How to Beat the Autumn Blues When It Gets Dark at Five

The clocks go back, and the following Monday you walk out of work into what looks like midnight. It is quarter past five. You had plans for the evening – the gym, a call with a friend, that form you keep meaning to fill in – and every one of them now feels like something a different, more energetic person signed you up for. You go home, eat something beige, and scroll until bedtime.

A week of this is nothing. Two months of it is how autumn quietly swallows a quarter of your year. The good news is that the autumn blues have fairly ordinary causes, and most of them respond to fairly ordinary fixes. Here is what to change, in what order, and how to tell when the problem is bigger than the season.

What the autumn blues actually are

"Autumn blues" is an everyday phrase, and no doctor will write it on a form. People use it for a familiar cluster: waking up is harder, the afternoon slump is deeper, you crave bread and sugar, you cancel plans more easily, and things you normally enjoy feel a bit flat.

Several small changes pile up at once.

• Less light. Your body clock sets itself by light, morning light above all. Wake in the dark, commute in the dark, sit under office strip lights all day, and the clock has nothing to lock onto.
• Confused sleep. Darkness tells your body to produce melatonin, the hormone that prepares you for sleep. When darkness arrives at five, you feel drowsy early and still fall asleep late.
• Less movement. In summer you walk without deciding to. In autumn the route shrinks to door, car or train, desk, and back.
• Fewer people. Nobody cancels anything. The casual plans – a drink outside, a walk after dinner – simply stop being suggested.

None of these is dramatic on its own. Together they produce the feeling that everything costs twice the effort. That also points to the fix: put back some of the light, movement and company, and things get noticeably easier.

Autumn blues or seasonal affective disorder

This section comes before the advice on purpose. Walks and routines help with an ordinary seasonal dip. With depression they can support treatment, but they do not replace it.

There is a clinical version of the seasonal slump: seasonal affective disorder, usually shortened to SAD. It was first described in 1984 by the psychiatrist Norman Rosenthal and his colleagues. It is a real diagnosis, made by a doctor and treated under a doctor's care.

Start with light

The thing that changed in autumn is the amount of light, so that is the first thing to put back.

Get outside before mid-afternoon. Even an overcast sky at noon is far brighter than any room in your home or office. Twenty to thirty minutes gives your body a clear signal that it is daytime. Easy ways to fit it in: get off the bus a stop early, walk to a lunch place that is ten minutes away instead of two, take your first call of the day on foot with headphones.

Move your desk to the window. If you work at the back of the room, shift for the dark months. At home that takes ten minutes. At the office it takes one conversation.

Open the curtains the moment you get up. Switch on every overhead light while you get ready. A dim morning under one kitchen bulb stretches the night by another hour.

Dim things in the evening. An hour or so before bed, turn off the bright overhead lights and switch to warm lamps. In summer the sun draws the line between "active" and "winding down". In autumn you have to draw it yourself.

Protect your sleep window

A classic autumn trap goes like this. You nod off on the sofa at seven, wake at nine feeling worse, and then lie awake until two. The alarm goes off in the dark, and the loop starts again.

What breaks it:

1. One wake-up time, seven days a week. Wake-up time, not bedtime. You cannot fall asleep on command, but you can get up on command. After a few days, sleepiness starts arriving at the right hour by itself.
2. No naps after five. If you truly need one, twenty minutes at lunchtime does far less damage than ninety minutes at dusk.
3. Weekends within an hour. Sleeping until noon on Saturday is the same as flying a few time zones west and back by Monday. An hour's difference from weekdays is a sensible limit.
4. A quiet last hour. A bright screen close to your face and work email both push sleep later. You do not need candles and a paperback. You do need to finish whatever winds you up before that last hour starts.

Move in daylight, even badly

The most common autumn mistake with exercise is buying a gym membership and promising yourself four sessions a week. When walking to the shop feels like an effort, that plan lasts until the first missed session and then adds guilt to the gloom.

