Written by a world leader in circadian rhythms, this book will change the conversation around sleeping and eating. Change your daily routine, transform your health. Circadian rhythms are biological processes or clocks that exist in each one of our cells. Programmed to turn genes on or off at different times of the day or night, they influence every aspect of our health from weight and energy levels through to resistance to disease and infection, and how well we sleep. Now, in The Circadian Code, this new science is revealed, showing that the timings of our day (when we eat, sleep, exercise, work) are more crucial than we ever thought before. And that, most importantly, if your daily schedule is out of sync with your circadian rhythms, you can fix it! Whether you are a shift worker, a frustrated dieter, someone suffering from sleep problems or chronic illness, whatever your health concern, The Circadian Code is the key to unlocking your health.
