Insomnia may arise from a weakened or delayed circadian rhythm that keeps the brain in “day-mode” at night. Poor sleepers show flattened mental rhythms and struggle to shift into the dream-like state needed for healthy rest.Learning Outcomes:
- Understand how disrupted circadian rhythms influence mental alertness and sleep quality, affecting cognitive readiness in military settings.
- Recognise the link between hyperarousal, problem-solving thought patterns, and poor nighttime recovery.
- Apply practical rhythm-shaping habits—light exposure, routines, and mental quietening—to support resilience, discipline, and health.
