When the Clocks Change, So Can the Mood - Understanding Sundowning and Dementia
As the nights draw in and the clocks change, many of us feel a little out of sorts. But for people living with dementia, this change can bring a much bigger challenge — something called Sundowning.
Sundowning often happens in the late afternoon or early evening, when fading light and changing routines can lead to increased confusion, agitation, or restlessness.
It’s not just “feeling tired” — it’s the body’s natural clock becoming confused.
🧠 In a healthy brain, our internal body clock (the circadian rhythm) helps us know when to rest and when to be alert.
In dementia, this rhythm can be disrupted, almost like the clock’s batteries are running out. As daylight fades, the brain can lose track of time and send mixed signals — “Should I rest? Should I be up doing something?”
That confusion can feel frightening or frustrating.
When you add the clock change into the mix — darker evenings and a sudden shift in routine — it’s no wonder things can feel unsettled.
So what helps?
💛 Routine, reassurance, and rhythm.
Here’s what we’ve found can make evenings gentler and calmer:
🌞 Late afternoon light & gentle movement
A short walk, a cup of tea by the window — anything that lets in natural light helps reset the body clock.
🍌 A familiar snack or warm drink
Something comforting and easy, like toast or a banana with a warm drink, can help soothe and signal that the day is winding down.
🎶 Background sound — not silence
Soft music, the radio, or a favourite playlist helps the space feel familiar and safe.
🧺 Simple, purposeful tasks
Folding laundry, brushing a pet, or setting the table together keeps hands busy and minds calm.
🕯️ Soft lighting and a sense of cosiness
Dim lights, warm socks, a favourite jumper, and gentle conversation — all small cues that say “It’s time to rest.”
When the world outside feels confusing, consistency and kindness bring comfort and calm.
So as the clocks change this weekend, remember:
The brain needs to be orientated, not isolated.
⏰ A steady routine and a little extra patience go a long way
Here’s an example:
3:30 pm - 4:30 pm - Get outside if the weather allows, soak up the last of the daylight ( and get in some exercise) or sit by the brightest window for a while.
4:30 pm - Simple snack and warm calming drink - starts to comfort the body
5:00 pm - Pop on the radio with some favourite songs and take part in a gentle activity - folding laundry, brushing a pet - think about creating a cosy glow in the home
6 pm- Turn on the radio, keep things reassuring or TV programmes you usually watch at this time - the evening news theme tune helps to give subtle time clues, then eat a meal as you usually would, together.
6:45 pm - Dimmed lights not dark, comfy clothes, warm socks - this gives the brain the message that they can relax and are safe.
