24-Hour Timeline

Hormones

GH largest pulse (~1 h after sleep onset). Melatonin at peak concentration. Testosterone synthesis begins via pulsatile GnRH → LH release during slow-wave sleep.

Body & Physiology

Liver Phase I detoxification (CYP450 enzymes) most active. Glymphatic system clearing amyloid-β from brain at 10× daytime rate. Bone marrow hematopoiesis peaks. Deep NREM (N3) delta waves dominant.

Atlas Tip

Complete darkness is essential — even dim light (>5 lux) suppresses GH pulse amplitude by 50%. Use 369-Atlas Deep Sleep Hypnosis track. MWO at 7.83 Hz (Schumann) before bed primes delta wave entry.

Educational notice: This circadian atlas is based on research from Satchin Panda (circadian time-restricted eating), Matthew Walker (sleep architecture), and endocrine chronobiology literature. Individual variation exists based on chronotype (early bird vs night owl), age, menstrual cycle phase, and health status. All recommendations are educational — consult a healthcare professional for personalized medical advice.
