Sundowning in Dementia: What Helps
A calm, step-by-step plan for the late-afternoon storm, from an occupational therapist who has lived it at home.
What helps sundowning most is getting ahead of it: morning daylight, an active morning, one short early nap, a 3 p.m. snack-and-water break, bright lights on before dusk and a quiet evening. In the moment, lower the noise, offer a calm familiar task and reassure the feeling instead of arguing with the facts.
What sundowning looks like
Sundowning is a pattern of extra confusion, worry or agitation that builds in the late afternoon and evening. It often starts around 3 or 4 p.m. and can carry on into the night. Mornings are usually better.
The Alzheimer's Association describes it as a set of symptoms, not a disease of its own. You may notice:
- Pacing, fidgeting or opening and closing drawers
- Anxiety, tears or snapping at small requests
- Asking to "go home" even when they are home
- Fear of shadows or seeing things in dark corners
- Trouble settling down for bed
A simple test: if two or more of these happen mostly late in the day, and mornings are calmer, you are probably seeing sundowning.
Why it happens in the late afternoon
No one knows the exact cause, but several things tend to pile up by late afternoon:
- A tired brain. Making sense of the world takes a lot of effort with dementia. By 4 p.m., the tank is empty.
- Fading light. Dim rooms and long shadows are easy to misread, and aging eyes need more light.
- A broken body clock. Dementia can disrupt the brain's sense of day and night.
- Unmet needs. Hunger, thirst, pain or a full bladder that they can't put into words.
- A busy house. TV, cooking, phones and family arriving all at once.
- Your stress. People with dementia often pick up on our tension, even when we hide it.
Hidden medical problems can also hide behind a "bad evening": constipation, a urinary tract infection, restless legs, sleep apnea, dehydration or a new medicine. The Alzheimer's Association recommends talking with the doctor about physical problems like these, because treating them can ease the confusion.
The good news: many of these triggers are things you can change at home.
What to do in the moment
When sundowning starts, your goal is not to win the argument. It is to bring the temperature down.
- Lower the noise. Turn off the TV and speak slowly and softly.
- Turn on every main light and close the curtains. Bright, even light removes the shadows that feed fear.
- Check the basics. Offer a drink, a small snack and the bathroom. Ask, "Does anything hurt? Show me where."
- Offer a calm, familiar task. Folding towels, sorting socks or looking at photos resets the moment better than words.
- Answer the feeling, not the facts. If they want to go home, ask about home. If they're scared, say you'll keep them safe.
- If pacing helps, let them walk. Walk with them in a safe space instead of insisting they sit.
Avoid arguing, rushing, or holding them back physically. Those almost always make things worse.
Keep your own voice and body calm
Your tone matters more than your words. Get to eye level, slow your breathing, relax your shoulders and keep sentences short. Offer one choice at a time: "Tea or water?" is easier than "What do you want?"
If you feel your own patience slipping, it's okay to step away for a minute once they're safe. Take a few slow breaths in the next room, then come back. A calm caregiver is the most powerful sundowning tool in the house.
Prevent it tomorrow: the afternoon defense
Sundowning starts long before dark. These changes, started together and kept up for about two weeks, give the best chance of calmer evenings:
- Morning light. Open curtains right away and serve breakfast by the brightest window. Go outside if you can.
- Midday movement. A walk, chair exercises or a simple chore before lunch.
- One short nap. If they nap, keep it short, early (before about 2 p.m.) and in a chair, not in bed.
- A 3 p.m. pit stop. Snack, water, bathroom and a favorite song before the crash hits.
- Hard things in the morning. Move baths, errands, appointments and visitors to their best hours.
- Lights on before 4 p.m. Put main lamps on timers or smart plugs so the house handles sunset for you.
- A lighter dinner. The Alzheimer's Association suggests a bigger lunch and a lighter evening meal.
- Cut stimulants. Switch to decaf after lunch and limit alcohol, as advised by the Alzheimer's Association and Mayo Clinic.
Dr. Vera's OT tips: set up the house for dusk
As an occupational therapist, I look at the room before I look at the person. Small changes to the home often do more than any conversation.
Walk your house at dusk
Once this week, walk through the house at 5 p.m. and look for dark hallways, a single lamp in a big room, mirrors or glass doors that reflect at night, and coats hanging where they look like people. Add lamps, cover reflective glass and move the coats.
Make a busy basket
Fill a basket with towels to fold, socks to match and cards or coupons to sort. Hand it over at 4 p.m. with "Could you help me with these?" Purpose calms restless hands.
Give the evening a soundtrack
Pick a few slow songs from their teens and twenties and play them every afternoon at the same time. Over time, the music itself becomes a cue that it's time to slow down.
Set a reminder for yourself
Set a phone alarm for 3:30 p.m. that says "Lights on, snack, music." It's much easier to prevent the storm than to calm it.
When evenings bring "I want to go home"
One of the most common sundowning moments is the evening request to go home, often while they are sitting in the house they've lived in for decades. They may pack a bag, look for their coat or try the front door.
