban environments with high pollution levels to holiday destinations with clean air offers a valuable preventive break for the respiratory system.
- Vascular Health and Relaxation: Engaging in relaxing activities, thermal baths, and wellness sessions at facilities such as Renova Spa spaces promotes vasodilation, which helps reduce blood pressure and arterial stiffness—a key indicator of vascular aging.
How Do Vacations Benefit Mental Health and Digital Detox?
In a society characterized by hyperconnectivity, traveling facilitates a digital detox, a crucial factor in lowering accumulated cortisol and anxiety levels.
Science has found that the positive impact begins even before boarding the plane. Functional magnetic resonance imaging (fMRI) studies cited by Flaherty et al. (2025) reveal that anticipating and planning a trip activates the brain’s medial prefrontal cortex, a region associated with emotional well-being and happiness.
Furthermore, travel acts as a natural sleep self-regulator: individuals suffering from sleep deprivation manage to stabilize their sleep patterns during a vacation stay.
The Power of Nature: “Forest Bathing” and Sea Breeze
Nature-based tourism is backed by solid scientific evidence. Practices such as shinrin-yoku (forest bathing), originating in Japan, allow the body to inhale phytoncides (volatile organic compounds emitted by plants and trees) that diminish stress responses and boost immune defenses. Destinations surrounded by tropical biodiversity, such as the lush vegetation near Hotel Riu Palace Mauritius in Mauritius, facilitate this type of restorative natural exposure.
Similarly, coastal and marine environments feature a high concentration of Negative Air Ions (NAIs), natural particles that clean airborne particulate matter and enhance feelings of vitality. Coastal destinations with broad stretches of dunes and ocean, such as Hotel Riu Palace Maspalomas in Gran Canaria or Hotel Riu Palace Santa Maria in Cape Verde, serve as geographic examples where direct sea breezes promote these beneficial atmospheric elements.
Summary Data Table: Travel Benefits According to Scientific Evidence
| Health Dimension | Key Mechanism or Factor | Proven Effect on the Traveler (Flaherty et al., 2025) |
|---|---|---|
| Mental Health | Digital detox and routine change | Reduction of stress markers and lasting mood enhancement. |
| Cardiovascular Health | Balanced nutrition and physical relaxation | Improved blood pressure and lower arterial stiffness. |
| Sleep Quality | Circadian rhythm reorganization | Self-regulating effect: optimizes rest in sleep-deprived individuals. |
| Natural Environments | Exposure to phytoncides and Negative Air Ions (NAIs) | Reduced anxiety and strengthened immune response. |
| Family Well-being | Shared experiences and cohabitation | Reinforcement of emotional bonds, communication, and mutual trust. |
What Is the Optimal Vacation Duration According to Science?
Researchers observe that the relationship between travel duration and its restorative effects follows an inverted U-shape curve: moderate-length stays generate the maximum biological and emotional benefits.
After returning home, improvements in mood, stress reduction, and sleep quality typically persist for 3 to 5 weeks, demonstrating that travel is a genuine investment in preventive health.
