Explained examines why diets are often unsuccessful. It looks at the science that suggests that low carb, low fat, and body type diets as well as supplements and detoxification regimes simple do not work in helping most people lose weight. While the diet industry pushes us to avoid calories the food industry encourage us to eat more of them.
Thought of as a modern phenomenon, it actually started over 400 years ago with a spate of botched nose jobs. Since then, surgeons have been entranced with the idea that not only could they fix the body, but could even fix our sense of self-esteem. Presenter Michael Mosley undergoes both 16th-century bondage and 21st-century botox in his journey of discovery.
For hundreds of years, psychiatry has treated voices and hallucinations as an enemy - regarding them as 'insanity' or 'madness' and seeing them as something to be quashed and even frightened of. But today, new scientific and psychological insights into how the brain works are leading to a radical rethink on what such experiences are - and how they should be treated. Horizon follows three people living with voices, hallucinations and paranoia, to explore what causes this kind of phenomena. Providing a rare first-hand insight into these experiences, they reveal just what it is like to live with them day to day. They examine the impact of social, biological and environmental influences on conditions traditionally associated with insanity, such as schizophrenia and psychosis, and within the film they look at how new ways of understanding the brain are leading to a dramatic change in treatments and approaches, and examine whether targeting the root causes of psychosis can lead to recovery. Above all, they try to uncover why it happened to them - and whether it could happen to you.
For thousands of years, we’ve regarded sleep as nothing more than an annihilation of consciousness. But there is one compelling fact that has always stood in the way of that view. “Even the Greek philosophers wondered why we needed to sleep,” says neuroscientist, Dr. Kenneth Wright. “If sleep wasn’t important, it’s probably one of the most significant mistakes that evolution ever made.” Yet decades of intense research have failed to discover the key function of sleep. But now, thanks to revolutionary new technology, innovative animal research and extraordinary advances in genetics, all that’s about to change. Join Dr. Jennifer Gardy as she goes on an extraordinary odyssey from a city that never sleeps to an isolation chamber in the Colorado Rockies, from one of the most unique research centres in the world to the world of dreams. Her goal is simple: Discover why we sleep
The heart is the most symbolic organ of the human body. Throughout history it has been seen as the site of our emotions, the very centre of our being. But modern medicine has come to see the heart as just a pump; a brilliant pump, but nothing more. And we see ourselves as ruled by our heads and not our hearts. In this documentary, filmmaker David Malone asks whether we are right to take this view. He explores the heart's conflicting histories as an emotional symbol and a physical organ, and investigates what the latest science is learning about its structures, its capacities and its role. In the age-old battle of hearts and minds, will these new discoveries alter the balance and allow the heart to reclaim something of its traditional place at the centre of our humanity?
