It emphasizes the crucial role of three key health behaviors—diet, exercise, and social connections—in maintaining brain health and reducing the risk of cognitive decline. Various studies and examples highlight how physical activities, particularly those involving cognitive challenges and preferably in green spaces, can protect the brain, boost cognitive function, and improve mood.
