Seasonal affective disorder is much more than the "winter blues."

*Originally published on January 27, 2022:

If you've been feeling off, moody, or even depressed, you may be suffering from seasonal affective disorder (SAD).

SAD is a type of depression that's related to the seasons—symptoms may pop up in the fall and continue throughout the winter months, before resolving during the spring and summer seasons. January is typically a peak time of year when people face SAD, or seasonal depression.

The American Psychiatric Association says SAD goes beyond the "winter blues," with symptoms ranging from mild to severe. It can also affect everyday life.

Symptoms include feeling sad or depressed; loss of interest in activities you once found enjoyable; sleeping more but not feeling well-rested; difficulty thinking or making decisions; changes in appetite; and a feeling of worthlessness or guilt.

However, there is good news! Several treatments can help combat seasonal depression.

One of the simplest ways to treat SAD is to expose yourself to sunlight; go on a morning walk or set up your workspace near a sunny window. It's also important to have a consistent sleep schedule and to get regular exercise.

A treatment that doctors may recommend is purchasing a lightbox. Sounds a bit strange, but it works! A study conducted at Yale's Winter Depression Research Clinic found that 10,000 lux lightboxes are "an effective treatment for SAD."

It's important to note: please make sure you're taking the proper steps to keep your mood and motivation steady throughout the year, not just during the "winter blues."

If you're still experiencing symptoms of seasonal affective disorder, consult a medical professional.
