It may come as no surprise to learn that Britons are among the world’s worst sleepers. This series has assembled a team of experts, led by consultant neurologist and sleep physician Dr Guy Leschziner, who will monitor the patients who come to their sleep clinic.

This week, the patients are Izzy, who is still experiencing night terrors at the age of 20, Phil, a dad of two who has narcolepsy, Nancy, a student who sleepwalks, and Michael, who appears to have sleep paralysis.

After 36 hours’ observation, the team put together tailor-made plans for them – can they help the exhausted patients?
