Early birds and night owls are born, not made. Sleep patterns are the most obvious manifestation of the highly individualized biological clocks we inherit, but these clocks also regulate bodily functions from digestion to hormone levels to cognition. By understanding and respecting our internal time, we can live better.

The natural world is full of rhythms. How do birds know when to return to their nesting grounds? What effect do the seasons have on our wellbeing, and how does the season in which we are born affect our subsequent life chances? How did humans get the idea that there were seasons 50,000 years ago? Seasons of Life explains why the seasons occur, the impact of seasonal change and how organisms have evolved to anticipate these changes. For although we mask the effects of seasonal changes by warming our homes, lighting our nights, preserving foods and storing water, we cannot hide from them.

An enlightened approach to insomnia, depressed mood, fatigue, and other sleep-related problems of everyday life, harnessing the power of light therapy to reset the natural clock. Sleep problems and depressed mood often go hand in hand, forming a frustrating cycle. Michael Terman, PhD, has devoted his career to studying the brain functions that feed these disorders. His discoveries in chronotherapy have been widely recognized as game-changers by the medical establishment, and his 2010 New York Times op-ed, "Sleeping (or Not) by the Wrong Clock," shot to number one on the paper's list of most-forwarded online articles. In Chronotherapy, Terman and McMahan reveal the heart of his findings, a powerful program that recalibrates our internal clocks—our exquisitely designed, natural sensitivity to the timing and brightness of light exposure, which are often decimated by the modern demands of a 24/7 lifestyle. Beginning with a questionnaire to pinpoint problem areas, Terman helps readers decipher when their natural internal night is. The treatment process can then start, incorporating the power of natural light and, when necessary, supplemental light therapy. His approach has brought relief to thousands of sleep sufferers, as well as those burdened by bipolar disorder, seasonal affective disorder, depression, sleep disorders due to around-the-clock work schedules, and other impediments to vibrant health. For the first time, his findings are now available for a general audience, sharing the essential elements of chronobiology in clear, authoritative, scientifically grounded chapters that are easy to apply to a variety of situations. Chronotherapy chapters include: PART ONE: TIME, SLEEP, AND RHYTHMS Chapter 1: External vs. Internal Time The clock on the wall measures twenty-four hours every day, but the clock in your brain runs a little different. How can you help them work together? Chapter 2: The Pressure to Sleep The longer you stay awake, the more pressure you feel to sleep. But what if your inner clock says it is not yet ready for sleep? Chapter 3: Owls, Larks, and Hummingbirds What kind of "bird" are you? And once you know, how can that help you figure out when best to get stuff done? PART TWO: TIME, LIGHT, AND THE BRAIN Chapter 4: Getting Light into the Brain How do your eyes pass signals to your inner clock, and what makes those signals so important? Chapter 5: Getting Light Wrong Seeing light and being in darkness are basic daily experiences. But what happens when they come at the wrong times, and why does that have such negative consequences for mood, alertness, and sleep? Chapter 6: Geography and Time East or west, south or north, how can where you live have such a huge impact on your mood and sleep? PART THREE: INTERVENTIONS Chapter 7: Healing Light How can light help you solve your sleep problems, have more energy, and feel more positive about life? Chapter 8: Nighttime Meds and Melatonin Do you rely on pills to get to sleep? They may not work, and may be bad for you. But a new approach based on the brain’s inner clock holds great promise. Chapter 9: Hospitalized with Depression When someone becomes so depressed they need to go to the hospital, what promise does chronotherapy offer for a quick turnaround and continued improvement? Chapter 10: Beyond Light: The Charge in the Air What is it about spending a day at the beach that gives you such a lift? And how can you use new technology to bring home feeling of wellbeing? PART FOUR: STAGES OF LIFE Chapter 11: The Promise of Pregnancy You are going to have a baby! How can chronotherapy help you through the next nine months? Chapter 12: Strategies for Babies and Children When your baby or child sleeps well and feels good, you feel better too. How can chronotherapy help you reach this goal? Chapter 13: The Challenges of Adolescence As a teen, why do you feel the need to stay up so late and sleep so late? What are the consequences? What simple steps can you take to put your life on a smoother course? Chapter 14: In Later Years Does getting older have to mean being tired, sleeping badly, and feeling down? How to reverse these trends by using light. PART FIVE: CHRONOTHERAPY IN YOUR LIFE Chapter 15: Coping with Shift Work What if your job puts you on duty when your inner clock says you should be asleep? How can chronotherapy help you stay awake, alert, and in a decent mood? Chapter 16: Racing the Clock, Racing the Sun How chronotherapy prepares you for a trip and helps you recover from jet lag as quickly as possible. Chapter 17: Chronobiology in the Home and Workplace How will the collaboration of chronobiologists and architects transform the places you live, work, and learn? Chapter 18: Dawn of a Circadian Science Why is mainstream medicine so slow to put the insights of chronotherapy into practice?

Knowledge is a big subject, says Stuart Firestein, but ignorance is a bigger one. And it is ignorance--not knowledge--that is the true engine of science. Most of us have a false impression of science as a surefire, deliberate, step-by-step method for finding things out and getting things done. In fact, says Firestein, more often than not, science is like looking for a black cat in a dark room, and there may not be a cat in the room. The process is more hit-or-miss than you might imagine, with much stumbling and groping after phantoms. But it is exactly this "not knowing," this puzzling over thorny questions or inexplicable data, that gets researchers into the lab early and keeps them there late, the thing that propels them, the very driving force of science. Firestein shows how scientists use ignorance to program their work, to identify what should be done, what the next steps are, and where they should concentrate their energies. And he includes a catalog of how scientists use ignorance, consciously or unconsciously--a remarkable range of approaches that includes looking for connections to other research, revisiting apparently settled questions, using small questions to get at big ones, and tackling a problem simply out of curiosity. The book concludes with four case histories--in cognitive psychology, theoretical physics, astronomy, and neuroscience--that provide a feel for the nuts and bolts of ignorance, the day-to-day battle that goes on in scientific laboratories and in scientific minds with questions that range from the quotidian to the profound. Turning the conventional idea about science on its head, Ignorance opens a new window on the true nature of research. It is a must-read for anyone curious about science.

A science book like no other, The Where, the Why, and the How turns loose 75 of today's hottest artists onto life's vast questions, from how we got here to where we are going. Inside these pages some of the biggest (and smallest) mysteries of the natural world are explained in essays by real working scientists, which are then illustrated by artists given free rein to be as literal or as imaginative as they like. The result is a celebration of the wonder that inspires every new discovery. Featuring work by such contemporary luminaries as Lisa Congdon, Jen Corace, Neil Farber, Susie Ghahremani, Jeremyville, and many more, this is a work of scientific and artistic exploration to pique the interest of both the intellectually and imaginatively curious.
