“Sleep is the single most important health behaviour we have," says Professor Russell Foster, chair of Circadian Neuroscience and head of the Sleep and Circadian Neuroscience Institute at the University of Oxford.
"It affects everything from our day-to-day functioning to our long-term physical and mental health."
