The Dark Months in Helsinki

Aino Virtanen was twenty-three when she moved from Chennai to Helsinki for her master's degree. September was beautiful. By November the sun rose late and set by mid-afternoon, and she walked to the university and back in near darkness. She began to sleep ten hours and still wake exhausted. She craved sweet food, skipped lectures and stopped replying to messages from home.

She told herself she was homesick and weak. Her flatmate Katja, who had grown up there, saw it differently. 'Every winter I feel it too,' she said. 'Lack of light changes my mood. Come outside at noon with me.' They began a daily short walk at midday, even in grey weather. Katja also showed her a bright light lamp, which a university nurse had suggested to students.

Aino still found some days heavy. After three weeks, the nurse listened to her story and referred her to the student health service, where she was assessed properly. She learned that the winter pattern was real, that it had a name, and that it could be treated with daylight, routine, sleep regulation, talking support and, if the doctor judged it necessary, other treatment.

By March, as the light returned, she felt like herself again. She also kept a note in her phone, a plan for the next autumn, so she would not have to meet the dark unprepared.

How to recognise it

Low mood, heavy tiredness and oversleeping that begin in the same season each year, usually the darker months.
Craving for sweet or starchy food, weight gain and loss of motivation.
Loss of interest in friends and activities that are normally enjoyable.
Mood tends to lift in brighter weather or when the season changes.
Symptoms lasting more than two weeks and affecting study, work or relationships.

What this story explains

Light entering the eyes affects body clocks and mood, so seasonal changes can bring Seasonal Affective Disorder, as the chapter's sight section notes. Seeking light, routine and professional help works better than blaming oneself.

Probable root causes

Reduced daylight disturbing the body clock and the brain chemicals that regulate sleep and mood.
Moving to a new country, new climate and being away from family support.
Less outdoor movement and less social contact in cold, dark weather.
Possible personal or family history of depression.

What to do

Go outdoors in daylight each day, ideally in the morning or at midday, even for fifteen minutes.
Keep fixed times for sleeping, waking and meals.
Stay in contact with friends and family, and plan social activities in advance.
Move your body daily; a walk, stretching or a class counts.
Speak to a doctor or student health service if low mood lasts more than two weeks, and ask about light therapy and other options.

Whom to consult

Family doctor or student health service if low mood lasts two weeks or more.
Psychiatrist or clinical psychologist if the low mood is severe or the pattern repeats each year.
Eye doctor if low light, glare or vision changes are part of the problem.
If you ever have thoughts of ending your life, contact the local emergency number or go to the nearest hospital straight away.

Do and don’t

Do	Don’t
Do get outside in natural light daily.	Don't treat it as simple laziness.
Do keep a regular sleep routine.	Don't stay indoors all day under the blanket.
Do plan ahead for the seasons that are hard for you.	Don't use alcohol to cope with the dark months.
Do tell one trusted person how you feel.	Don't buy equipment or supplements without advice.
Do use any light device only as advised by a professional.	Don't wait until you stop functioning before asking for help.

How to behave and communicate

Say it kindly: 'You seem to be struggling every winter. Let's work out what would help.'
Avoid 'just cheer up'; try 'That sounds really heavy. I am here.'
Invite rather than push: 'Come for a walk with me at noon?'
Listen without fixing, and ask what the worst part of the day is.
Check in regularly during the dark months, not just once.
