As the day progresses into evening, individuals with dementia may experience a phenomenon known as sundowning—a term used to describe increased confusion, agitation, and restlessness that typically occurs during the late afternoon and evening hours. Sundowning can be challenging for both those living with dementia and their caregivers, as the symptoms can lead to increased stress, difficulty settling down for the night, and disrupted sleep patterns.
If you are caring for someone with dementia or Alzheimer’s disease, understanding sundowning and having strategies to help them calm down and feel secure as evening approaches is crucial. While the exact cause of sundowning remains unclear, factors like fatigue, changes in lighting, and confusion about the time of day may play a role. Here’s a closer look at sundowning, what triggers it, and how to help your loved one settle down for the evening.
What is Sundowning?
Sundowning refers to a set of behaviors that emerge in the late afternoon or early evening in individuals with dementia. These behaviors can include:
- Increased restlessness: Individuals may pace, fidget, or have difficulty staying still.
- Agitation or irritability: They may become more easily upset or frustrated, sometimes without a clear reason.
- Confusion: People may struggle with recognizing familiar faces, understanding the time of day, or identifying their location.
- Disrupted sleep patterns: Sundowning can interfere with sleep, causing individuals to become agitated at night and sleep less during the day.
Sundowning isn’t a medical condition itself, but rather a set of symptoms that are commonly associated with various forms of dementia, particularly Alzheimer’s disease. Understanding the factors that contribute to sundowning can help caregivers create an environment that reduces the severity and frequency of these behaviors.
Why Does Sundowning Happen?
The causes of sundowning are not fully understood, but several factors can contribute to the behavior:
- Fatigue and overstimulation: By the end of the day, an individual with dementia may feel physically or mentally exhausted, leading to frustration, anxiety, and confusion.
- Changes in lighting: As daylight fades and artificial lighting takes over, people with dementia may become disoriented, as they can have trouble adjusting to low light or distinguishing between day and night.
- Circadian rhythm disruption: Dementia can interfere with the body’s natural sleep-wake cycle, making it harder for someone to differentiate between day and night, or prompting restlessness when it's time to sleep.
- Hormonal changes: As the day progresses, the body’s production of melatonin, the hormone that signals sleep, may decrease, while cortisol, the stress hormone, can rise—leading to increased agitation.
- Medication side effects: Some medications used to treat dementia-related symptoms can cause agitation or insomnia, which may worsen sundowning.
How to Help a Loved One with Dementia Settle Down for the Evening
While sundowning can be difficult, there are several strategies that can help individuals with dementia transition into the evening and feel more calm, secure, and ready for sleep. Here are some tips to help reduce the effects of sundowning:
1. Establish a Routine
A consistent daily routine can be extremely helpful for individuals with dementia, as it provides structure and predictability. Having a regular schedule for meals, activities, and rest can reduce confusion and help signal to the brain that it’s time to wind down in the evening.
What to do:
- Keep evening routines predictable: Establish a calming routine before bedtime—such as having a light snack, taking a warm bath, or reading a book—that your loved one can come to recognize as a signal that it’s time to relax.
- Avoid large transitions: Minimize any major changes in routine during the evening hours. Sudden shifts, like changing the location of where they sleep or a shift in caregivers, can cause agitation.
2. Reduce Overstimulation
Sundowning often worsens when the individual becomes overstimulated or overtired. As evening approaches, try to reduce distractions and create a calm, quiet environment.
What to do:
- Dim the lights: Avoid bright lights as they can be jarring and disorienting. Instead, use soft, ambient lighting to create a peaceful atmosphere.
- Limit noise: Turn off the TV or loud music, and minimize other background noise that may contribute to restlessness. Gentle, calming music or nature sounds can have a soothing effect.
- Create a quiet space: Set up a quiet area where they can relax without distractions. A comfortable chair or bed, soft blankets, and minimal clutter can help make them feel at ease.
3. Offer Comforting Reassurance
As sundowning causes confusion and anxiety, offering reassurance and emotional support is crucial. People with dementia may become agitated or frightened because they feel out of control or disoriented.
What to do:
- Offer gentle reassurance: Let your loved one know that they are safe, and that everything is okay. Speak in a calm, soothing voice and avoid arguing or raising your voice.
- Use comforting gestures: Hold their hand or offer a reassuring touch. Sometimes, physical contact can provide a sense of comfort and security.
- Remain patient: Be patient if they become upset or agitated. Responding with empathy, rather than frustration, can help de-escalate tense situations.
4. Encourage Physical Activity
During the Day Physical activity helps reduce anxiety, improve mood, and promote restful sleep. Encourage activities during the day that will help your loved one expend energy and feel physically relaxed come evening.
What to do:
- Engage in light exercise: Short walks, stretching, or seated exercises can be beneficial. Physical activity during the day helps regulate the circadian rhythm and can reduce the likelihood of sundowning.
- Avoid heavy exercise late in the day: Strenuous activities late in the evening may be too stimulating and can interfere with winding down for sleep.
5. Maintain a Healthy Diet
What we eat can have a direct impact on our mood, energy levels, and ability to sleep. For people with dementia, maintaining a balanced diet with proper timing can help manage sundowning symptoms.
What to do:
- Avoid caffeine: Try to eliminate caffeinated beverages, especially in the afternoon and evening, as they can interfere with sleep and exacerbate agitation.
- Offer a light evening meal: Large, heavy meals close to bedtime can cause discomfort and restlessness. Instead, offer a light snack or dinner that is easy to digest.
- Hydration: Ensure that your loved one remains hydrated throughout the day, but avoid too many liquids in the evening to prevent frequent trips to the bathroom during the night.
6. Ensure a Comfortable Sleep Environment
Creating an environment conducive to sleep is crucial in managing sundowning. A restful and relaxing atmosphere can help signal to your loved one that it's time to wind down.
What to do:
- Make the bedroom comfortable: Keep the room cool, quiet, and dark. Consider blackout curtains to block out street lights or early morning sun.
- Use calming scents: Essential oils like lavender or chamomile can have a calming effect. Consider using a diffuser or placing a small sachet under the pillow.
Conclusion
Sundowning can be one of the more challenging aspects of caring for someone with dementia, but with the right strategies in place, you can help your loved one feel more relaxed and secure in the evening hours. By establishing routines, reducing overstimulation, offering reassurance, and encouraging physical activity during the day, you can mitigate the symptoms of sundowning and improve their overall well-being. Every person is different, so it’s important to experiment with these strategies to find what works best for your loved one. With patience, empathy, and understanding, you can help create a peaceful transition from day to night and ensure a better quality of life for both you and the person you care for.
