The science of circadian rhythms is an interdisciplinary treasure trove with findings we can apply to our own lives, and society. We hope you will enjoy learning about what we know, as well as thinking about what remains to be discovered.

Circadian Rhythms Across the Lifespan

How do circadian rhythms change across the lifecycle? Find out how a mother’s pattern of rest and activity helps the fetus develop a circadian rhythm, how the amount of sleep you need changes as you get older, and why it is important to think about circadian rhythms to improve the quality of life for elderly people in nursing homes.

Wrinkle in Time

Jet lag, shift work, and Daylight Saving Time all disturb people’s circadian rhythms. What kinds of problems do such wrinkles create? How can we minimize their effects in our personal lives? What changes in school hours, policies for long-distance trucking, and so on, would reduce accidents, medical emergencies (such as heart attacks), increase productivity, and improve the quality of life?

Circadian Rhythm Disorders

Most people know that disruptions in circadian rhythms can cause insomnia and other sleep disorders, as well as seasonal affective disorder (SAD). But did you know that circadian rhythms are closely related to bipolar disorder and nonseasonal depression? Or that other disorders, such as schizophrenia, are associated with irregularities in circadian rhythms?

The Biology of Our Inner Clock

What is the inner clock that manifests itself in people, the birds and the bees, and even plants? How can you tell how whether your natural circadian rhythm is longer, or shorter, than 24 hours? What can you do to help your baby develop a healthy circadian rhythm?

Tips and Applications

How can you use information from chronobiology and chronotherapeutics to simplify your private life, or improve society? How do architecture and design affect circadian rhythms? How can the science of the inner clock be used to inform public policy?

About the Discipline

What critical experiments, ideas, and figures shaped this interdisciplinary science? Will the increasing interest in natural, organic food and remedies translate into a demand for natural (vs pharmacological) solutions to reduce insomnia, help people stay awake, or treat depression and bipolar disorder?
