What Is Sundowning?
Sundowning is a term used to describe a pattern of increased confusion, anxiety, agitation or distress that tends to occur in the late afternoon, evening or night. It is most commonly associated with dementia, including Alzheimer’s disease, but it can also affect older people who are frail, unwell or experiencing changes in routine.
For families supporting a loved one at home, sundowning can be one of the most emotionally demanding aspects of care. Behaviour may change as daylight fades, evenings can feel unpredictable, and nights may become disrupted. This guide has been created to help you understand what sundowning is, why it happens, and how it can be supported sensitively and safely in the familiar surroundings of home.

What is sundowning?
Sundowning refers to a worsening of symptoms later in the day, rather than a separate medical condition. Someone experiencing sundowning may appear relatively settled during the morning and early afternoon, then become increasingly confused or unsettled as evening approaches.
Sundowning can involve emotional, behavioural and physical changes. These are not deliberate actions, but expressions of distress, fatigue or confusion. Understanding this can help families respond with reassurance rather than frustration.
Guidance from the Alzheimer’s Society and information provided by the NHS recognise sundowning as a common experience for people living with dementia.
Common signs and symptoms
Sundowning affects each person differently, but common signs may include:
Emotional changes
- Increased anxiety or fear
- Low mood or tearfulness
- Irritability or emotional sensitivity
Behavioural changes
- Restlessness or pacing
- Repetitive questioning
- Calling out or seeking reassurance
- Resistance to personal care
- Increased confusion about time or place
Physical and sleep related changes
- Difficulty settling in the evening
- Disrupted sleep patterns
- Day and night confusion
- Increased wandering risk
Symptoms often follow a similar daily pattern, which can make evenings particularly challenging for family carers.
Why does sundowning happen?
There is no single cause of sundowning. Instead, it is thought to result from a combination of neurological, physical and environmental factors.
Changes in the body clock
Dementia can affect the brain’s ability to regulate circadian rhythms. As a result, the natural signals that distinguish day from night may become less clear.
Fatigue and cognitive overload
By late afternoon, many people are mentally and physically tired. As energy levels drop, coping mechanisms weaken and confusion can increase.
Reduced lighting and visual changes
As daylight fades, shadows lengthen and familiar spaces can appear unfamiliar. This can increase anxiety or lead to misinterpretation of surroundings.
Unmet physical needs
Hunger, thirst, pain, constipation or discomfort may become more noticeable in the evening, particularly if communication is difficult.
Environmental triggers
Noise, busy households, visitors or changes in routine later in the day can contribute to agitation and restlessness.
Understanding individual triggers is an important step in reducing distress and supporting calmer evenings.
Who is most affected?
Sundowning is most often associated with:
- Alzheimer’s disease
- Vascular dementia
- Lewy body dementia
- Mixed dementia
Not everyone living with dementia will experience sundowning, and the severity can vary over time. Symptoms may fluctuate, improving or worsening depending on health, environment and routine. Events such as illness, hospital stays or moving away from familiar surroundings can sometimes make sundowning more noticeable.
The emotional impact on families
Sundowning can be distressing not only for the individual, but also for the people supporting them. Families often describe evenings as tense or exhausting, especially when reassurance is needed repeatedly or sleep becomes disrupted.
Over time, this can lead to emotional strain and fatigue for family carers. Recognising the impact on your own wellbeing is important. Support is not about replacing family involvement, but about strengthening it and ensuring care remains sustainable.
Supporting someone with sundowning at home
While sundowning cannot always be prevented, many families find that consistency, calm and reassurance can significantly reduce distress.
Establishing a steady daily routine
Predictable routines help create a sense of security. Regular times for meals, activities, rest and bedtime can reduce anxiety as the day progresses.
Supporting daylight exposure and activity
Exposure to natural daylight and gentle daytime activity may help regulate sleep patterns and reduce restlessness later in the day.
Creating a calm evening environment
- Gradually increase lighting as daylight fades
- Reduce background noise and visual clutter
- Avoid overstimulation from television or busy household activity
- Keep surroundings familiar and uncluttered
Offering reassurance rather than correction
When confusion increases, correcting facts can sometimes increase distress. Calm reassurance, validation and distraction are often more effective.
Supporting comfort and wellbeing
Ensuring comfort, hydration and appropriate support with pain or discomfort can make a noticeable difference to evening behaviour.
How live in care can help with sundowning
For many families, sundowning is one of the reasons they explore live in care. Having a dedicated carer in the home provides reassurance and practical support during the most challenging times of day.
Continuity and familiarity
A consistent carer builds trust and understands individual routines, preferences and triggers. This continuity is particularly valuable during evenings and nights.
Calm companionship
A live in carer offers gentle companionship and emotional reassurance, helping to reduce feelings of isolation, fear or agitation.
Support through the night
Sundowning does not always stop at bedtime. A live in carer can provide reassurance, support with personal needs and help ensure safety if someone wakes during the night.
Reduced pressure on family members
Knowing that experienced support is in place allows families to rest, reducing exhaustion and helping them remain emotionally resilient.
Remaining at home
Staying in familiar surroundings can significantly reduce confusion. Live in care supports independence while avoiding the disruption that can come with residential moves.
When to seek further advice
If sundowning symptoms suddenly worsen, or appear alongside new physical symptoms, it is important to seek advice from a GP or healthcare professional. While this guide does not provide medical advice, changes can sometimes be linked to treatable causes such as infection or discomfort.
Organisations such as Age UK and the Alzheimer’s Society can also offer guidance, practical information and emotional support for families.
Reassurance for the future
Sundowning can feel overwhelming, but many families find that with the right understanding and support, evenings become more manageable. Small adjustments, consistency and compassionate care can make a meaningful difference.
Live in care offers a flexible, personalised approach that evolves as needs change, supporting both the individual and the people who care about them.
