Understanding the Sundowning Effect in Dementia: How to Calm the Storm Before Nightfall
It’s late in the afternoon, and suddenly, everything changes. The person who was calm just an hour ago now seems restless, anxious, maybe even aggressive. They start pacing, looking confused, or struggling to understand what’s happening around them. Their world becomes more difficult to navigate, just as the sun begins to set.
This phenomenon is called sundowning, a common and often distressing symptom of dementia. It affects individuals in the late afternoon and evening, bringing increased confusion, agitation, and sometimes paranoia or hallucinations. If you are a caregiver, witnessing this transformation can be heartbreaking. But with the right approach, you can help your loved one find peace in the midst of the storm.
Why Does Sundowning Happen? Understanding the Root Causes
Sundowning isn’t just random, it’s driven by real changes in the brain that dementia causes. Here’s what could be triggering these evening struggles:
Disrupted Internal Body Clock (Circadian Rhythm): Dementia damages the brain’s ability to regulate sleep-wake cycles, leading to confusion as day transitions into night.
Low Light & Shadows: As daylight fades, shadows can become frightening, causing misinterpretations or even hallucinations.
Fatigue & Overstimulation: After a long day of activity, exhaustion can trigger increased confusion and irritability.
Hunger or Thirst: Missed meals or dehydration can make agitation worse, even if they cannot express it.
Unmet Needs: Physical discomfort, pain, or the need to use the bathroom can create restlessness.
By addressing these root causes, you can reduce the impact of sundowning and create a calmer evening environment.
How to Manage Sundowning: Proven Strategies to Bring Comfort
Sundowning can be unpredictable, but you can take steps to manage it. Here’s how:
Maintain a Routine: A structured day provides stability. Try to keep mealtimes, activities, and bedtime consistent to reduce anxiety.
Optimize Lighting: As daylight fades, ensure rooms are well-lit to minimize shadows that might be misinterpreted. Consider soft, warm lighting to create a soothing environment.
Encourage Daytime Activity: Exposure to sunlight and light exercise during the day can help regulate their internal clock, leading to better sleep at night.
Provide Comfort & Reassurance: If they become agitated, avoid arguing or correcting them. Instead, speak calmly, offer a reassuring touch, and redirect their attention to something comforting.
Limit Stimulants: Reduce caffeine, heavy meals, and screen time in the evening. Opt for light, easily digestible foods and calming activities before bed.
Create a Calming Evening Atmosphere: Play soft music and engage them in relaxing activities like looking through a photo album or listening to a familiar story.
Conclusion: Helping Your Loved One Find Peace in the Evening
Sundowning can be one of the most challenging aspects of dementia care, but you are not powerless against it. By understanding its triggers and implementing the right strategies, you can create an environment that soothes rather than agitates.
Dementia may steal memories, but love, patience, and a sense of security can always bring comfort. Your care matters, and with each small step, you’re helping your loved one feel safe, even as the sun sets.
