Have you heard the collective sigh?
Yes, the groundhog saw his shadow, which means more winter. And many parents notice that right about now, kids and teens just seem… off.

Winter can quietly affect children and teens. Shorter days, less sunlight, disrupted routines, and school stress can all influence mood, energy, and behavior, even in kids who usually do well.

Often, parents notice changes before children know how to explain them.

Why Winter Affects Children’s and Teens’ Mood

During winter months, reduced sunlight can disrupt circadian rhythms and affect brain chemicals involved in mood and sleep. In kids and teens, this may show up as behavior changes rather than sadness.

This does not automatically mean something is wrong. It does mean it’s worth paying attention.

Common Signs of Winter Mood Changes in Kids and Teens

Parents may notice:

• Sleeping more or struggling to wake up
• Less interest in activities they usually enjoy
• Increased irritability, withdrawal, or tearfulness
• Complaints of fatigue, headaches, or stomach aches
• More difficulty with focus, motivation, or schoolwork

These patterns are common in winter. For some children and teens, they are part of Seasonal Affective Disorder (SAD), a form of depression linked to reduced light exposure.

SAD can affect children and adolescents, not just adults.

What Seasonal Affective Disorder Is (and Isn’t)

Seasonal Affective Disorder is associated with changes in light exposure that affect sleep cycles, melatonin, and serotonin.

It does not mean:

• Your child is weak
• You missed something as a parent
• Medication is automatically needed

Many children improve with early, gentle, evidence-based support.

Evidence Based Supports Providers May Recommend

Morning light exposure
Daily exposure to natural daylight or a medical-grade light box in the morning can help regulate sleep and improve mood. Light therapy is often one of the first strategies discussed.

Talk therapy
Child- and teen-focused therapy, including cognitive behavioral approaches, helps build coping skills and emotional awareness in developmentally appropriate ways.

Vitamin D Screening

Vitamin D deficiency is more common during winter months, particularly in northern climates with limited sunlight. Low levels have been associated with fatigue and low mood in some children and teens. A healthcare provider can help determine whether screening is appropriate based on symptoms, medical history, and risk factors, and discuss next steps if a deficiency is identified.

Medication (When Appropriate)

Antidepressant medications are not typically a first step for children with seasonal mood changes. In some cases where symptoms are moderate to severe and significantly affect daily functioning, a healthcare provider may discuss medication as a possible option, usually as part of a comprehensive treatment plan that includes therapy and close follow-up. Decisions about medication should always be individualized and made in collaboration with a qualified medical provider.

When Parents Should Reach Out for Help

Consider seeking guidance if:

• Symptoms last more than two weeks
• Changes are worsening
• School, sleep, or daily functioning is affected
• Your instincts tell you something isn’t right

Early conversations often prevent bigger struggles later.

If your child needs urgent emotional support:

• Call or text 988, the Crisis Lifeline (available 24/7)

Pro Tip for Parents

Winter mood changes in kids and teens often show up as behavior, not sadness.
Irritability, shutdowns, school resistance, or physical complaints are common signals.

Frequently Asked Questions

Is Seasonal Affective Disorder common in children and teens?

Yes. While often discussed in adults, SAD can affect children and adolescents. Symptoms may look different and often appear as behavior or school changes.

How long do winter mood changes usually last?

Mild changes may improve as routines stabilize or daylight increases. Symptoms lasting more than two weeks or affecting daily life should be discussed with a healthcare provider.

Does my child need medication for winter depression?

Most children do not need medication as a first step. Light exposure, therapy, routine support, and addressing vitamin deficiencies are commonly tried first.

Can too much screen time make winter mood worse?

Excessive screen time, especially late at night, can disrupt sleep and worsen mood regulation. Balanced limits and consistent routines are helpful.

When should I worry about safety?

If your child expresses hopelessness, talks about harming themselves, or seems unsafe, seek immediate help, or calling 911. You can call or text 988 at any time for guidance.
