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.

The Horizon team have gathered together a team of scientists and doctors to investigate the incredible, natural material that is growing out of our heads - our hair. With access to the research laboratories of some of the world's leading hair care companies, including L'Oreal and ghd, the team explore the latest cutting-edge research and technology designed to push the boundaries of hair and hair care. Each one of us has a unique head of hair - an average of 150,000 individual hair strands growing approximately one centimetre every month. Over your lifetime, that is over 800 miles. The time and effort we put into styling, sculpting and maintaining this precious material has created a global hair care market worth a staggering 60 billion pounds. With such high stakes, it is inevitable that when developing hair-care products, science and business operate hand in hand. The team reveal how this industry science compares to the rigorous academic standards that they are used to. These investigations also reveal why we care so much about our hair, and whether or not it is worth splashing out on expensive shampoos. They uncover the magic ingredients found in conditioners and lay bare the secrets of the shiny, glossy hair seen in the adverts.

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.