A better bar for the dark months: move every day, a little. A twenty-minute walk counts. Ten minutes of stretching in the living room counts. Taking the stairs to your flat counts.

Shrink your daily plan for the dark months

A ten-item summer to-do list becomes, in November, a daily reminder that you are falling behind. You have less energy and the same list. That gap is where the constant sense of failure comes from.

It is calmer and more honest to accept the season and rebuild the plan around it.

• Three tasks a day. One main one and two smaller ones. Everything else goes on a separate "if there is energy left" list that you are not allowed to feel bad about.
• The main task goes in daylight hours. Most people think more clearly before lunch, and in autumn the gap between morning and evening gets wider. Put the hard thing first and leave email and admin for dusk.
• Short blocks. When you cannot get started, agree to twenty-five minutes on a timer. Starting for twenty-five minutes is much easier than "sitting down to finish the report".
• A visible end to the workday. In the dark, work spreads into the night because the evening feels lost anyway. Pick a time when the laptop closes and decide what happens straight after.

Keep two or three anchor habits

An anchor is a small action that happens at the same time every day regardless of how you feel. When the summer routine has fallen apart, anchors give the day its shape back.

Two or three are enough. Every new habit costs energy, and energy is exactly what is short right now.

Anchors that work well in autumn:

• getting up at a fixed time and opening the curtains straight away;
• a walk at lunch, however short;
• a proper hot breakfast instead of coffee on the move;
• ten minutes in the evening to write down tomorrow's three tasks;
• dinner at a table instead of in front of a screen.

Missing a day breaks nothing. The more useful rule is never to miss two days in a row: one miss stays an accident, two in a row become the new routine.

Don't let your calendar empty out

Autumn loneliness creeps in without a single decision. You did not turn anyone down. Nobody suggested anything, because it is dark, wet and everyone is tired. A month later you realise the only people you have spoken to are colleagues and the person at the checkout.

Do not rely on feeling like it. In November you will rarely feel like going out, and you will almost always feel better once you have. So plans need to be made in advance and made to repeat.

• One fixed slot a week: Thursday dinner with a friend, Saturday morning coffee with your sister, a Sunday call to your parents.
• Doing something together instead of just "catching up": a swim, a food shop, a dog walk, a five-a-side game. It is easier to show up for an activity than for conversation alone.
• Short formats. Forty minutes in a café near home beats a cancelled evening across town.

If you live alone and work from home, treat this as priority number two after light. Whole days of silence in a dark flat are a direct route from the blues to something heavier.

If your situation is different

General advice lands differently depending on how you live.

Remote workers. The main risk is not leaving the house for days. Office workers at least walk to a station. You need an artificial commute: fifteen minutes round the block before you start and fifteen after you finish. It also gives you a line between work and home.

Students. A drifting schedule plus deadlines on the horizon. Late lectures, late-night revision and sleeping until noon at weekends can mean you see no daylight for weeks. One rule helps most: the same wake-up time even on days without a morning class, and hard study done by day at a library window instead of at night in your room.

Parents of young children. No spare time, but a ready-made reason to be outdoors. Move the pram walk or playground trip to the morning or midday whenever you can. And cut your own list to one task a day: this season, one thing done beats three abandoned.

People with ADHD. Autumn removes outside cues. Light no longer tells you what time it is, and the day blurs into one grey block. External supports help: a timer for short blocks, three tasks written somewhere you can see them, alarms for your anchors. If you take medication and things feel worse in autumn, raise it with whoever prescribes it.

Shift and night workers. You have it hardest, because daylight falls during your sleep. Try to get half an hour outdoors after you wake up, whatever time that is, and keep the same pattern for the length of a shift rotation.

Mistakes that make autumn harder

Waiting to feel like it. In autumn motivation follows action. You step outside first, and then you feel like walking further. If you wait for the mood before you start, you may be waiting until April.

