'SAD sufferers worldwide owe Dr. Rosenthal a huge debt of gratitude, not only for pioneering SAD treatments, but also for writing and regularly updating this key book. The fourth edition is bang up to date, with many changes from previous editions, and remains fresh and interesting to read.' - Jennifer Eastwood, Honorary Life President, UK SAD Association 'Dr. Rosenthal was among the tight team of clinical researchers who first discovered SAD in the 1980s, and he has led the field ever since. Readers of the fourth edition will find a treasure trove of fascinating scientific information combined with invaluable practical guidance for overcoming this common, much-misunderstood problem.' - Chris Thompson, Priory Hospitals Group, UK 'From the definitive expert on SAD, Winter Blues remains the go-to, authoritative resource. If you have suffered with symptoms for years, read this book - your life can be less of a seasonal roller coaster.

In a warm, accessible style that is a pleasure to read, Dr. Rosenthal arms you with the information and tools you need to feel better across the seasons.' - Kelly J. Rohan, author of Coping with the Seasons 'A highly enjoyable book on SAD, written by the clinical scientist who has probably done the greatest amount of work on it.' - Journal of Clinical Psychiatry 'Probably the best book on SAD available for the lay person. Little sections on the history of seasonal time and how to decide whether to take medication or how to choose a therapist show much down-to-earth wisdom.' - Doody's Reviews 'This book has helped me to recognize my own seasonality, and its practical advice has offered me hope for a happier, more productive future. It was exciting to gain such a better understanding of my own behavioral patterns.

I've already begun to incorporate Dr. Rosenthal's recommendations into my daily regimen.' - C.W.
