The importance of sleep

How does sleep relate to your job, your income, or your socio-economic status? We look at the impact of a good, and bad night’s rest. We discuss the factors affecting sleep, including access to health care, where and how you live, and how that might influence other aspects of your life. Plus we look at the growing market in devices to ‘cure’ sleep problems. Producer and presenter: Elizabeth Hotson (Image: A man in bed in a deep sleep. Credit: Getty Images)
