What is circadian rhythm?

Our circadian rhythm controls our 24 hour cycle or body clock, and regulates our sleep cycles.

Our body clock is contolled by the SCN (Suprachiasmatic Nucleas), which are a group of cells in the hypothalamus which respond to light and dark signals.

The rhythm can be disrupted by shift work, jet lag, or teenage hormonal change.
