As the days get shorter, you may notice that mornings become harder. You want more sleep, have less energy, and start turning down plans you would normally enjoy.

It can be tempting to dismiss this as something you simply have to endure until spring. But a recurring seasonal change in mood deserves attention—especially when it affects your relationships, work, or ability to enjoy life.

Look for a pattern

During an evaluation, I want to understand when your symptoms begin, how long they last, and whether they improve during another part of the year.

Do you remember feeling this way last winter? What about the winter before? Are you experiencing depression throughout the year with seasonal worsening, or distinct episodes?

Those details help us understand whether seasonal affective disorder, another mood condition, or something else may be contributing.

You do not need years of detailed records. Your recollection is a useful starting point.

There are treatment options beyond waiting for spring

Light therapy is an established treatment for winter-pattern seasonal affective disorder. Psychotherapy and antidepressant medication may also be appropriate. A form of cognitive behavioral therapy adapted for seasonal depression, called CBT-SAD, addresses seasonal thinking patterns and helps people remain engaged in meaningful activities.

The right approach depends on your symptoms, health history, previous treatment experiences, and preferences.

A light box is a medical treatment tool

If you are considering light therapy, ask your clinician about an appropriate device, timing, and duration. Treatment uses a purpose-built bright-light box that filters ultraviolet light; an ordinary desk lamp or tanning lamp is not a substitute.

Eye conditions and medications that increase light sensitivity may affect whether light therapy is appropriate. It also needs particular care in people with bipolar disorder because it can sometimes trigger mania.

I would rather help you make a thoughtful plan than have you guess based on a product listing.

Make room for the things winter tends to crowd out

Alongside treatment, I encourage people to think practically about their winter routine.

Which relationships do you want to maintain? What activities are realistic when it is cold or dark? Is there something you can schedule now that you would otherwise stop doing?

The goal is to build a routine that supports you during a predictable difficult season.

Plan ahead when possible

If you recognize a recurring pattern, talk with your clinician before symptoms become severe. Some people benefit from starting a treatment plan ahead of their usual seasonal decline, although prevention research remains limited.

You do not have to wait for the calendar to change before asking for help. A seasonal pattern gives us useful information—and an opportunity to prepare.
