Sleep regularity

Consistent adequate sleep and treatment of persistent sleep disturbance

Sleep is ranked as an important modifier, but the evidence should be presented as association and risk context rather than a guaranteed marker-lowering intervention.

Marker interpretation

The meta-analysis found sleep disturbance associated with higher CRP and IL-6, while experimental sleep restriction did not show consistent CRP or IL-6 effects. That means the page should not promise a numeric biomarker drop from sleep hygiene alone.

Practical focus and cautions

  • Use at least 7 hours in 24 hours as an adult planning floor.
  • Stabilize wake time, bedtime, light exposure, caffeine timing, alcohol timing, and late meals.
  • Escalate persistent insomnia, heavy snoring, repeated awakenings, or daytime sleepiness for clinical evaluation.
  • Long sleep can be a marker of underlying illness rather than a cause.
  • Sleep apnea, depression, chronic pain, medications, and shift work can dominate the biomarker signal.
