Here are 7 quotes that sum up SAD.

“Most scientists believe that the primary cause of SAD is diminished sunlight that accompanies the shorter days in the winter. For many people, reduced light triggers changes that reverberate throughout their bodies and minds, causing their moods to darken.”
Laura L. Smith & Charles H. Elliott

“The way you experience SAD is unique to you. You may feel tired, depressed, or irritable. You may experience changes in appetite or aches and pains. You may have difficulty concentrating or trouble sleeping. Whatever your symptoms, SAD can greatly affect your quality of life, making it difficult to enjoy things the way you used to.”
— Kelly J. Rohan

“SAD is more serious than bad moods related to cold weather or cloudy days. People with SAD usually report overwhelming feelings of fatigue, seriously depressed moods, cravings for carbohydrates, and disturbed sleep. These symptoms tend to endure through the winter months and improve in the spring.”
– Laura L. Smith & Charles H. Elliott

“Decreased activity may come before or after depressed mood. When you are experiencing depressed mood with a SAD episode, you are less motivated to do things. You begin to be less active because you are feeling depressed.”
—Kelly J. Rohan

“The relationship between SAD and negative thinking is actually a two-way street. Yes, the more depressed you are, the more your thinking turns negative. And as your thinking becomes more negative, your depression deepens. However, there is good news here. Whichever way the cycle starts, you can improve your moods by changing the way you think.”
– Laura L. Smith & Charles H. Elliott

“A highly effective way of alleviating SAD involves using the mind to re-establish good moods, increase energy, and instill hope. Again, the mind, body, and environment interact. When depressed people figure out how to think in nondepressed ways, their brains show improvements in functioning.”
– Laura L. Smith & Charles H. Elliott
