I hate talking about depression because, well, it’s depressing. But if you’re one of those folks who gets S.A.D. in the winter, or you know someone who does, you may appreciate this post.

I’m talking about Seasonal Affective Disorder, i.e., folks who start getting more and more fatigued and listless for no apparent reason as the days get shorter and grayer.

If you’ve been told that you must have some deep-seated negative association with winter, forget that BS. Seasonal Affective Disorder is a biologically-based depression. It’s caused by a malfunction in a natural phenomenon that occurs in all of us. This natural phenomenon developed through evolution.

In cave-person times (tough to be politically correct when talking about that era), those folks whose metabolisms slowed down in the winter, so they burned fewer calories, were much more likely to survive until spring.They dragged their butts through the winters. But when spring came, they’d come bouncing out of their caves, full of renewed energy now that the sun was bright. Much to the annoyance of their skeletal cave-mates who just barely made it through the first hunt.

I have a mild case of S.A.D. When I lived in Maryland, I would get increasingly grumpy in the fall. I often wouldn’t realize just how depressed I became during the winter months, until spring came along and I started feeling sooo much better.

It was kind of like a low-grade, chronic case of the flu–one where you don’t realize just how sick you’ve been until you start to get better.

In the winter time, all of us (thanks to that evolutionary tendency inherited from our more wintertime-lethargic, springtime-energetic cave ancestors) have an increase in the release of the hormone, melatonin, from the pineal gland. This hormone regulates our sleep cycles and promotes deep sleep.This increased melatonin release makes us all a little bit less energetic in the winter.

For those with S.A.D., the melatonin levels increase too much, causing more severe fatigue and lethargy. S.A.D. can range from mild cases like mine to people who become severely depressed in the winter.

What can you do about it:

1.  The first thing to do (and this may be enough if you have a very mild case) is go outside as much as possible in the winter, especially on sunny days. Because it is not the cold that triggers S.A.D., it’s the lack of daylight. In my thirties, I started horseback-riding regularly year-round. My S.A.D. got a lot better. It went from a moderate to a mild case.

2.  Light therapy. There are light boxes, and other devices, that simulate sunlight. These are specifically designed to treat S.A.D., although they serve other purposes as well. More on light therapy below.

3.  Move to a southern clime, (or at least winter there, if you’re retired or filthy rich). My S.A.D. is one of the reasons–a major one, in fact–for our move to Florida when my husband and I retired.

More about light therapy boxes:

If you think you have S.A.D. these are a worthwhile purchase. They can change your life. But do your research first to find the best device for your needs. Check out this article from the Mayo Clinic about how to choose a light box. They range from $100 to $400, and unfortunately many insurance policies will not pay for them. (But they will pay for antidepressants that cost that much or more per month or for hospitalization when you’re suicidal. Go figure!)

Even if you have to pay out of pocket, it’s worth it to get your winters back! Someone asked me, shortly before our move south, why I was moving to Florida. I said, “Because I’m tired of wishing away almost half of my life.” I would start dreading winter by mid-October and wouldn’t really come out of it until some time in April. At that time, light boxes were much more expensive, but looking back, I should have bought one anyway.

Life is too short to spend anymore of it than necessary depressed!

Does this resonate with you? Do you think you, or someone you know, may have S.A.D.?
