The Effects of Nature-Based Activity vs. Indoor Exercise on Cognition, Psychological, and Physiological Health

Participants in this group will walk at a comfortable pace for 30 minutes in an urban park, three times per week for four weeks. They will be guided to focus on their surroundings using a grounding exercise (e.g., noticing sights, sounds, and smells) and instructed not to use mobile phones or listen to music during the walk.

Participants in this group will sit quietly for 30 minutes in a designated spot within an urban park, three times per week for four weeks. They will engage in grounding exercises and draw aspects of the natural environment. Participants will be instructed not to use mobile phones or listen to music during the walk.

Participants will be asked to walk on a treadmill in an indoor room without windows for 30 minutes. The treadmill will be set to the speed that match the average pace in nature walk group (approximately 3 km/hr). The speed could be adjusted by the participant if needed, but kept within the range of 2.6 km/hr to 4.6 km/hr. Participants will be asked to not use their phones or listen to music.
