Burnout as a Loss of Reversibility Across Biological Scales

Burnout is commonly framed as a psychological state or organisational failure, yet these accounts often fail to explain why recovery becomes progressively difficult over time. Here, we propose a unifying reframing: burnout reflects a gradual loss of reversibility across biological scales. We argue that chronic stress leads to a "reversibility bottleneck, " cascading from behavioural habituation and blunted dopaminergic effort signalling to receptor downregulation and, ultimately, structural constraints on receptor conformational ensembles. Drawing on recent advances in structural biology, including AlphaFold 3, we discuss how prolonged exposure to biased signalling may restrict the conformational landscape of key receptors (e.g., D2/D3), limiting adaptive recovery. By integrating computational psychiatry with structural intuition, this perspective highlights that preserving the biological capacity for reversibility is as critical as managing external load.
