Sleep. Do we get enough? The latest developments in circadian biology research are uncovering the detrimental effects that a lack of sleep can have to our well-being. Sleepless is the result of a two year conversation between artist Ellie Land and scientist Professor Peter Oliver about the links now being discovered between sleep and mental health. Its rhythm is inspired by the circadian cycle and displays visual icons rooted in the science of sleep, whilst featuring the voices of a group of mental health service users who share their experience of disrupted sleep/wake patterns.
