Will Make You See the Light
No need for a long review here. This is a great book on seasonal affective disorder, also known as SAD. It's written in the typical "For Dummies" format: uses layman's terms, icons througout the book to alert you to key points, organized in an easy-to-follow manner (i.e. paragraphs/ideas broken up in the chapters for easier "digestion" of the info).

Also typical of the "Dummies" books is the completeness. You'll learn the symptoms of SAD, if you have it, and what you can do about it. Some treatments covered in the book include:

-light therapy
-cognitive therapy
-exercise
-how to get better sleep
-changing your diet
-medications

As you can see, the book covers a lot of ground and most will no doubt learn a lot- I know I did. For instance, I found out that, according to the book page 222, that exercise and light therapy work EQUALLY well in treating SAD (see Exercise Beats Depression for a more detailed program if that's your thing). Anyway, I say get it if you you want a good, general knowledge of SAD, and to find out what all your options are. Its a great resource!

Excellent book
While some may be put off by the "For Dummies" series title, I have found most to be excellent starting points. Seasonal Affective Disorder for Dummies by Laura Smith and Charles Elliot is where I would suggest you begin if you have questions or interest in Seasonal Affective Disorder (SAD). It references up to date research in a practical, readable manner. It is very well organized and written.

While there is a very good chapter on Light Therapy, what I appreciate most is that most of the book addresses other interventions. What is known to date, is that effective treatments for depression are effective treatments for SAD. Another thing I like is how the authors give examples of negative thoughts in various chapters, followed by healthier thinking. Many will see their own negative thoughts and then see how they can begin to change it to healthier thinking.

If SAD is an issue for you, I highly recommend Seasonal Affective Disorder for Dummies.

Good way to bone up on a real disease
Concise yet detailed account of symptoms (craving carbs at night!) and treatment modalities of SAD.Lots of drug-free approaches, don't worry.

Excellent introduction to SAD
This is a tremendously helpful book for anyone who is looking for relief from winter's short days.The authors describe how to identify the signs and symptoms of seasonal affective disorder and suggest treatment options, including drug and non-drug approaches as well as practical coping strategies.It's written in a reassuring style that's easy to read and understand.

Very informative book re SAD
Very informative book regarding SAD - A must read for anybody suffering from Winter Blues

Revised Classic
Winter Blues is THE classic book on Seasonal Affective Disorder (SAD).Rosenthal started his psychiatric career as a research fellow at the National Institute of Mental Health (NIMH) and was one of the original researchers.In this addition, he also references his own experiences with SAD and what has been helpful to himself.

While the main thrust is on Light Therapy (LT), he also gives full and balanced discussion to other researched interventions, i.e., medications, psychotherapy (especially Cognitive Behavioral Therapy - CBT), negative ions, exercise, vitamins, etc.I appreciate that Dr. Rosenthal is not afraid to give his own opinions to questions about LT, after giving what is known through research.

Overall, it is important to know that SAD is very treatable for most people, whether with LT and/or with other interventions.

Winter Blues is well written and practical, doing an excellent job in referencing scientific studies in understandable language.Recommended for anyone with concerns about possible SAD issues.

Excellent Book - clear, concise and comforting
Well written, clear, easy to read and comforting in that you realize many people suffer to varying degrees with this.So glad I read this book.

For Anyone Who gets "Blue" in the Dark Days of Winter
The Winter Blues is an excellent guide for anyone who is affected by the darker days of Winter...it is very encouraging for anyone w/this often misunderstood malady & those who care for someone, who suffers through it. It is great to read that it can so simply be improved or reversed & that their quality of life can be restored so easily.

this book changed my life
This book was SO, SO helpful to me. I could tell the author understands what I have gone through (or as another reviewer said, it was very validating). As a result of reading this book, I bought a good light box (I had been using a very bright lamp, but it did not put out nearly the amount of lumens as the box I now have) and started taking Welbutrin during the fall and winter months. These two things changed my life! I no longer dread winter (although I still don't like it, especially the foggy weather the place I live is prone to) and, more importantly, I no longer go through the weeks of severe emotional pain where I prayed God would let me die. The very worst thing winter does to me now is a few weeks of being more tired than usual and mild blue days now and then.
I think the two people who gave the one star reviews don't have SAD. It's something I think you have to have to understand, altough there is a section in this book for freinds and family to read that is very good. As a person who has suffered severely from SAD, I can say the book is very good and HELPFUL. ... Read more

excellent resource
Easy read with valuable information. Author writes like a novelist, I could not put the book down.

Excellent overview of Seasonal Affective Disorder
This book gives a comprehensive overview of Seasonal Affective Disorder, as well as milder versions like the "winter blues" which affect many people, some of whom don't realize it.The book is written primarily for the layperson, either those who think or know they have SAD or those who know someone who does.If you fall into one of those catagories, this book would be worth reading.

