Sleep, or lack of it, affects everything we do. Whether it's our mood, appetite or even reaction times, getting the requisite amount of shut-eye is the most important thing we can do for our bodies.
But even though we spend a third of our lives sleeping, many of us are pretty terrible at it. Nightly issues include not dropping off, dropping off and then waking up, or even dropping off too fast, which can also signify exhaustion which is not healthy.
Dr Michael Mosley has struggled with his sleep for most of his adult life, and at the age of 64, he decided to investigate. Teaming up with the Sleep & Circadian Neuroscience Institute at the University of Oxford, he posed the UK Sleep Census for the documentary How To Sleep Well with Dr Michael Mosley (BBC Two, Thursday, 9pm).
