13 Symptoms of Seasonal
Affective Disorder (SAD)

Let me boil all of these symptoms of seasonal affective disorder down for you.

Remember before in my first article on seasonal depression, I said there were two types of these disorders?

The first type comes on in the fall and winter and is often called winter depression. Below is a baker’s dozen of the most recognized symptoms, and the ones most reported, by people who have this type. (I’ll cover the second type and its symptoms further on down in the article.)

Understand that you (or your loved one) don’t have to have every single one of these for your doctor or expert healthcare provider to diagnose you with winter SAD.

Symptoms of Seasonal
Affective Disorder Include:

  1. Mood changes including anxiety and a feeling of hopelessness

  2. Lack of energy, with daytime fatigue and sluggishness

  3. Problems dealing with people, including being hypersensitive about rejection

  4. Irritability, grouchiness

  5. A feeling of isolation and withdrawing from being around people. Wanting to hibernate

  6. Being uninterested in most activities that were fun and that you once enjoyed before the onset of the symptoms of seasonal affective disorder

  7. A change in appetite, especially carbohydrate cravings (foods like potato chips and cookies)

  8. Through the years, times you’ve been depressed with winter depression are far more often than major depressive episodes at any other time of the year

  9. Weight gain

  10. Week after week is nothing but gloomy days. Life seems rather bleak.

  11. Some people say their arms and legs feel heavy

  12. A person feels fuzzyheaded with difficulty concentrating. Some people describe their mental symptoms as “like living in a fog”

  13. Excessive sleeping

What causes these symptoms of
seasonal affective disorder?

Here’s the blunt answer: Researchers of SAD don’t really know. However, they have assembled a line up of the biggest suspects:

  • Reduced sunlight: In the fall and winter the days get shorter and the eyes are taking in less daylight. This in turn affects the brain and leads to depression. How?

  • Because of serotonin. Researchers say the loss of sunlight leads to a drop in serotonin levels because with less light, the brain isn’t producing enough serotonin. This chemical, a neurotransmitter in the brain, affects mood, energy, sleep, appetite, and concentration. It’s known for its calming effects. So if there’s less of it, signs of depression may set in. And by the way, eating carbohydrates boosts serotonin, which is why one of the symptoms of seasonal affective disorder is carbohydrate cravings.

  • Then there’s melatonin: This is a hormone that plays a major role in regulating sleep cycles. And during the fall and winter change of seasons, melatonin levels can get all screwed up. Not only that, a National Institute of Mental Health study (Proc Natl Acad Sci U S A. 2006 Apr 28) reported that “most Seasonal Affective Disorder (SAD) symptoms stem from daily body rhythms [circadian rhythms] that have gone out-of-sync with the sun.” Researchers found that “Taking melatonin at the correct time of day...more than doubled improvement in depression scores.”

  • And finally, there’s the role of genetics. It appears that SAD may be a disorder that some people inherit and that develops in various families.

What about the second type
of seasonal depression?

Spring and summer mood changes can bring on this second type of depression. Typical summer depression symptoms are:

  • Insomnia
  • Losing weight
  • Lousy appetite
  • Grumpy attitude
  • Stress
  • A boost in sex drive

More extreme cases of depression in the spring and summer, called reverse seasonal affective disorder, have the main symptoms of greatly elevated mood and hyperactive energy levels (a form of bipolar disorder).

So let’s say you have some or many of the above smorgasbord of symptoms of seasonal affective disorder.

What next?

Well, the first thing you need to do if you are depressed can be summed up in two words: Get help. Please. Do it. Talk to your doctor.

See, the fact is, you must have a proper diagnostic assessment from a trained SAD professional. Not only to be sure of what you have, but to get the proper seasonal affective disorder treatment.
