The Science Of Sleep: How To Sleep Better

Four of Britain's best sleepers begin a major sleep deprivation experiment, in which they complete tests and have their brains analysed. Extreme snorer Yvonne, and Craig, who suffers from night terrors, are both treated at a sleep clinic.

Carla suffers from restless leg syndrome, while Peter has had chronic insomnia for 20 years. In the sleep deprivation experiment, a mini-casino is set up to see if the subjects gamble more and take more risks compared with when they are fully rested.
