Скачать или смотреть How the Circadian Rhythm Works: The Science of Your Internal Body Clock

Have you ever wondered why your body often knows it’s time to wake up minutes before your alarm even goes off? It isn’t magic—it is a masterpiece of biological engineering known as your circadian system.

In this educational explainer, Sleep2DreamAnalytics pulls back the curtain on the "hidden metronome" that dictates when you feel tired and when your brain is firing on all cylinders. We explore the central pacemaker of the brain—the Suprachiasmatic Nucleus (SCN)—and zoom in to the molecular level to see the "genetic gears" that make your cells tick. You will learn how a simple dance between proteins creates a perfect 24-hour cycle and why light is the undisputed champion of keeping this system in sync with the planet.

In this video, you will learn:

• The Master Conductor: Why the SCN is perfectly positioned above your optic nerves to receive unfiltered information about light.

• Team Go vs. Team Stop: The elegant molecular feedback loop between proteins like Clock, Bmal1, Per, and Cry.

• Entrainment: How special cells in your retina, not used for vision, send high-priority "sun is up" messages to your brain.

• Peripheral Clocks: Why your liver, heart, gut, and muscles all have their own local clocks that follow the SCN’s lead.

• Circadian Desynchrony: The real-world consequences of jet lag, shift work, and late-night screen use on your long-term health.

Understanding this ancient internal timing system is like getting the user manual for your own body in our modern, 24/7 world.
