The Science of Sleep: How to Sleep Better

The British Sleep Council says that 70 per cent of people in the UK do no get enough sleep. Gaby Roslin and Amir Khan present the first of two programmes in which they aim to put things right, applying the latest science to some of Britain's worst sleepers. They include a sleep deprivation experiment, as well as help for an extreme snorer and a man who suffers from night terrors.

Amir Khan and Gaby Roslin look at the cases of a woman who has restless leg syndrome, and a man who has had chronic insomnia for 20 years. Elsewhere, the sleep deprivation experiment continues, setting up a mini casino to test for risky behaviour, pain resistance and emotional control. Finally, as the subjects reach the final hours of the challenge, the experiment begins to take its toll as the participants' emotions go into overdrive, with one threatening to quit altogether. Last in series.
