Caring for an aging loved one with Alzheimer’s or another form of dementia brings daily challenges — some expected, others surprising. One of the most confusing and exhausting behaviors families encounter is sundowning. This pattern of late-day agitation can disrupt routines, increase safety risks, and take a real emotional toll on family caregivers.
If you’ve noticed your loved one becoming more anxious, irritable, or confused as evening approaches, you’re not alone. Understanding why sundowning happens and how to respond with calm, supportive strategies can make evenings smoother for everyone involved.
What Is Sundowning?
Sundowning (also called sundown syndrome) is a behavioral pattern in which a person with dementia experiences increased confusion, agitation, or restlessness during the late afternoon and evening hours. About 20% of individuals with Alzheimer’s disease exhibit these symptoms. However, sundowning can occur in people with other types of dementia as well.
Common symptoms of sundowning include:
- Irritability or agitation
- Restlessness, pacing, or wandering
- Confusion or disorientation
- Suspicion or paranoia
- Mood swings
- Yelling or aggressive behavior
- Hallucinations
- Repetitive questions or irrational demands
Sundowning isn’t a formal diagnosis; it’s a cluster of behaviors closely tied to dementia and a disrupted sleep-wake cycle.
What Causes Sundowning?
Researchers don’t know the exact cause of this dementia behavior. However, most agree sundowning is connected to changes in the brain that disrupt circadian rhythms, the internal clock that helps regulate sleep, alertness, and behavior.
Family caregivers often notice sundowning gets worse when:
- Fatigue Builds Throughout the Day: Just like toddlers can melt down when overtired, adults with dementia may become more irritable or confused as the day wears on. Even small disruptions, like an appointment, guests, or a poor night’s sleep, can compound fatigue.
- Lighting Changes: As daylight fades, shadows deepen and visual cues become harder to interpret, which can increase confusion or fear. Shorter days in fall and winter often worsen symptoms.
- Unmet Needs or Discomfort: Pain, hunger, thirst, constipation, or temperature discomfort may not be communicated clearly, but can show up as agitation.
- Medication Timing: Some medications wear off in the late afternoon, leading to irritability or restlessness. Others may cause side effects that peak later in the day.
- Overstimulation or Boredom: Too much noise, clutter, or activity can overwhelm someone with dementia, while too little stimulation can lead to agitation or anxiety.
- Changes in Routine or Environment: Sundowning is more common when an older adult moves to a new home or care setting. A lack of familiar surroundings can heighten confusion.

How Family Caregivers Can Help
There is no one-size-fits-all solution, but many families find relief through small, consistent changes. Here are evidence-based strategies to help manage sundowning symptoms at home.
1. Creating Predictable Daily Routines
A steady rhythm — wake times, meals, activities, and bedtime — helps reduce confusion and calm the nervous system.
Try:
- Keeping mornings active and afternoons calm
- Limiting long or late naps
- Offering meals at the same times daily
Consistency helps seniors feel secure and reduces the likelihood of late-day behavioral changes.
2. Supporting Healthy Sleep
A person with dementia may not be able to communicate what’s disrupting their sleep. So, it’s important to set the environment up for success.
Tips for better sleep:
- Ensure the bedroom is cool, quiet & comfortable
- Reduce noise from TVs, phones, and nighttime activity
- Limit caffeine and sugar after lunchtime
- Avoid alcohol, which disrupts sleep patterns
Some seniors sleep better slightly propped up, such as in a recliner or with additional pillows.
3. Brightening the Environment
Light therapy is a widely recommended tool for sundowning in seniors with cognitive decline. Increasing exposure to bright light in the morning and keeping rooms well-lit as the sun sets can help regulate circadian rhythms.
Try:
- Opening blinds first thing in the morning
- Using a full-spectrum light therapy lamp
- Turning on lamps before the room gets dim
- Using nightlights to reduce disorientation
Reducing shadows and dark corners can immediately decrease anxiety.
4. Encouraging Safe & Enjoyable Activity
Light physical activity during the day helps release restlessness and supports better sleep at night.
Options include:
- A daily walk
- Chair exercises
- Stretching or simple yoga
- Dancing to music
- Household tasks like folding towels
Avoid overstimulating activities late in the day. Instead, opt for soothing music, coloring, or simple puzzles.
5. Creating a Calming Evening Routine
As evening approaches, shift into a quieter environment to help reduce sleep problems.
Try:
- Soft background music
- Familiar objects such as blankets or photo albums
- Aromatherapy using lavender or chamomile
- Warm drinks like herbal tea
- Calm conversation or reassurance
Avoid TV programs with intense plots, fast pacing, or loud noise, which can be confusing or frightening for someone with dementia.

6. Identifying Personal Triggers
Every person experiences sundowning differently. Keeping a behavior diary can help you identify predictable triggers.
Record:
- Time symptoms appear
- What happened earlier that day
- Medications and meal times
- Environmental changes
- Possible stressors
Even subtle patterns can reveal solutions. For example, symptoms starting right as the house gets busy or a particular medication wears off.
7. Making the Environment Feel Familiar
Familiarity reduces confusion. If your loved one recently moved or is in memory care, comforting objects can help reduce symptoms.
Ideas include:
- Family photos
- Favorite blankets or sweaters
- Beloved music
- A familiar chair
- Time with a pet
A sense of belonging often eases agitation in seniors with memory loss.
8. Talking With Their Doctor
Sundowning can sometimes be triggered or worsened by medications, dehydration, untreated pain, infection, or sleep disorders.
A physician may adjust:
- Medication dosage
- Timing of doses
- Pain management
- Sleep aids or melatonin
- Treatment for underlying medical issues
Never adjust medications without medical guidance.
9. Caring for Yourself as a Family Caregiver
Sundowning can be one of the most exhausting symptoms of dementia for family caregivers. Long evenings of pacing, confusion, or agitation can quickly lead to burnout.
It’s okay to need help—truly.
Home care support, respite care, and overnight caregivers can give you the rest you need to stay patient, compassionate, and healthy. Remember: caring for yourself is part of caring for your loved one.
When to Seek Additional Support
Even with the best tools and routines, sundowning can escalate as the disease progresses. If your loved one’s symptoms become unsafe, too frequent, or too overwhelming to manage at home, reaching out for help is essential.
Professional caregivers can help:
- Maintain routines
- Reduce agitation
- Provide supervision during high-risk evening hours
- Support your loved one with personalized strategies
- Give you time to rest and recharge
