😴 Two-Process Sleep Model (2D)

Live 2D simulation of Borbély's Two-Process sleep model: homeostatic sleep pressure (Process S) building and decaying against the circadian oscillator (Process C), with caffeine and sleep-deprivation controls.

⚙ Under the hood

A live 2D simulation of Borbély's Two-Process sleep model. Watch homeostatic sleep pressure (Process S) rise while awake and decay while asleep, gated by a 24-hour circadian oscillator (Process C) that shifts the sleep and wake thresholds. Adjust time speed, toggle caffeine to blunt sleep-pressure buildup, or force an all-nighter to see rebound sleep.
