Which theory explains why nature can help reduce stress?

Stress Reduction Theory is the correct choice as it specifically addresses the mechanisms through which nature contributes to alleviating stress. This theory posits that exposure to natural environments promotes psychological restoration and reduces stress by allowing individuals to experience a decrease in both mental and physiological stress responses. It suggests that natural settings evoke a sense of calm and relaxation, thereby enhancing overall well-being.

The theory emphasizes the restorative qualities of nature, explaining that environments rich in natural elements can help individuals recover from stress-inducing stimuli commonly found in urban or artificial settings. This experience often leads to improved mood and reduced anxiety levels.

In contrast, other theories like Attention Restoration Theory focus primarily on cognitive processes and the ability of nature to help restore focus and attention but do not specifically center on the broader impacts of nature on stress reduction. Cognitive Restoration Theory might deal with how cognitive functions can be rehabilitated through interactions with nature, while Nature Exposure Theory broadly discusses the benefits of interacting with nature without pinpointing stress reduction specifically. Thus, Stress Reduction Theory stands out as the most relevant explanation for the relationship between nature and stress alleviation.
