Understanding Sundowning: Why Symptoms Often Worsen in the Evening

For many families caring for a loved one with Alzheimer’s disease or another form of dementia, the late afternoon and evening hours can bring unexpected challenges. A loved one who seemed calm throughout the day may suddenly become restless, confused, anxious, or agitated as the sun begins to set. This phenomenon is commonly known as sundowning.

Understanding what sundowning is, why it occurs, and how to manage it can help families provide a calmer and more supportive environment for their loved ones.

What Is Sundowning?

Sundowning refers to a pattern of increased confusion, anxiety, agitation, or behavioral changes that occur later in the day, typically during the late afternoon, evening, or nighttime hours. While sundowning is not a disease itself, it is a common symptom experienced by many individuals living with dementia.

Symptoms may include:

Increased confusion or disorientation
Restlessness or pacing
Irritability or agitation
Mood swings
Anxiety or fearfulness
Difficulty sleeping
Wandering
Repetitive questioning

These symptoms can vary from person to person and may become more pronounced as dementia progresses.

Why Does Sundowning Happen?

Although there is no single cause, several factors may contribute to sundowning:

Fatigue

As the day progresses, individuals with dementia may become physically and mentally exhausted, making it more difficult to process information and cope with their surroundings.

Changes in Light

The transition from daylight to darkness can create shadows and visual distortions that increase confusion or fear.

Disruption of the Body’s Internal Clock

Dementia can affect the brain’s ability to regulate sleep-wake cycles, leading to increased confusion during evening hours.

Hunger, Thirst, or Discomfort

Unmet physical needs such as hunger, dehydration, pain, or needing to use the restroom can contribute to agitation.

Overstimulation

Busy days, excessive noise, or too much activity can leave an individual feeling overwhelmed by evening.

Tips for Managing Sundowning

While sundowning cannot always be eliminated, certain strategies may help reduce symptoms and create a more peaceful environment.

Maintain a Consistent Routine

Predictable daily schedules can provide comfort and reduce anxiety. Try to keep meals, activities, and bedtime routines consistent from day to day.

Encourage Daytime Activity

Regular physical activity and meaningful engagement throughout the day can help promote better sleep at night.

Increase Lighting

As evening approaches, turn on lights throughout the home to reduce shadows and improve visibility.

Limit Stimulants

Avoid caffeine, large meals, or excessive sugar later in the day, as these can interfere with sleep and increase restlessness.

Create a Calm Environment

Reduce noise, lower television volume, and provide soothing activities such as listening to music, looking through photo albums, or engaging in gentle conversation.

Offer Reassurance

If a loved one becomes confused or anxious, respond with patience and reassurance rather than correction. A calm voice and gentle presence can often help ease distress.

When Additional Support May Be Helpful

Sundowning can be emotionally and physically exhausting for family caregivers. As symptoms become more frequent, many families find that additional support allows them to better care for their loved one while also caring for themselves.

Professional caregivers can provide companionship, supervision, assistance with evening routines, and support during the hours when sundowning symptoms are most likely to occur.
