Shattered (2003)

Shattered was a reality television programme shown on Channel 4 in the United Kingdom. It aired in 2004. Ten contestants were challenged with going without sleep for seven days while their actions were constantly monitored. Over the seven days the ten housemates had to endure daily performance testing and a variety of challenges. They were competing for a potential prize fund of £100,000 though, at any point, if a contestant closed their eyes for over ten seconds, then £1,000 was deducted from the prize fund.
