Sundown syndrome, or “sundowning,” affects many elderly individuals, particularly those with dementia or Alzheimer’s disease. This challenging condition causes behavioral changes as daylight fades into evening. Up to 20% of people with Alzheimer’s experience sundowning symptoms. For family caregivers, managing sundown syndrome every day can be exhausting. Let’s look at some practical, evidence-based approaches to recognize, minimize and manage the effects of sundown syndrome.

What is Sundown Syndrome?
Sundown syndrome, also known as sundowning, is a set of neuropsychiatric symptoms such as confusion, anxiety, agitation, pacing, and wandering that intensify as daylight fades. These behaviors can persist well into the night, disrupting sleep patterns and causing distress.
The exact causes of sundowning are not fully understood, but several factors play a role:
- Disruptions in circadian rhythm
- Fatigue and exhaustion from daily activities
- Changes in lighting and increased shadows
- Hormonal imbalances such as decreased melatonin production
Sundowning primarily affects individuals with dementia, particularly those with Alzheimer’s disease. However, it can also occur in elderly people without dementia, especially those in care facilities or hospitals.
The biological causes of sundowning behaviors are complex. Research shows these causes may be damage to the brain’s cholinergic system and hormonal disruptions (such as problems with the hypothalamic-pituitary-adrenal (HPA) axis) that helps control stress and bodily functions. Additionally, reduced melatonin production in aging people can further disrupt normal sleep-wake cycles.
Recognize the early warning signs
Identifying the early signs of a sundowning episode can help you as a caregiver to intervene quickly and potentially prevent or minimize symptoms. Some behaviors to watch for are:
- Increased restlessness or agitation as the day progresses
- Mood changes, such as becoming more anxious or suspicious
- Difficulty concentrating on tasks
- Pacing or wandering more frequently
- Shadowing caregivers or becoming more clingy
It’s essential to distinguish sundowning from other health issues. Unlike conditions such as delirium, sundowning symptoms typically follow a predictable pattern, worsening in the late afternoon or evening and often improving by morning.
Tracking patterns and triggers can be invaluable for managing sundowning. Keep a simple log noting:
- Time of day symptoms appear
- Duration of episodes
- Potential triggers (noise, visitors, certain activities, and foods)
- Effectiveness of interventions
This information can help identify patterns and develop targeted strategies to minimize symptoms.
Practical Management Strategies
When sundowning symptoms occur, having a toolkit to reduce symptoms can help you respond effectively and with compassion. Here are some practical approaches.
Distraction and redirection techniques
To help redirect and calm your loved one:
- Engage the person in a favorite activity or hobby
- Use calming objects like stress balls or fidget toys
- Redirect attention to pleasant memories or topics of interest
Calming communication approaches
Your tone of voice influences how people with Alzheimer’s respond and react, so be sure to:
- Speak in a soft, reassuring tone
- Use simple, clear language
- Avoid arguing or correcting; instead, validate feelings and redirect
Gentle exercise options
Walking has been shown to reduce the symptoms of sundowning and improve sleep quality. Some ways to engage in gentle exercise with a person exhibiting sundowning include:
- Take a short walk together (if safe and appropriate)
- Practice seated exercises or stretches
- Engage in simple dance movements to calming music
Crisis management for severe episodes
- Ensure the environment is safe and remove potential hazards
- Use calming techniques like deep breathing or gentle touch
- If necessary, contact healthcare providers for additional support
Remember, the effectiveness of these strategies may vary. Be patient and willing to try different approaches to find what works best for your loved one.
Create a soothing environment
Environmental factors play a significant role in relieving sundowning behaviors or making them worse. Making thoughtful adjustments to the living space can create a calming atmosphere that may reduce symptoms.
