We live in a highly rhythmic environment where the day is a completely different environment from the night, so all life is set to a 24h rhythm, which is governed by a circadian clock within all our cells. Aarti Jagannath will discuss what this clock is, and how it maintains a rhythm, and also how the circadian clock picks up time cues from both the environment and our behaviours to align our internal time with the outside world. Find out what happens when the body clock receives confusing time cues, as it so often does during our 24/7 lifestyles, and what we can do to fix a clock that has gone awry.