The book explains the research behind the discovery of SAD (Dr. Rosenthal was one of the researchers who defined the disorder)and explains the various means of treating the problem.The author also puts SAD into a historical and literary context.After reading it, those affected by SAD will not feel that they are alone in their tribulations.They are part of a large group, and one that can live relatively normal lives with treatment and a little advance planning.

The book also offers information on distinguishing SAD from depression or bipolarity, and points out that SAD can co-occur with other problems.

Worth a read
I found this book particularly useful to me in that I was not all that clear about what seasonal disorder was all about and the author is both convincing and authoritative about the problem.Although I do not experience seasonal disorder, someone very close does and I read it to find out what it was.At first, as I read the book, I wondered if this was not hype but as I continued on, I realized that the symptoms described are quite like the person.

I benefited from reading the book but found the last few sections or chapters not to keep my interest because they tended to wander off into related but non-important areas for me.

However, the book taken as a whole is a very valuable if you need information.So, if you are or know someone who may suffer this illness (and even the author makes it clear that it is a diagnosable illness) then you will gain comfort by taking the time to read it.

A PATIENT'S PERSPECTIVE
This book was interesting to me as someone who has been diagnosed with seasonal affect disorder (SAD).However, I feel that the same information is restated and shown over and over again through different cases, makingthe book long if individual cases are not what you are looking for. I feltthat the book was written in plain language, but was still geared towardspsychologists and doctors.It did answer some of my questions aboutdifferent types of light therapy and as someone who has lived inScandinavia, I found his study of people who live in northern latitudeswith regard to whether they are more immune to SAD particularlyinteresting.If you think you may have SAD, the book provides a test whichdoesn't tell you much, but would confirm the severity of your case bydistiguishing it from "Winter Blues" and SAD.I think allpsycologists/psychiatrists should have this book in their libraries andread about SAD so they can recognize it for what it is.If more peoplewould acknowlege the disorder it would make it a lot easier on those of uswho have it.And maybe the insurance company would get around toreimbursing me for my expensive light box instead of only wanting to payfor pills. ...

Product Description
Seasonal affective disorder (SAD) affects a significant number of individuals, with an even greater percentage of population suffering from a milder version of the "winter blues."Cognitive-behavioral therapy (CBT) has long been recognized as an effective treatment for depression and now there is evidence that CBT can also benefit those with SAD. The group program outlined in this therapist guide tailors CBT for depression to the special needs of the SAD population. It can be easily adapted for use in individual therapy, as well as be combined with light therapy.

This therapist guide details twelve sessions to be completed over a six-week period. It gives step-by-step instruction for session activities and discussion. SAD-specific examples, sample dialogues, and diagrams help illustrate the points to be covered.Participants are provided with psychoeducation to further their understanding and awareness of SAD. They learn techniques to reduce symptoms, such as pleasant activity scheduling and cognitive restructuring.By increasing the amount of pleasant activities and changing thoughts and beliefs to be more adaptive, participants reverse the downward spiral of inactivity, negative thoughts and beliefs, and depressed mood.Relapse prevention helps participants maintain their gains and prepare for future winter seasons.

With proven CBT techniques and a strong focus on SAD, this guide is a valuable addition to the clinician's toolbox. A chapter on group logistics and an appendix with fidelity checklists will assist clinicians in successfully implementing the program.Home practice is an important part of the program and the corresponding workbook includes forms for each session.

Positive Options for Seasonal Affective Disorder
SAD is a very important issue for many Americans. Positive Options for Seasonal Affective Disorder by Fiona Marshall and Peter Cheevers is very educational.
SAD is depression caused by lack of natural light. In this book it described the many different cases of SAD. This is usually seasonal. Most of the depression is caused during the winter when there is a lack of sunlight and it is very cold. Many people become very tired and start to get aches and pains. In severe cases the depression starts to affect the person's social life. It interferes with their activities. Some can even lose every aspect of the person's life.
This book is a very useful tool for someone who suspects themself to have SAD. It goes through many different types of the illness. It also gives a lot of things that can be done to help cure SAD. It also describes how light and climate is very important to this illness. Light is especially important to have in your house and at your work. Without enough lighting SAD could become much worse and cause extreme depression.
There are many different symptoms of SAD. There is extreme fatigue and increased desire to sleep. Increased appetite and extreme mood swings. Many people have thoughts of suicide. Others might gain a drinking problem, or a drug problem. The seasonal depression starts and ends at certain times of the year. This can be caused by holiday blues also. People can feel very alone and lonely causing extreme depression. This depression usually only lasts for sixty days. More often than not this is found more in women than men. It can be linked to PMS. Most cases appear in those in their twenties to forties. SAD can become a very serious issue.
The book Positive Options for Seasonal Affective Disorder is very helpful. It gives you all the information anyone would need to know about the illness. SAD can be treated and should be taken seriously.
