SLEEP, FATIGUE + ENDURANCE PROTECTION

THROUGH" A HIGH-RISK TASK.

Pattern	What can fail	Protection strategy
Short sleep / sleep debt	Attention, working memory, retrieval, reaction time, mood regulation and error detection can deteriorate.	Protect adequate sleep opportunity across the week; reduce late-night low-yield work before high-stakes days.
Night / circadian mismatch	Alertness may fall even when total sleep seems adequate; night work can create predictable vulnerability windows.	Use planned sleep, light/activity timing, breaks and supervised fatigue-mitigation processes appropriate to the setting.
Extended wakefulness	Performance may feel "normal" subjectively while accuracy, vigilance and response speed decline.	Use an external stop rule: timing, repeated errors, supervisor concern or unsafe drowsiness can override subjective confidence.
High caffeine dependence	Caffeine may improve alertness temporarily but does not replace sleep and can impair later sleep when used poorly.	Use judiciously; avoid escalating caffeine as proof that more work is safe.
Late-block accuracy decay	Endurance failure can appear only after sustained testing/clinical work.	Track first-vs-last block performance; train pacing and recovery, not just content.

Unsafe post-shift travel Fatigue can extend beyond the clinical task to the commute. Use institutional safe-transport/sleep options where available; do not drive when too fatigued to do so safely.

THROUGH" A HIGH-RISK TASK. — C. FATIGUE-MITIGATION CONTROL LOOP

When	Action	Proof / stop rule
Before high-demand period	Bank recovery where possible; plan meals/hydration, commute, breaks, sleep opportunity and backup coverage.	No preventable logistics problem is waiting to compound fatigue.
During work/study	Use breaks, strategic movement, appropriate caffeine, task prioritization and external monitoring of performance when risk is high.	Accuracy and alertness remain adequate for the task; otherwise escalate.
After duty / long exam	Choose recovery and safe transport over compensatory study.	The learner is safe to travel and has a realistic sleep opportunity before the next high-demand block.
Repeated fatigue pattern	Review schedule design, workload, health factors and institutional supports; do not normalize chronic impairment.	A root cause is addressed rather than repeatedly patched.
