Your brain has almost no oxygen reserve

Unlike muscle, the brain stores almost no oxygen. Consciousness can fade within seconds if blood flow stops, which is why stroke and cardiac arrest are neurological emergencies.

Constant perfusion delivers oxygen and glucose; vessels and autoregulation keep supply matched to local demand when you think or move.

The mind runs on a just-in-time pipeline. Protecting that flow — sleep, blood pressure, movement — protects the organ that cannot wait.
