At Roskilde, you probably don’t sleep like you do at home. But what does sleep deprivation actually mean to us? And is it true that you can learn while sleeping? Sleep researcher Birgitte Kornum knows more about this stuff than most. Get an introduction to the science behind sleep when Bloom – a festival of nature and science – invites all festival guests to take part in an unbiased study of the sleep rhythms at Roskilde Festival’s campsite. Bring the noisy night owls from the neighbouring camp to live sleep research at FLOKKR and see if you can pass Birgitte Kornum’s fatigue test.
