How to Cope With the Winter Blues: 8 Ways to Keep Your Mood Up When Days Get Short

The clocks have changed or are about to. You leave for work in the dark and come home in the dark. You want to sleep more, eat more carbohydrates and see fewer people. Things you usually enjoy feel like effort. You wonder if this is just autumn, or something more.

For many people, mood dips as the days shorten. Knowing what is normal, what is not and what helps makes the season much easier.

Winter blues or seasonal affective disorder?

The winter blues

The winter blues are a common, milder shift: lower energy, feeling a bit flat, wanting to hibernate, craving comfort food and being less motivated. They tend to come and go, and you can usually still function and enjoy some things.

Seasonal affective disorder (SAD)

Seasonal affective disorder is a type of recurrent depression with a seasonal pattern, typically beginning in autumn or winter and easing in spring or summer. Norman Rosenthal and colleagues first described the syndrome in 1984. Symptoms can include:

• persistent low mood most of the day, nearly every day,
• loss of interest in activities,
• oversleeping, low energy and fatigue,
• increased appetite and cravings for carbohydrates, with weight gain,
• difficulty concentrating,
• feelings of worthlessness or hopelessness,
• withdrawing from people.

The key differences are severity and impact: SAD lasts for weeks and disrupts work, relationships and daily life. If symptoms last two weeks or more and interfere with functioning, it deserves professional attention. See why do I feel sad for no reason. A summer pattern of depression is less common but exists.

Why short days affect mood

Researchers think reduced daylight can disrupt the body clock (circadian rhythm), alter melatonin and serotonin signalling and shift sleep, which in turn affects mood. Not everyone is equally affected; risk is higher in people who live farther from the equator, have previously had depression and for some people with family history.

8 ways to cope with the winter blues

1. Get light early, every day

Morning daylight is the strongest signal for your body clock. Go outside within an hour of waking for 15 to 30 minutes, even when it’s overcast, which is still brighter than indoor light. Sit near windows at work. Take a lunchtime walk. See how to become a morning person.

2. Consider light therapy

Bright-light therapy, using a special light box (commonly 10,000 lux) for 20 to 30 minutes in the morning, has the best evidence among non-drug treatments for seasonal depression. Daniel Golden and colleagues’ meta-analysis found that light therapy had significant benefits for seasonal depression and also some benefit for non-seasonal depression. Talk to your doctor first, especially if you have eye conditions, bipolar disorder or take medication that increases light sensitivity.

3. Move your body

Walks, runs, classes, dancing or gentle yoga lift mood and help sleep. Combine with outdoor light for double benefit. See how to start exercising when you have no motivation and how to build a daily walking habit.

4. Keep a steady sleep schedule

Go to bed and wake at consistent times, even on weekends. Oversleeping can worsen grogginess and mood. Avoid screens late at night. See how to build an evening routine for better sleep.

5. Build a morning and daily routine

Structure helps when motivation is low. A simple routine of waking, light, breakfast, movement and one task gives your day a skeleton. See how to build a morning routine.

6. Stay connected

The urge to withdraw is strong, but isolation deepens low mood. Schedule regular contact: a weekly call, a coffee, a class or a group. Choose small, low-effort plans. See how to make friends as an adult.

7. Plan things to look forward to

Pleasant activities are a form of “behavioural activation,” a core tool in treating depression. Put at least one enjoyable thing in your calendar each week: a film night, a cosy dinner, a day trip, a hobby session. Make winter something with its own rituals: candles, soups, books and winter walks.

8. Eat and drink with care

Cravings for carbohydrates are common. Include protein, vegetables and fibre and keep meals regular. Limit alcohol, which can worsen mood and sleep. Ask your doctor about vitamin D if you rarely get sun, because levels can be low in winter, but do not self-prescribe high doses.

When the dip is more than the blues

Talk to a doctor or therapist if:

• low mood lasts two weeks or more,
• you lose interest in nearly everything,
• you can’t work, study or look after yourself,
• you feel hopeless, worthless or very anxious,
• you use alcohol or other substances to cope,
• it keeps happening every year,
• you have thoughts of harming yourself.

SAD is treatable. Options include light therapy, cognitive behavioural therapy adapted for seasonal depression, antidepressant medication and combinations. Starting treatment before symptoms begin is sometimes recommended for people with a clear annual pattern. The National Institute of Mental Health has information about depression. If you are in crisis, contact your local emergency number or, in the United States, call or text 988. See our disclaimer.

A worked example

Mei feels flat and sleepy every November.

1. Light: she walks for 20 minutes outside before work and sits by the window at her desk.
2. Light box: after talking to her doctor, she uses a 10,000-lux lamp for 20 minutes with breakfast.
3. Movement: a Tuesday and Thursday evening class.
4. Sleep: she sets a fixed bedtime and wake time.
5. Routine: breakfast, light, one important task before noon.
6. Connection: a standing Friday dinner with friends.
7. Looking forward: she books a weekend trip in January.
8. Food: she keeps regular meals and cuts back on late-night wine.

Her mood still dips a little, but she keeps functioning and feels more in control.

Common mistakes

• Waiting for spring. Start now.
• Isolating. Keep small contacts.
• Oversleeping and skipping daylight. Get up and go out.
• Self-medicating with alcohol. It worsens mood.
• Dismissing persistent symptoms. Get help.
• Overdoing supplements. Talk to a doctor.

Frequently asked questions

What is the difference between the winter blues and SAD?

The winter blues are mild and manageable; SAD is a form of depression with a seasonal pattern that disrupts daily life.

Does light therapy work?

Clinical trials show it is effective for many people with seasonal depression. Check with a doctor first.

When does SAD usually start?

Often in autumn or early winter and improves in spring, though patterns vary.

Can vitamin D help?

Levels can fall in winter, and a doctor can check them, but vitamin D is not a proven stand-alone treatment for SAD.

Why do I crave carbs in winter?

Changes in mood, energy and appetite regulation can increase cravings; regular meals and protein can help.

When should I see a doctor?

If low mood lasts two weeks or more, disrupts your life or includes hopelessness or thoughts of self-harm.

The bottom line

Shorter days can lower mood, energy and motivation. Get morning light, consider light therapy, move, keep your sleep and routine steady, stay connected, plan pleasures and eat with care. If the dip is deep or lasts, seek help: seasonal depression is treatable.
