Disrupted Circadian Rhythm: Late-night work interferes with the body’s natural sleep-wake cycle, reducing sleep quality.

Reduced REM Sleep: Night deployments shorten deep REM phases, affecting memory, mood, and cognitive performance.

Increased Sleep Debt: Frequent disruptions cause cumulative sleep loss that impacts long-term health and productivity.

Hormonal Imbalance: Irregular sleep alters melatonin and cortisol levels, leading to fatigue and stress.

Lower Alertness Levels: Sleep deprivation reduces focus, reaction time, and decision-making ability.

Higher Burnout Risk: Continuous night shifts increase emotional exhaustion and mental fatigue.

Inconsistent Recovery Time: Poor sleep prevents proper physical and mental recovery between shifts.

Lifestyle Disruptions: Night deployments affect eating patterns, exercise routines, and social life.

Long-Term Health Risks: Chronic sleep disruption increases risks of heart disease, anxiety, and metabolic disorders.
