Around a third of our lives are spent asleep, yet much of what happens in the brain during the night remains a mystery. In this talk, sleep researcher Celia Kjærby guides the audience through the different stages of sleep and explains why they matter for memory, recovery and mental health.
The evening looks at what defines good sleep, which factors can disrupt it, and what research says about improving sleep in a busy everyday life. Light, stress, caffeine, exercise and screen time are all considered in terms of their effects on the brain at night. The talk also offers a glimpse into Celia's own research on the brain's natural wakefulness systems, which help shape the structure of sleep itself.
Celia Kjærby is a sleep researcher and associate professor at the Department of Neuroscience at the University of Copenhagen. Her work focuses on how sleep affects the brain and its role in memory, brain health and neurodegenerative diseases such as Alzheimer's. The event is part of the Vild med videnskab series, which explores recent scientific research and how it can be applied in everyday life.