"Home" is usually a feeling more than a place: safety, comfort, a time when life made sense. Evening confusion can make even their own living room feel strange. That's why correcting them ("You live here!") rarely works.
- Ask and listen. "Tell me about your home. What's your favorite room?"
- Meet the need. Offer a snack, photos, or a short walk outside, then "come home" together.
- Buy time kindly. "We'll go after dinner. Let's eat first." Often the urge passes.
- Plan for safety. Add door chimes or alarms so you know right away if they try to leave.
A trick many families find helpful: keep a "going home" bag by the door with a sweater and a few photos. Carrying it can be enough to end the search.
Track it for two weeks
Sundowning has patterns, and a simple diary helps you find them. Each day, jot down:
- What time the confusion started
- What happened just before (a bath, a visitor, a skipped lunch, a long nap)
- What calmed them
- How they slept that night
After two weeks, compare. Is it starting later or ending sooner? Did the bad days follow busy afternoons? Bring the diary to the doctor, too. It is far more useful than trying to remember.
When to call the doctor (and when to call 911)
Call the doctor soon if:
- Sundowning suddenly gets much worse, or appears out of nowhere. A sudden change can be a sign of infection (such as a urinary tract infection), delirium, constipation or a medication side effect.
- There are signs of pain: grimacing, guarding a body part, moaning.
- They are seeing people or animals that aren't there, especially if this is new.
- They try to leave the house often.
- A new medicine or over-the-counter sleep aid was started recently.
Ask for a medication and pain review. Don't start, stop or change any medicine, supplement or sleep aid on your own; the Alzheimer's Association notes that non-drug approaches are generally tried first.
Call 911 if anyone is in immediate danger, they are missing after a short search, they fall and hit their head, or they have chest pain, trouble breathing, face drooping, arm weakness, slurred speech or suddenly can't be woken.
You don't have to figure this out alone. The Alzheimer's Association 24/7 Helpline is 1-800-272-3900, including the middle of the night.
Be kind to yourself
Sundowning is not your fault, and it is not your loved one being difficult on purpose. It is the disease, showing up at the hardest time of the day, often when you're tired too.
Protect your own evening, too. If you can, have a snack and a glass of water at the 3 p.m. pit stop with them. Ask family to visit at brunch instead of dinner so the house stays quiet, and ask someone to take over one evening a week so you get a real break. A rested caregiver has more patience, and your loved one feels the difference.
Some evenings will still go badly, even when you do everything right. That's normal. Pick one or two changes from this page, give them two weeks, and build from there. Small wins add up to calmer evenings for both of you.
Say this, not that
Say“I'm right here. We're safe.”
Not“Calm down, nothing is wrong.”
Reassurance meets the feeling. Telling someone to calm down tells them their fear doesn't count.
Say“Could you help me fold these towels?”
Not“Just sit down and relax.”
A familiar, useful task gives restless energy somewhere to go.
Say“You miss home. Tell me about it.”
Not“You ARE home. This is your house.”
"Home" is often a feeling of safety. Arguing the facts makes the search more urgent.
Say“Let me make it brighter so we can see.”
Not“There's nobody there. Stop it.”
Fixing the light fixes the fear without making them feel foolish.
Say“We can do that tomorrow.”
Not“We have to get this done now.”
Late afternoon is the worst time for demands. Save hard tasks for their best hours.
Questions families ask
What time of day does sundowning start?
It usually starts in the late afternoon, often around 3 to 5 p.m., and can last into the evening or night. The timing varies from person to person, which is why a simple two-week diary helps. Once you know your loved one's pattern, you can schedule a snack, water, lights and a calm activity just before it usually begins.
Can sundowning be stopped completely?
There's no guaranteed cure, but many families see shorter, milder episodes with a steady routine, morning daylight, daytime activity, limited naps, bright evening lighting and a quiet evening. Treating hidden problems like pain, infection or medication side effects can also make a big difference. Give any set of changes about two weeks before judging the result.
Does sundowning mean dementia is getting worse?
Not necessarily. Sundowning can happen at different stages and can come and go. A sudden change, though, deserves a call to the doctor, because infections, pain, constipation, dehydration and new medicines can all make evening confusion worse quickly. Treating the cause often brings things back to their usual level.
Should I give melatonin or a sleep aid for sundowning?
Talk to the doctor or pharmacist first. Many over-the-counter sleep aids and "PM" products can increase confusion and fall risk in older adults. Even natural supplements can interact with other medicines. Ask whether any option is safe for your loved one, and try non-drug steps such as light, routine and calm evenings at the same time.
What is the best activity for sundowning?
Simple, familiar and calming works best: folding towels, matching socks, looking at photos, listening to favorite music, a short walk, or a hand massage with lotion. Start it yourself and invite them to help. Activities earlier in the day, around 2 p.m., can also head off the late-afternoon crash.
This guide is education, not medical advice. Every person with dementia is different. A sudden change in behavior, confusion, sleep or movement can have a medical cause, so call the doctor when something changes quickly. In an emergency call 911.
