Recovery Deficit
The recovery deficit is the gap between the resource depletion created by work demands and the replenishment achieved during off-hours. Sonnentag's recovery research identifies four mechanisms that close this gap — psychological detachment (mentally switching off from work), relaxation (low-activation positive states), mastery (engaging in non-work challenges), and control (having choice in how you spend leisure time). When all four are chronically absent, the deficit compounds across days, weeks, and months into clinical burnout.
How it sounds in your head
The inner script: 'I have time off but I still feel exhausted — maybe I'm just not a resilient person.' The research locates the mechanism more precisely: time off doesn't automatically produce recovery. If the off-hours are filled with work rumination, inbox checking, or low-control passive consumption, the recovery gap doesn't close — it narrows at best. The deficit isn't about character; it's about which specific activities activate each of the four recovery pathways.
