The study followed 63 people who were randomly assigned a nature walk or an urban walk. The nature walk took place in a forest in Berlin and the urban walk took place on a busy street in the city.<\/p>\n
Participants were instructed not to check their phones or stop in stores while on their walk. They were given a bagged lunch and a phone with a 30-minute timer that instructed them to turn around. <\/p>\n
Before the walk, participants filled out a questionnaire and then underwent an fMRI scan that measured two tasks.<\/p>\n
The first task measured brain activity during a \u201cfearful faces task,\u201d in which participants were shown 15 female and 15 male faces that either had a neutral or scared expression. The second task measured was brain activity during an \u201cMontreal Imaging Stress Task,\u201d which is designed to create a level of stress in participants. During the task, participants had a set amount of time to solve challenging arithmetic problems.<\/p>\n
After the walk, participants filled out another questionnaire and underwent another fMRI scan that measured the same tasks they conducted before their walk.<\/p>\n
The results showed that nature significantly improved people\u2019s stress levels.<\/strong><\/p>\n The study found that those who took part in the 60-minute nature walk experienced lower stress levels following their time outside.<\/p>\n \u201cThe results of our study show that after only [a] one-hour walk in nature, activity in brain regions involved in stress processing decreases,\u201d Sonja Sudimac, the lead author of the study, told Medical News Today<\/a>.<\/p>\n Particularly, the researchers found the brain\u2019s amygdala activity (which is responsible for our stress and fear response<\/a>) decreased in those who were in the nature walk group.<\/p>\n This decrease was not seen in people who completed the city walk. According to the study, urban environments can negatively impact one\u2019s mental health, leading to increased rates of anxiety, depression and mood disorders. (Just think about the stress that comes with frequently honking horns, running to catch a bus or dealing with long lines just to get some groceries.)<\/p>\n In fact, other studies show<\/a> that mental health can suffer in urban areas because of the crowded nature of cities and, in general, the increased amount of stressors throughout the environment.<\/p>\n It\u2019s worth noting that the study had a few limitations: All participants were from a similar background and the study could not control who participants saw on their walk. So, for example, if someone on a walk in the forest saw someone relaxing on their day off, it could have further decreased the stress response in the participant.<\/p>\n This study also only focused on the benefits of a one-hour-long nature walk \u2014 it\u2019s unclear if the same positive results would occur in a shorter amount of time. But, Sudimac told Medical News Today that there is evidence that levels of the stress hormone cortisol decrease after a 15-minute nature walk, which would make a version of this study that looked at shorter walks interesting.<\/p>\n Plus, outside of this study, there is extensive research on the positive effects of the outdoors<\/a>, so it\u2019s not hard to conclude that even a few minutes outside is better than nothing.<\/p>\n Beyond decreased stress, nature has other benefits. <\/strong><\/p>\n Dr. Tamanna Singh<\/a>, co-director of the sports cardiology center at Cleveland Clinic, previously told HuffPost<\/a> that walking in nature has additional mental health benefits, too.<\/p>\n \u201cMany of us just don\u2019t get enough of nature, and a walk is a fantastic way to focus on taking in air, walking on mother earth, listening to the leaves rustling, the birds chirping, essentially \u2018forest bathing,\u2019\u201d she said.<\/p>\n Forest bathing has a number of benefits, she pointed out: It can help improve mindfulness, can be meditative and can improve your breathing. <\/p>\n![\"A](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/07\/6320c972260000600003398a.jpeg\")
A one-hour walk in nature resulted in a decrease in stress response in study participants. <\/p>\n
