What this trial studies

This study investigates the effects of guided forest therapy on individuals diagnosed with metabolic syndrome and cardiovascular risk factors. Participants will engage in weekly 90-minute sessions in the Düppeler Forest, where trained nature guides will lead exercises focused on nature perception, health connection, movement, and mindfulness. The study aims to assess the physical and mental health benefits of regular exposure to nature over a two-month period, with a control group waiting for therapy after the study concludes.

Who should consider this trial

Good fit: Ideal candidates are adults with metabolic syndrome as defined by specific waist circumference and risk factor criteria.

Not a fit: Patients with serious acute or chronic illnesses, mobility limitations, or serious mental health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the physical and mental well-being of patients with metabolic syndrome and cardiovascular risks.

How similar studies have performed: While the concept of forest therapy is gaining attention, this specific approach is relatively novel and has not been extensively tested in clinical settings.
