WAT Method

The Science behind WAT

The core elements of Walks And Talks — walking, nature exposure, guided conversation, mindfulness, and body–mind integration — have all been widely studied in clinical and academic research. WAT brings these evidence-based components together into one coherent, human experience.

“Regular physical activity provides significant physical and mental health benefits (WHO).“

Mental health experts increasingly highlight walking as one of the simplest and most effective ways to improve wellbeing, reduce stress and restore mental clarity. Psychiatrist Christophe André describes walking as a way to “reconnect with oneself and open oneself to the world,” while former CDC Director Thomas Frieden famously called walking “the closest thing we have to a wonder drug.” Across cultures and health systems, walking is increasingly recognized as a powerful, accessible tool for emotional balance, cognitive clarity, resilience and social connection.

Below is a selection of research supporting the main pillars of the method.

Walking / Physical Activity

Effect of nature prescriptions on cardiometabolic and mental health, and physical activity: a systematic review
Spending time in nature as part of a structured programme improves physical activity levels, mental wellbeing and several health indicators. The review suggests that “nature prescriptions” are a low-cost intervention with broad health benefits.

Effect of exercise for depression: systematic review and network meta-analysis of randomised controlled trials
One of the largest analyses ever conducted on the topic found that physical activity can significantly reduce symptoms of depression. In many cases, exercise produced effects comparable to established treatments, with walking and jogging among the effective interventions.

Group Activities

Cohesion in group therapy: a meta-analysis
