ABSTRACT
The prevention and treatment of disease informed by knowledge of circadian rhythms is called “chronotherapeutics.” In Chapter 5, and throughout this book, we saw that circadian rhythmicity affects numerous physiological and behavioral processes. Therefore, it is not surprising to nd out that the symptoms of chronic diseases-such as allergic rhinitis, angina, arthritis, asthma, epilepsy, hypertension, and ulcer disease-exhibit daily rhythmicity.1 Awareness of these rhythmic patterns is essential for proper diagnosis of the diseases, as had been suggested by Arthur Jores in the 1930s2 and Franz Halberg in the 1950s.3
