For regular people, this means that playing a sport or building something with your hands is the literal biological antidote to the 'bloat' of digital life.
From the abstract
<div> This paper proposes an integrative framework, grounded in a nutritional metabolism analogy, for the ongoing debate on the relationship between digital media and mental health. The core claim is that the primary predictor of psychopathology is not the absolute quantity of screen time but the balance (additive imbalance) between non-selective cognitive input and experiential processing, with the qualitative classification criterion being sensorimotor loop closure—the presence or absence of b
