A third of the population regularly struggle with our sleep, which rose to one in two during the pandemic - the highest it’s ever been. However, as more and more people seek help, an explosion in sleep science is enabling the study of sleep in ways not possible before. What’s more, recent breakthroughs are uncovering what’s happening in our brains and bodies while we’re asleep, getting us closer than ever to understanding the importance of sleep for our health. Michael Mosley has struggled with his sleep for years and wants to know if the latest insights can help him and the millions like him. He discovers why cutting our sleep short can be linked to a host of illnesses, including serious diseases like Alzheimer’s. Putting his own sleeping brain and body to the test, Michael signs up for two revealing experiments: wearing a new device that maps his sleep and allows scientists to see how it measures up to an ideal night, and taking part in a sleep deprivation experiment, where he is confronted by the fact that just one sleepless night impacts his cognitive performance. Revealing the very latest science breakthroughs and packed with personal anecdotes, this programme is a useful guide to anyone looking for tips and insights on how to get the benefits from learning how to sleep well.

Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?

Take a journey deep inside the intriguing world of non-verbal communication. As human beings, our bodies communicate our inner emotions and feelings in ways that can often be easily seen by others, but at other times, are barely visible. On every continent and in every ethnicity, expressions of emotions such as happiness, surprise, anger and fear are universally recognized. These expressions are hard-wired into our facial muscles for reasons that have everything to do with human evolution and survival of the species. To the trained observer, the way people move can be more revealing than the things people say. Body Language Decoded features interviews with some of the world’s leading experts in human communication.

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 the worst sleepers. They include a sleep deprivation experiment, as well as help for an extreme snorer and a man who suffers from night terrors. A woman who has restless leg syndrome, and a man who has had chronic insomnia for 20 years. 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.
