Quick answer
When the clocks go back on Sunday 25 October, you gain an hour in bed once, then face weeks of darker mornings that can leave you groggy and out of step. The fix is not willpower, it is light and rhythm. Keep your wake time steady, get bright light into your eyes within the first hour of waking, wind down earlier as the evenings draw in, and make your bed warm and inviting enough that getting up feels less of a battle. A cosy, well chosen duvet does more for a dark October morning than most people expect.
Every autumn the same thing happens. The clocks change, the light disappears from our mornings, and getting out of bed starts to feel like swimming upstream. It is not laziness and it is not a character flaw. It is your body clock, quietly protesting. The good news is that a few small, calm adjustments will settle it far more quickly than gritting your teeth.
Why darker mornings make waking so hard
Your body runs on a roughly 24 hour internal clock, the circadian rhythm, and its single most powerful cue is light. In summer, daylight arrives before your alarm and gently lifts you towards waking. In late October, you are asked to get up in the dark, and your body simply has not received the signal that morning has come. Melatonin, the hormone that keeps you feeling sleepy, is still lingering. That heavy, reluctant feeling has a name, sleep inertia, and dark mornings make it worse.
The clock change itself is only a one hour shift, but it lands right as natural daylight is shrinking on both ends of the day. That combination is what makes the last week of October feel so jarring. If you would like the underlying mechanics in more depth, our guide on how to reset your body clock gently walks through it calmly and without the jargon.
What to do in the week before the clocks change
Shift your evening in small steps
Rather than absorbing the whole hour overnight, move your bedtime and wake time about 15 minutes later each day for three or four days before the change (or 15 minutes earlier, if you prefer to keep your mornings where they are). Nudging your schedule gradually means your body barely notices the shift, instead of lurching into it on the Monday.
Protect your morning light
Light in the first hour after waking is the strongest tool you have. Open the curtains the moment you are up, eat breakfast by the brightest window in the house, and step outside if you possibly can, even for five minutes. On genuinely dark mornings, a daylight or sunrise alarm lamp that brightens gradually before your alarm can take the edge off waking in pitch black.
Dim the evenings
As the mornings get darker, so do the evenings, and bright indoor light late at night tells your brain it is still daytime. Lower the lighting an hour before bed, keep screens dimmer, and let the house feel like it is settling down. This is the same principle behind a good wind down routine, and it matters more, not less, in autumn.
Make waking easier, not just earlier
Half the battle of a dark morning is the moment your feet hit a cold floor in a cold room. If your bed is genuinely the warmest, most comfortable place in the house, waking is still hard, but rising is easier because there is something to move towards, a warm cup of tea, a bright lamp, a room that feels calm. Our piece on how to wake up in winter gathers the practical habits that make the biggest difference once the season turns.
It sounds almost too simple, but people consistently underestimate how much the state of their bed shapes how they feel about mornings. A tired, thin duvet that never quite keeps you warm makes the whole night restless and the morning bleak. A bed that holds its warmth invites deeper, less broken sleep, and you wake feeling as though the night actually did its job.
The autumn bed: warmth without overheating
Late October is duvet changing season. The lightweight summer layers that felt perfect in July leave you reaching for extra blankets by 3am, and a good night starts with getting the warmth right. This is the moment to move to a higher tog, or to a feather and down duvet that traps warm air without feeling heavy.
Natural feather and down is prized for exactly this. It insulates beautifully while staying breathable, so you stay warm through the coldest part of the night without the clammy, overheated feeling that cheaper synthetic fills can cause. If you are unsure which tog or fill suits you, our guide to choosing a duvet by fill, tog and feel is the calmest place to start, and our note on why a feather and down duvet suits winter explains the warmth in a little more detail.
For couples who run at different temperatures, or anyone who finds a single heavy tog too much, layering is the elegant answer. A medium duvet with an easily added blanket lets you fine tune warmth night by night as autumn deepens into winter. Our winter bedding blueprint lays out how to build that layered bed properly.
A short autumn checklist
As the clocks change, it is worth spending twenty minutes getting the bed right for the season: swap to a warmer tog or a feather and down duvet, add a soft blanket you can pull up or push off, put on a freshly washed set of sheets, and make sure your pillows still hold their shape. A bed that is ready for the cold is a bed you sleep more deeply in, and deeper sleep is the real cure for a groggy October morning.

Frequently asked questions
When exactly do the clocks go back in 2026?
British Summer Time ends at 2am on Sunday 25 October 2026, when the clocks go back one hour to Greenwich Mean Time. You gain an hour in bed that night, but the mornings then grow noticeably darker over the following weeks.
Does the clock change really affect sleep?
For most people the one hour shift settles within a few days. The harder part is the loss of morning daylight that comes with it, which can leave you feeling groggy and low on energy for a couple of weeks. Keeping a steady wake time and getting bright light early makes the biggest difference.
Should I go to bed earlier when the clocks change?
Keep your routine steady rather than dramatically earlier. If you want to adjust, shift your bedtime by about 15 minutes a night for a few days beforehand so the change feels gradual. A consistent wake time matters more than an early bedtime.
How do I stop waking up cold in the night as autumn arrives?
Move to a warmer duvet before the cold really sets in. A higher tog or a feather and down duvet traps warm air while staying breathable, so you stay comfortable through the coldest hours without overheating. Adding a light blanket you can pull up or push off lets you fine tune the warmth night by night.
What is the best duvet tog for autumn and winter in the UK?
A 10.5 tog duvet suits much of autumn, while many people move to a 13.5 tog for deep winter. If you prefer flexibility, an all season pairing lets you build up warmth gradually. Our guide to choosing a duvet by fill, tog and feel talks it through in plain terms.
Getting your sleep back on track is about small, kind adjustments rather than sudden overhauls. Get the light right, keep your rhythm steady, and make your bed somewhere genuinely warm and welcoming, and the darker mornings lose a good deal of their sting.
