Understanding and Easing Sundowning in Dementia Care

As the day transitions into evening, many caregivers observe a noticeable change in their loved ones with dementia. This phenomenon, known as sundowning, is characterized by increased confusion, agitation, and restlessness during the late afternoon and evening hours.

These changes can be unsettling, especially when they disrupt what might otherwise be a calm end to the day. But understanding why sundowning happens—and learning how to respond with confidence and compassion—can ease the strain for everyone involved.

What is Sundowning?

Sundowning refers to a pattern of increased confusion and agitation that occurs in the late afternoon and evening of many individuals with dementia. While the exact cause is not fully understood, several factors that may contribute include:

• Circadian Rhythm Disruption: Dementia can affect the body’s internal clock, leading to confusion about the time of day.
• Fatigue: As the day progresses, individuals may become tired, making it harder to cope with stress.
• Low Light and Shadows: Reduced lighting can cause misinterpretations of the environment, leading to fear or confusion.
• Hunger or Thirst: Unmet physical needs can exacerbate irritability and restlessness.
• Overstimulation: A busy or noisy environment can overwhelm someone with dementia, especially later in the day.

Symptoms of sundowning can vary but often include:

• Increased confusion or disorientation
• Agitation or irritability
• Restlessness or pacing
• Mood swings
• Hallucinations or delusions
• Attempts to leave or “go home”

These behaviors can be challenging, but with patience and the right approach, they can be managed effectively.

Strategies for Managing Sundowning

Managing sundowning requires a compassionate and proactive approach. The following strategies are designed to address common triggers, promote comfort, and create a soothing rhythm to the day and evening.

1. Establish a Consistent Routine

A predictable daily schedule provides a sense of structure and security. Aim to:

• Keep waking, meal, and bedtimes consistent.
• Schedule more stimulating activities earlier in the day.
• Limit daytime naps to avoid interfering with nighttime sleep.

Consistency helps anchor the day and reduce the anxiety that often fuels sundowning behaviors.

2. Create a Calming Environment

Environmental cues can significantly impact a person’s mood and behavior:

• Use soft, steady lighting in the evening to reduce shadows.
• Close blinds before dusk to reduce visual confusion.
• Keep background noise low and eliminate clutter.
• Choose soothing music, familiar scents, or comforting textures.

These environmental adjustments can make the space feel more secure and less overwhelming.

3. Address Unmet Physical or Emotional Needs

Sometimes agitation is a sign that something else is wrong:

• Is your loved one hungry, thirsty, in pain, or needing the bathroom?
• Are they overstimulated, bored, lonely, or scared?

Responding quickly and gently to these cues helps resolve discomfort and restores calm.

4. Engage in Meaningful Daytime Activities

Staying engaged throughout the day can help reduce pent-up energy that surfaces later. Try these activities to help release the energy:

• Folding towels, sorting objects, or watering plants.
• Looking through photo albums or listening to favorite songs.
• Doing light exercises or going for a short walk outside.

Activities should match your loved one’s abilities and interests and end well before evening.

5. Use Reassuring Communication

What you say—and how you say it—can make all the difference:

• Speak slowly and gently, using short, simple sentences.
• Maintain eye contact and use calming gestures.
• Validate emotions instead of arguing or correcting.

Reassurance, presence, and tone are often more important than exact words.

6. Monitor Diet and Hydration

Poor nutrition and dehydration can contribute to irritability and confusion:

• Offer balanced meals on a predictable schedule.
• Encourage water intake throughout the day.
• Avoid caffeine after mid-afternoon, and limit alcohol intake altogether, especially in the evening hours when its effects can contribute to restlessness or disrupted sleep.

Nutrition habits affect not only physical health but emotional balance as well.

7. Encourage Exposure to Natural Light

Natural light helps regulate the sleep-wake cycle:

• Open blinds to let in daylight.
• Sit outside for fresh air and sunshine.
• Use full-spectrum light bulbs during darker months.

A well-lit environment helps cue the brain that it’s daytime and supports better sleep later.

How Aegis Living Uses Light Therapy to Support Residents

At Aegis Living, we’ve found that light therapy can be a gentle yet powerful way to support residents experiencing symptoms of sundowning. By aligning daily lighting with natural circadian rhythms, we help create a sense of stability and ease that’s especially important for individuals living with dementia.

Our communities often use specialized light boxes or natural-spectrum lighting in the morning hours to help cue the brain that it’s time to wake up and engage. As the day progresses, lighting is gradually softened to mimic the setting sun, reinforcing the body’s natural winding-down process.

Families have shared that their loved ones seem more settled in the evenings and better able to rest at night. While light therapy isn’t a one-size-fits-all solution, it’s one of many thoughtful approaches we use to create a calm, supportive rhythm to the day.

A Calmer Way Forward

Sundowning presents unique challenges in dementia care, especially for caregivers who are already stretched thin. But with a combination of empathy, consistency, and simple daily adjustments, it is possible to create greater peace and predictability as the day winds down.

As dementia care educator Teepa Snow reminds us, “It’s not about fixing the person. It’s about figuring out what’s causing the distress, and then being a detective to make things better.”  That shift—from control to compassion—is often the turning point in how we respond to sundowning.

With the right tools and mindset, caregivers can find moments of calm, build trust, and support their loved one with greater confidence—even when the evenings are tough.
