This document discusses evidence for the occupational nature of humans and the relationship between occupation and health. It summarizes several studies that demonstrate benefits of occupation-based interventions compared to other activities. One study found that occupation-based activities led to quicker reaction times and smoother movements compared to rote exercise. Another study linked social and productive activities to increased survival in elderly adults. Additional research identified benefits of knitting for well-being, such as stress relief and socialization. The document advocates that occupational therapy practice should be both evidence-based and philosophically aligned with the occupational nature of humans.
