We know a good night's sleep is essential for a healthy brain and body. But sleep problems are sadly all too common. So why do so many of us struggle to sleep well? In 4 Weeks to Better Sleep, Dr Michael Mosley explains what happens when we sleep, what triggers common sleep problems and why standard advice rarely works.
