Sundowning: Why Evenings Are Hardest for Someone With Dementia, and What Actually Helps
For many families, late afternoon brings a noticeable change. A person who was relatively settled earlier may become restless, confused, irritable, or worried as the day winds down. This pattern is often called sundowning. It can be difficult for the person experiencing it and for the family trying to help.
If you’re caring for someone with Alzheimer’s or another dementia in Dallas, understanding possible triggers and trying a few practical changes may make evenings feel more manageable. There isn’t one approach that works for everyone, but calm routines and a less overwhelming environment can help.
What is sundowning?
Sundowning describes changes in behavior or confusion that begin or become more pronounced in the late afternoon or evening. It is associated with dementia, but it is not a separate diagnosis. The pattern and its triggers can differ from person to person.
Researchers and care professionals point to several factors that may contribute. Dementia can disrupt the body’s sleep-wake rhythms. By the end of the day, a person may also be tired from activity, conversation, or trying to make sense of a busy environment. As daylight fades, shadows and reflections can be harder to interpret, which may add to confusion or fear.
Changes in routine, hunger, pain, illness, medication effects, or too much noise and activity can also play a role. It can help to keep track of what happens before a difficult evening rather than assuming there is only one cause.
What might sundowning look like?
Sundowning can show up in different ways. A person may:
- Become more confused, anxious, irritable, or upset late in the day
- Pace, wander, or repeatedly ask to go home
- Argue, call out, or have a harder time following conversation
- Resist bathing, changing clothes, or other care
- Become uneasy around shadows, reflections, or mirrors
- Seem more alert at night and have trouble settling down
These changes can be stressful, but they are not necessarily intentional. The person may be responding to confusion, discomfort, fatigue, or something in the environment that feels unsettling.
How to make evenings easier
Small adjustments to the day and home environment may help reduce some common triggers. Try one change at a time and notice whether it makes a difference.
Keep a steady daily rhythm
A predictable schedule for waking, meals, activities, and bedtime can provide familiar cues throughout the day. When possible, plan appointments, bathing, and other demanding tasks for the time of day when the person is usually most alert.
Daylight and gentle physical activity earlier in the day may also support a steadier routine. A short walk or time near a bright window can be a simple place to start.
Make the transition to evening gradual
Turn on indoor lights before the room gets dim, and close curtains before dusk so outside shadows are less confusing. Reduce background noise, television volume, and the number of competing activities.
Offer a familiar, low-pressure activity such as listening to favorite music, looking through photographs, folding towels, or having a quiet conversation. A simple supper and a calm pace can make the evening feel less demanding. If late-day caffeine or long naps seem to affect sleep, consider discussing the routine with the person’s care team.
Notice patterns and possible needs
A brief daily note can help you spot connections between an evening’s events and what came before. You might record sleep, meals, activity, medication changes, visitors, or moments when distress began. Patterns can be useful when you talk with a healthcare professional.
Check that the person has had a chance to eat, drink, use the bathroom, and get comfortable. Pain or illness can be difficult to communicate, especially when someone has dementia, so changes in behavior may be an important clue.
What to do in the moment
When distress starts, try to focus on helping the person feel safe rather than proving what is or is not true.
Approach calmly and speak in a gentle voice. Use short phrases and give one simple choice or direction at a time. A reassuring response such as “You’re safe. I’m here with you” may be more helpful than correcting a confused belief or asking several questions.
If the person becomes upset about a shadow or reflection, try changing the lighting, closing a curtain, or moving together to another room. If they resist a task, pause and try again later if it is safe to do so. Redirecting attention to a familiar activity can also help.
Try not to argue, rush, or take the words personally. If pacing is safe, allow some movement while staying nearby and keeping the area clear of tripping hazards. A calm evening plan should also include practical safety steps for your home and the person’s needs.
When to contact a healthcare professional
A new or sudden change should not automatically be treated as sundowning. Contact the person’s healthcare professional if confusion or agitation appears suddenly, becomes much worse, or comes with other concerning changes.
Infection, pain, constipation, dehydration, sleep disruption, and medication side effects can all affect behavior. A clinician can help assess what may be contributing, including whether an infection such as a UTI needs attention. Don’t assume that a behavior change is a UTI or change medications without guidance.
It may help to bring notes about when the change began, what else was happening, and any recent medication or routine changes. If there is immediate danger, a serious injury, or a sudden severe change in the person’s condition, seek urgent help.
For additional guidance, see the Alzheimer’s Association information on sundowning and the National Institute on Aging’s tips for coping with agitation, aggression, and sundowning.
Caregivers need support, too
The hardest hours can become especially challenging when one person is providing care day after day without a break. Respite care can give a caregiver time to rest, take care of other responsibilities, or simply reset. Asking for help is one way to make caregiving more sustainable.
