Winter isn't a "wonderland" for everyone. Every year, millions of us feel our energy levels ebb and spirits fall as the days grow shorter. The condition is called seasonal affective disorder (SAD), and it can cause depression, reduce your productivity, and make it harder to control your appetite. In this no-nonsense, up-to-date survival kit for weathering the winter blues, Dr. Norman Rosenthal explains what causes seasonal mood swings and what you can do about them. A self-test allows you to evaluate your own level of SAD and helps you determine an appropriate plan of action. The book covers an expanded variety of methods proven to help you feel better--including new developments in light therapy, antidepressant medications, and breakthrough self-help strategies. Convenient menus and easy recipes make sticking to a healthy winter diet more enjoyable, and a new section on the benefits of exercise motivates you to stay active even when it's gloomy outside. A step-by-step guide helps you organize your yearly schedule to anticipate seasonal changes, and a special chapter for family and friends teaches loved ones effective ways to show support. Like a ray of light on an otherwise cloudy day. Dr. Rosenthal's expertise, warmth, and enthusiasm will inspire you to reclaim the winter months and find ways to celebrate even the darkest days of the year.
