I used to live in Portland, Oregon, which is one of the most beautiful cities in the world. That is, when the sun is shining. Unfortunately, the average rainfall in Portland is 37.5 inches a year and by the end of October until the end of May it can be very gray. I noticed that many of my patients would get the blues during these months.

It did not surprise me when Dr. Norman Rosenthal described the condition known as Seasonal Affective Disorder in 1987. It is a condition that most commonly starts in September when the light starts to change. It can continue until the light returns in the spring and summer. Those who suffer from SAD often complain of fatigue, loss of self-esteem, moodiness, and a craving for carbohydrates. Interestingly, SAD can occur for some people in the summer and seems to be related to heat.

Light therapy, exercise, and antidepressants can help alleviate these symptoms. If a light box is used, it should be done in the morning with a special light that mimics daylight outside. There is some suggestion that blue light may be preferable. Regardless, it is important to research the lights or ask your doctor for a suggestion.

If antidepressants work best for you, it is important to start them in late August before the light starts to change. Exercise is essential for general health and will help especially during the gray months. If you were able to get away and go somewhere sunny, that would be great.

SAD occurs in one in fifty people so it is very common. If you think that you may have seasonal effective disorder, talk to your doctor. He or she can help to give you a sunny disposition even when the sky is gray.
