SAD season: There’s a name for depression that sets in for some in winter months

It’s like clockwork.

    Every holiday season, while millions of Americans get giddy about the holiday season and all its gifting and caroling and ho-ho-ho-ing, millions of others are experiencing a different set of emotions.

The days are shorter. The nights are longer. Winter sets in. Dropping temps keep us indoors. And for some, the idea of celebrating with loved ones doesn’t prompt the same warm, fuzzy feelings it does others (all family jokes aside).

There’s a name for the sort of general depression that sets in for some in the winter months. It’s called seasonal affective disorder. According to the Mayo Clinic, “Seasonal affective disorder (also called SAD) is a type of depression that occurs at the same time every year. If you’re like most people with seasonal affective disorder, your symptoms start in the fall and may continue into the winter months, sapping your energy and making you feel moody. Less often, seasonal affective disorder causes depression in the spring or early summer.”

This combined with the added stress that can come with the holidays, can be a bigger problem for people than you might think, especially in a culture where, while strides have been made in acceptance of mental illness, a stigma still exists.

Meg Stump, a psychologist with Mayo Clinic Health System in Mankato, said some of the answers are a matter of simple chemistry. When winter days bring less sunlight, the body produces less seratonin and more melatonin.

“Melatonin is a hormone that our brains produce during the hours of darkness,” the Mayo Clinic says. “It is involved with regulation of sleep, body temperature and release of hormones. As with any hormone, the amount produced is important. People with seasonal affective disorder produce too much melatonin. This disrupts our internal body clock leading to depressive symptoms.”
