Recent research underscores the undeniable benefits of exercising outdoors. A groundbreaking study from the University of Copenhagen and the University of Verona reveals that exercising in nature not only elevates mood and reduces stress levels but also enhances recovery compared to workouts in urban environments or indoor gyms. This revelation could be a game-changer for fitness enthusiasts and those seeking mental well-being.
The Power of Nature: Better Mood and Recovery
Exercise, in general, is widely recognized for its health benefits. However, when the location of your workout shifts from the gym or city streets to a tranquil natural setting, the effects on both body and mind can be significantly amplified. The study, recently published in the Psychology of Sport and Exercise journal, found that participants who exercised in nature reported superior psychological and physiological outcomes compared to those who exercised indoors or in urban areas.
In this study, 25 young men were asked to engage in a brisk, one-hour walk at a pace of six kilometres per hour in three distinct environments: a natural setting (forest park), an urban area, and an indoor gym environment. After each walk, the participants were assessed on various metrics, including mood, stress levels, and physical strain.
The results were telling. Those who walked in nature experienced a noticeable reduction in stress and greater feelings of recovery. Additionally, their motivation to repeat the exercise was higher compared to those who exercised in urban or indoor settings. As Stefano De Dominicis, Associate Professor at the Department of Sport and Nutrition at the University of Copenhagen, and one of the lead researchers, noted, “People felt less stressed after exercising in nature, were more recovered, and were more motivated to do it again.”
A Mental Health Boost: Nature vs. City vs. Gym
The study also examined psychological effects, highlighting the stark contrast between nature and urban or indoor environments. Participants reported experiencing the most positive emotions—such as joy, satisfaction, and optimism—during their walk in nature. In contrast, feelings of boredom increased significantly after walking indoors, while they decreased in nature.
Calmness was another prominent outcome, with nature walking yielding the highest levels of serenity. Participants who exercised indoors or in urban areas experienced a decline in calmness after their walk, whereas those who walked in nature felt more relaxed.
While the study does not suggest that exercising in the city or gym is detrimental, it emphasizes that nature holds unique psychological benefits. “We’re not saying that training in the city or indoors is bad,” De Dominicis clarifies, “Just that in some cases, you can get a little more out of it by doing it in nature.”
A Faster Recovery: Reduced Stress and Heart Rate
Physiologically, the findings were equally compelling. Participants’ heart rates decreased more quickly after walking in nature than after walking in urban or indoor environments. The study also found that cortisol levels, a marker of stress, dropped more significantly following nature walks. This suggests that not only do participants feel less stressed, but their bodies also recover more efficiently after a nature-based workout.

The Evolutionary Connection: Why Nature Matters
So, why does nature appear to have such a profound impact on our well-being? According to De Dominicis, the answer may lie in our evolutionary history. Humans have evolved in natural environments for most of history, and only in the last few thousand years have we transitioned to living indoors. This deep-rooted connection to the natural world may explain why our bodies and minds respond so positively to outdoor exercise.
“We have evolved in nature throughout history and have only lived indoors for the past few thousand years,” says De Dominicis. “Therefore, it’s beneficial to stay in calm, natural surroundings.”
Though he acknowledges that exercising in urban or indoor settings can still be beneficial for mental health, De Dominicis emphasizes that the effects are stronger when one takes their workout outside. This is especially important for those who are feeling stressed or overwhelmed.
Nature as a Motivational Tool for New Exercisers
Interestingly, the study also suggests that nature-based exercise could be particularly beneficial for beginners. Those who engaged in outdoor walks were significantly more likely to repeat the activity, which could be crucial for individuals just starting their fitness journey. De Dominicis explains, “If you exercise outside in nature, it feels good in a different way, and it can motivate you even more to continue.”
For those looking to build a sustainable fitness routine, nature offers not just a physical workout but also an emotional one—making it an ideal setting for those seeking both mental clarity and physical well-being.
Study Overview:
- Research Design: Randomized crossover study with 25 young men
- Environments Studied: Natural environment (forest park), urban area (urban walking environment), indoor gym (laboratory with treadmill)
- Activity: One-hour walk at a moderate pace (6 km/h) in each environment
- Psychological Measurements: Stress, mood, happiness, intention to repeat exercise
- Physiological Measurements: Heart rate, heart rate variability (HRV), cortisol levels in saliva
In conclusion, whether you’re a seasoned fitness enthusiast or just starting out, taking your workout into nature offers a range of benefits that urban or indoor exercise simply cannot match. From reducing stress to improving recovery times, nature-based exercise is not only good for the body but also for the soul. So, next time you’re thinking about hitting the gym or treadmill, consider lacing up your shoes and heading to the nearest park or forest instead. Your mind and body will thank you.
