Sleep is not passive rest. It is an active immune coordination window.
Subcomponents of Sleep and Immune Function
Immune memory formation
During sleep, the immune system consolidates memory responses and coordinates repair signaling.
Circadian timing
Immune cells operate on schedules. Disrupted sleep timing confuses immune deployment and recovery.
Inflammation control
Chronic sleep deprivation is associated with elevated inflammatory markers and reduced resilience.
Consistency over perfection
A stable wake time often anchors rhythm more effectively than chasing ideal bedtimes.
Practical direction: Protect sleep timing, light exposure at night, and sleep environment quality.