Optimal lighting arrangements
- Increase indoor lighting in the late afternoon to minimize shadows
- Use nightlights to reduce confusion during nighttime wakings
- Consider light therapy boxes to help regulate circadian rhythms
Noise management
- Reduce background noise from TVs or radios in the evening
- Use white noise machines or soft music to create a soothing ambiance
- Encourage quiet activities as bedtime approaches
Temperature and comfort
Sundown syndrome is linked to changes in body temperature and activity patterns. People with this condition often have:
- Less daytime activity
- More nighttime activity
- Later peak activity times
- Higher average body temperature
- Later peak temperature times
These changes can make their daily rhythms more irregular. To mitigate this, you should:
- Maintain a comfortable room temperature, typically between 68°F to 72°F (or 20°C to 22°C)
- Ensure bedding and clothing are appropriate for your loved one’s environment
- Address any physical discomfort that might contribute to agitation
Familiar and consistent setting
- Keep frequently used items in consistent locations
- Display familiar objects and photos to create a sense of security
- Minimize changes to the environment when possible
Organize the physical space
- Remove clutter to reduce confusion and potential hazards
- Use clear labels or signs to help with navigation
- Consider safety measures like door alarms or motion sensors for wandering prevention
Use these environmental strategies to create a more supportive and calming atmosphere for people experiencing sundowning.
Establish effective daily routines
Consistent daily schedules can significantly reduce sundowning symptoms by providing structure and predictability.
Set a consistent schedule
As a caregiver, you should aim to:
- Wake up and go to bed at the same time each day
- Plan meals and snacks at regular intervals
- Schedule important appointments or activities earlier in the day when alertness is typically higher
Plan meaningful activities
- Engage in stimulating activities in the morning and early afternoon
- Involve the person with Alzheimers in simple household tasks they enjoy
- Encourage reminiscing with photo albums or familiar objects
- Gradually transition to calmer activities as the day progresses
- Avoid overstimulating events or outings in the late afternoon or evening
- Engage in gentle, repetitive activities in the evening like folding laundry or sorting items
Meal timing and dietary considerations
- Keep the table setting and meal simple
- Serve the main meal earlier in the day and allow plenty of time to eat
- Limit caffeine and sugar intake (especially after lunch)
- Offer a light snack before bedtime to prevent hunger-related agitation
Sleep hygiene practices
- Create a relaxing bedtime routine (warm bath, gentle stretching)
- Ensure the bedroom is dark, quiet, and at a comfortable temperature
- Limit screen time and exposure to blue light in the evening
Here’s a sample daily schedule to minimize sundowning triggers:
- 7:00 AM: Wake up, morning hygiene routine
- 8:00 AM: Breakfast and medications
- 9:00 AM – 12:00 PM: Engaging activities (puzzles, crafts, gentle exercise)
- 12:30 PM: Lunch
- 1:30 PM – 3:30 PM: Quiet time or short nap
- 3:30 PM – 5:00 PM: Light activities, increase indoor lighting
- 5:30 PM: Light dinner
- 6:30 PM – 8:00 PM: Relaxing activities (soft music, gentle massage, or a short walk)
- 8:30 PM: Begin bedtime routine
- 9:30 PM: Lights out
Remember to remain flexible. Adjust the schedule as needed based on individual preferences and symptoms.
Medical Interventions and Therapies for Sundowning Symptoms
Interventions without medicine are typically the first line of treatment for sundowning, but medication is necessary in some cases. Always consult with healthcare providers before starting a new medicine.
Medication options
Some of the medicines healthcare providers use to treat the symptoms of sundowning are:
- Low-dose antipsychotics
- Melatonin supplements to regulate sleep-wake cycles
- Cholinesterase inhibitors for Alzheimer’s-related sundowning
Non-pharmaceutical approaches
- Light therapy: Exposure to bright light during the day may help regulate circadian rhythms
- Music therapy: Listening to familiar, calming music can reduce anxiety and agitation
- Aromatherapy: Certain scents like lavender may promote relaxation
Supplements and natural remedies
- Herbal teas (chamomile, valerian root)
- Essential oils for aromatherapy
- Magnesium supplements (under medical supervision)
Discuss any supplements or natural remedies with a healthcare provider to ensure safety and avoid potential interactions with medications.
Addressing underlying health issues
Treating underlying conditions that may contribute to sundowning is crucial. These may include:
- Pain or discomfort
