The internal clockwork governing your every movement and biological rhythm

How does your body know what time it is? - Marco A. Sotomayor · 5:09 · Video: TED-Ed · Watch at the source

In short: From the precise timing of a catch to the rhythm of your sleep cycle, your body relies on an intricate network of internal timekeepers. This video explores the biological mechanisms that allow humans to perceive and synchronize with time.

The human body utilizes an interconnected system of specialized timekeeping structures within the brain. These systems are responsible for essential functions ranging from large-scale behaviors, like sleep-wake cycles, to split-second physical reactions, such as intercepting a fast-moving object.

By understanding how these internal clocks function, we gain insight into how our biology coordinates complex actions and maintains our sense of temporal awareness.
