In almost all living organisms, including humans, physiology and behavior are regulated according to the day/night cycle.
This adaptation is made possible by an internal clock, called the circadian clock, which is present in each of our cells.
This clock is based on a network of genes that generate molecular oscillations with a 24-hour period, reset each day by light.
We now know that disruption of the circadian clock can have harmful consequences on health, that certain disorders appear preferentially at certain times, and that the efficacy of many drugs depends on their time of administration.
This talk will explain how our internal clock works, and why its integrity is so important to our health.