Beating yourself up for being slower. Lower energy in the dark season is how bodies respond to less light. It says nothing about your character. Demanding June speed in November makes about as much sense as being angry that winter is cold.

Treating the evening with a screen. Feeds and short videos distract quickly and do not rest you. The test is easy: compare how you feel after an hour on your phone with how you feel after an hour of walking or cooking.

Putting off the doctor. "It's just the time of year, everyone gets it" is the most harmful explanation when what you have is not what everyone gets. Go back to the table near the top.

When this advice is not enough

Everyday fixes have honest limits.

They will not treat depression or a marked case of seasonal affective disorder. That takes a doctor, with routine and walks as support alongside treatment.

They will not help if the season is not the cause. Tiredness, sleepiness and flat mood also come with anaemia, thyroid problems, recovery from illness and long-term sleep debt. If you have sorted out light, sleep and movement, three or four weeks have passed and nothing has shifted, book a check-up and ask about blood tests.

They do little when the blues sit on top of something heavy: a bereavement, a break-up, burnout, caring for someone who is ill. A walk does not solve a problem that has nothing to do with the weather. Routine is still worth keeping, as a base that leaves you some strength for the main thing, and it helps to have a therapist or a close friend to talk to.

What to do today

Do not try to adopt everything at once. Four steps are enough for today, and they take under an hour.

1. Get outside before three o'clock for at least twenty minutes. No destination needed.
2. Set one alarm time for the whole week, Saturday and Sunday included.
3. Write down three tasks for tomorrow. The main one goes in the morning.
4. Message one person and fix a day and time to meet this week.

In a week, add one anchor from the list above. A week after that, look at what has changed and decide what to add next.

Frequently asked questions

How long do the autumn blues last?

For most people the hardest weeks fall in late autumn and early winter, when the days are shortest, and things ease as the light returns. If your mood stays the same for weeks and does not respond to light or weather at all, the season may not be the cause and it is worth seeing a doctor.

What is the difference between the autumn blues and SAD?

The autumn blues are an informal name for a mild dip: less energy, but life carries on. Seasonal affective disorder is a diagnosis in which low mood lasts for weeks, interest in almost everything drops away and work, sleep or appetite suffer. The first responds to light and routine. The second needs treatment from a doctor.

Should I take vitamin D in autumn?

It depends on where you live and on your own health. Official guidance differs between countries, and the right dose is something to settle with a doctor or pharmacist, not by guessing. A supplement will not stand in for daylight, sleep and movement.

Do SAD lamps work?

Light therapy is used for seasonal affective disorder, with dedicated devices, not ordinary bright bulbs. It is not suitable for everyone, so pick the lamp and the routine together with a doctor. Simply keeping your home brightly lit in the morning is safe and a useful part of a routine.

What if I have no energy for anything at all?

Cut the day down to a minimum you chose in advance: get up at your usual time, eat, spend ten minutes outside. That is enough to stop the day disappearing completely. If this state lasts more than two weeks, it has gone beyond the blues and you should talk to a doctor.

Will a holiday somewhere sunny fix it?

A week of sun in November gives you a break, and many people feel better afterwards. The effect is temporary, though: you come home to the same darkness. A trip works well on top of a routine and poorly as a substitute for one.

Why do I want to sleep and eat carbs all the time in autumn?

Shorter days shift your body clock, so sleepiness arrives earlier and hangs around longer. Carb cravings often travel with tiredness, as your body looks for a quick source of energy. Regular meals, light early in the day and a steady wake-up time all help.

Do It Today makes an autumn routine easier to hold. Write down your three tasks for the day and mark them off as you go, with the main one at the top of the priority board. Set up the walk, the wake-up time and the evening plan as habits and recurring tasks, so you do not have to remember them every morning. When you cannot get started, run the focus timer for a single block. And the history of past days shows that even in the darkest week you got things done, which is encouraging in itself. The tracker is free and installs on your phone as an app.
