Despite being looked down upon by traditional scientists, over the last years chronobiology has provided numerous new approaches to unexplained phenomena around human life – such as sicknesses. Light and rhythm shape our life. But not only ours: cabbage, for example, that is being stored in the dark contains significantly fewer nutrients than cabbage that is subjected to a circadian rhythm.

In our brains our "inner clocks" are directing our bodies' various biorhythms, which also occur in every single cell. Light is merely an outer timer for this clock. These clocks tick at their own individual speed and differently in each organ and each phase of our lives – when this is disregarded it is at the detriment of our well-being, performance and health.
