The author discovers that winter makes his depression worse and that there’s a purely scientific explanation — and solution.
My therapist and I recently agreed that my Prozac intake should go up a bit for the duration of the winter.
I’m doing well for the most part, but there’s a three-hour window of each day — usually late afternoon — where my mood slides straight into the crapper.
The reason is simple: People who suffer from chemical imbalances in the brain are directly impacted by daylight levels. When the weather is dismal, cold, rainy and the days are shorter, a lot of folks with mental illness find themselves more depressed and moody. Give us a long stretch of dry, sunny weather and days where it gets light at 4:30 a.m. and stays that way past 8 p.m. and we tend to be happier people.
There are lessons to be had in the history books:
– Abraham Lincoln, a man who suffered from deep depression for most of his adult life, went from blue to downright suicidal a few times in the 1840s during long stretches of chilly, rainy weather. [See Why "Lincoln's Melancholy" is a Must-Read.]
– Ronald Reagan, a sunny personality by most accounts, was a man of Sunny California. Once, upon noticing that his appointments secretary hadn’t worked time in his schedule for trips to his ranch atop the sun-soaked mountains of Southern California — and after the secretary explained that there was a growing public perception that he was spending too much time away from Washington — Reagan handed him back the schedule and ordered that ranch time be worked in. The more trips to the ranch, he explained, the longer he’ll live.
The WebMD site has excellent information on winter depression. Here’s an excerpt:
If your mood gets worse as the weather gets chillier and the days get shorter, you may have “winter depression.” Here, questions to ask your doctor if winter is the saddest season for you.
Why do I seem to get so gloomy each winter, or sometimes beginning in the fall?
You may have what’s called seasonal affective disorder, or SAD. The condition is marked by the onset of depression during the late fall and early winter months, when less natural sunlight is available. It’s thought to occur when daily body rhythms become out-of-sync because of the reduced sunlight.
Some people have depression year round that gets worse in the winter; others have SAD alone, struggling with low moods only in the cooler, darker months. (In a much smaller group of people, the depression occurs in the summer months.)
SAD affects up to 3% of the U.S. population, or about 9 million people, some experts say, and countless others have milder forms of the winter doldrums.
So this worsening of mood in the fall and winter is not just my imagination?
Not at all. This “winter depression” was first identified by a team of researchers at the National Institute of Mental Health in 1984. They found this tendency to have seasonal mood and behavior changes occurs in different degrees, sometimes with mild changes and other times severe mood shifts.
Symptoms can include:
- Sleeping too much
- Experiencing fatigue in the daytime
- Gaining weight
- Having decreased interest in social activities and sex
SAD is more common for residents in northern latitudes. It’s less likely in Florida, for instance, than in New Hampshire. Women are more likely than men to suffer, perhaps because of hormonal factors. In women, SAD becomes less common after menopause.
Here’s where the Prozac comes in for me:
