Why Evenings Can be Hard for People with Dementia
Understanding sundowning — and what you can do about it.
💡Key Takeaways
Evenings can be hard for people with dementia and their caregivers. Learn why and what to do.
- Sundowning is a recognized pattern in dementia where agitation, confusion, and restlessness worsen in the late afternoon and evening.
- Multiple factors converge at day’s end—fatigue, circadian rhythm disruption, low light, and accumulated unmet needs—creating a perfect storm of distress.
- Simple environmental adjustments like gradual lighting changes, eliminating caffeine after 2 PM, and providing sensory activities can significantly reduce evening agitation.
- These behaviors are not your loved one’s choice—they are the brain’s response to overload. You are not failing, and you are not alone.
If you’re caring for someone with dementia, you’ve probably noticed it: the shift that happens as the afternoon fades into evening. Your loved one, who may have been calm or even cheerful during the day, becomes agitated, confused, anxious, or restless as the sun goes down. They may pace, call out, cry, refuse to eat, or become suspicious of the people around them.
This pattern has a name — sundowning — and it is one of the most common and exhausting challenges dementia caregivers face. But understanding why it happens is the first step toward making evenings more manageable for both of you.
What Is Sundowning?
Sundowning refers to a cluster of behavioral and psychological symptoms — including increased confusion, agitation, anxiety, pacing, and mood swings — that intensify during the late afternoon and evening hours in people living with dementia.
According to UCLA Health, sundowning affects approximately of people with dementia. While the exact mechanisms aren’t fully understood, researchers believe it results from a convergence of physical, environmental, and neurological factors that peak at the end of the day.
My Personal Experience with Sundowning
My loved one would start sundowning between 3pm and 4pm every day and it didn’t make any difference where we were, or what we were doing. She began to get suspicious and scared of everything and everyone — this caused extreme anxiety, so if we were out of the house, we’d go home immediately.
I would put soft music on the radio in the car and constantly remind her that everything is okay. Her doctor had prescribed a calming medication to give her when the sundowning started each day. I always had one of those pills to help when she started sundowning.
If we were at my house, she would start getting anxious about a stranger coming into the house. So together, we would go to each door and lock it; then go to each window and pull the blinds. That seemed to ease her anxiety and we could sit together and watch television.
Why Evenings Become Overwhelming
There isn’t a single cause — it’s a perfect storm. Here are the key factors that converge in the evening to create distress:
Fatigue and Cognitive Exhaustion
The brain of a person with dementia is already working harder than a healthy brain to process even simple tasks — recognizing faces, following conversations, navigating a familiar room. By late afternoon, the brain is literally depleted.
This cognitive fatigue lowers the threshold for frustration, confusion, and emotional outbursts. Think of it like a phone battery: by evening, they’re running on 5%, and every notification crashes the system.
Disrupted Circadian Rhythm (Body Clock Shifts)
Dementia damages the suprachiasmatic nucleus (SCN) — the brain’s master clock that regulates our sleep-wake cycle. According to a study published in PubMed, degeneration of the SCN in Alzheimer’s patients leads to fragmented sleep, daytime drowsiness, and nighttime wakefulness.
When the body clock drifts, the brain loses its cue for “it’s time to wind down,” and instead sends signals that feel more like “something is wrong.” This internal confusion amplifies anxiety and disorientation as daylight fades.
“Sundowning is not a choice — it is the brain’s overwhelmed response to a day’s worth of stimulation, fatigue, and failing internal systems.” — National Institute on Aging
Low Light, Shadows, and Visual Misperception
As natural light diminishes, a person with dementia may struggle to interpret what they see. Shadows on walls can look like people or animals. Reflections in windows or mirrors may not be recognized as their own, triggering fear or paranoia.
Depth perception worsens in low light, making furniture appear to shift or doorways seem threatening. The brain, already struggling to process information accurately, fills in the gaps with its best guess — and those guesses are often frightening.
Accumulated Unmet Needs
By evening, small discomforts that a person with dementia cannot articulate may have been building for hours. They might be hungry but unable to say so. They might have a dull ache in their back or a full bladder and not recognize the sensation.
Boredom can feel like restlessness; loneliness can surface as agitation. Because dementia robs people of the language and self-awareness to express these needs, the body expresses them instead — through pacing, crying, calling out, or resisting care.
“When a person with dementia cannot tell you what they need, their behavior becomes the message. Our job is to become better listeners.”
Overstimulation and Sensory Overload
The television is on. Family members are arriving home. Dinner is being prepared — pots clanking, smells mixing, voices overlapping. For a brain that’s already struggling to filter stimuli, the “busy hour” of a typical household can feel like standing in the middle of a highway. Is there any question why evenings can be hard for people with dementia? The Mayo Clinic recommends reducing environmental stimulation during late afternoon to help ease this transition.

Small Changes That Can Make a Big Difference
You don’t need to overhaul your entire routine. Sometimes the smallest adjustments create the most significant calm. Here are evidence-informed strategies you can try today:
Skip Caffeine and Sugar After 2 PM
Caffeine and sugar are stimulants that can linger in the body for hours. For someone with a compromised circadian system, an afternoon coffee or sugary snack can push the nervous system into overdrive right when it needs to be winding down.
Switch to decaf, herbal tea, or water after lunch. Offer a small, protein-rich snack in the mid-afternoon instead — cheese and crackers, half a banana with peanut butter — to keep blood sugar stable and prevent the hunger that fuels agitation.
Dim Lights Gradually to Mimic Sunset
Instead of sudden shifts from bright to dark, create a gentle transition. Use dimmable warm-toned lights (avoid cool/blue-white bulbs, which suppress melatonin) and begin lowering the light level around 4–5 PM.
Close blinds before it gets fully dark to eliminate confusing shadows and reflections. Nightlights in hallways and bathrooms prevent the startle of pitch blackness. The goal is to give the brain a slow, predictable signal that says, “Day is ending. You are safe.”
Offer Calming Hand Activities for Restlessness
Restless hands need something to do. Fidget blankets with zippers, buttons, and fabric patches provide safe tactile stimulation. Folding towels, sorting buttons by color, or gently kneading dough can channel anxious energy into purposeful movement.
For some, simply holding a stuffed animal or a warm cup of tea provides enough sensory grounding to soothe agitation. The key is to offer, not force — let your loved one choose what feels right.
Try a Motion Lamp or Visual Anchor
Lava lamps, bubble tubes, or slow-moving projection lamps can provide gentle, mesmerizing visual stimulation that captures attention without overwhelming the brain. These devices create predictable, calming patterns of light and movement that can redirect focus away from anxiety and confusion. Place one in the room where your loved one spends their evenings, and you may be surprised by how long it holds their attention — sometimes long enough to break the cycle of agitation.
Establish a Predictable Evening Routine
Routine is medicine for the dementia brain. When the internal clock can no longer be trusted, external cues step in. Try to do the same things in the same order each evening: a snack, a favorite show or music, a gentle hand massage, then pajamas and tooth-brushing.
Familiarity reduces the brain’s need to “figure out what’s happening,” which means less anxiety and more cooperation. Even if the routine varies slightly, the rhythm of predictability provides comfort.
“You are not failing. These evening behaviors are a normal part of dementia. You are not alone in this.”
Reduce Evening Noise and Stimulation
Turn off the news (which often features alarming content). Switch to calming music, nature sounds, or a familiar movie. Speak in soft, reassuring tones. Limit the number of people in the room. The less the brain has to process, the calmer it can remain. This isn’t about isolating your loved one — it’s about creating a sensory environment that matches their reduced capacity to filter and cope.
Remember: You Are Not Alone
If you dread the evenings, please hear this: what you’re experiencing is one of the most common challenges in dementia caregiving. Most caregivers discover that evenings can be hard for people with dementia at some point during the disease. It can happen during any stage.
Sundowning is not caused by something you did wrong. It is not a sign that your loved one is “getting worse because of you.” It is the brain’s overwhelmed response to a disease that is beyond anyone’s control.
Millions of caregivers around the world face this same sunset struggle every single day. Support groups — both in person and online — can provide strategies, empathy, and the simple comfort of being understood. Organizations like the Alzheimer’s Association offer 24/7 helplines and local caregiver support.
You are doing something incredibly hard, and the fact that you’re reading this article means you’re looking for ways to do it even better. That matters. You matter. Remember to take care of yourself.
