Shattered is a reality television programme shown on Channel 4 in the United Kingdom, aired in January 2004 and presented by Dermot O'Leary.
Ten contestants were challenged with going without sleep for seven days while their actions were monitored, undergoing daily performance testing and a variety of challenges. They were competing for a potential prize fund of £100,000, with deductions made from the prize fund every time a contestant fell asleep.
Premise and challenges
Shattered was filmed in a specially constructed "laboratory" inside an abandoned shopping centre in Wapping.' The ten participants selected for the show were aged between 19 and 33, with one eliminated each night until the "sleep-off". They were initially kept awake for 36 hours, with a two-hour nap permitted before the live first episode.
You Snooze You Lose
Every day a contestant was chosen by their peers to endure an hour-long "You Snooze You Lose" challenge, in which the chosen contestant was tasked with remaining awake through an experience intended to encourage them to fall asleep. These challenges included cuddling teddy bears, listening to a bedtime story in an overheated room, and watching paint dry while seated in a comfortable chair. However, adverse effects of the sleep deprivation were evident in some contestants. For example, Chris reported major hallucinations and believed himself to be the Prime Minister of Australia, and Lucy left the show after consulting with the show's psychologists.
