In 2004, Channel 4 unleashed Shattered, a reality-TV show that dared ten volunteers to stay awake for as long as they could, transforming an abandoned London shopping centre into a high-stakes sleep lab. Contestants faced relentless mental and physical trials—and paid a price far beyond lost sleep. Wikipedia explains the unsettling premise.
Set inside a converted Wapping mall, contestants lived under 24/7 surveillance. Every time someone nodded off, £1,000 was docked from the £100,000 prize fund. Medical staff monitored heart rates and cognitive tests, while producers rolled out a series of “You Snooze You Lose” challenges to provoke microsleeps:

In one notorious task, contestants cuddled teddy bears while lullabies played at full volume. In another, they had to navigate a pitch-black maze without the benefit of rest. As fatigue set in, hallucinations and emotional breakdowns became the show’s grim trademark.

Ultimately, 19-year-old police cadet Clare Southern outlasted everyone, triumphing after an astonishing 178 hours awake—nearly seven straight days. She walked away with £97,000, but admitted later the ordeal left her battling chronic insomnia and anxiety. The Guardian takes stock of the post-show toll.
Health authorities were swift to condemn Channel 4’s gamble. The British Association for Counselling and Psychotherapy labeled it “dangerous and unethical,” warning that even experienced volunteers can suffer irreversible brain damage when deprived of sleep for extended periods. BBC Health reports on the medical backlash.

Channel 4 defended its format, pointing out that contestants had full medical support and the ability to withdraw at any moment. Yet the UK communications regulator Ofcom logged 34 official complaints, prompting a heated debate over whether reality television had finally gone too far.
Two decades on, Shattered remains a cautionary tale: when the quest for ratings marriage with experimental brutality, human well-being is all too often the casualty.
