Not all Confusion is Sundowning
As families notice changes in their loved one’s behavior, the experience can feel confusing, emotional, and at times overwhelming. These changes can feel even more pronounced during seasonal transitions, particularly in the fall, when the sudden shift in daylight can disrupt the body’s internal clock.
For homebound seniors, who rely heavily on consistent lighting and routine, the earlier onset of darkness can create the perception that the day is ending sooner than expected. This can lead to increased confusion, anxiety, or agitation, especially in individuals already experiencing cognitive decline.
These moments are often labeled broadly as “they’re sundowning,” “they’re confused,” or “they’re declining”—but the cause is not always what it seems.
How do you know a loved one is sundowning or something else?
According to the Cleveland Clinic, sundowning is not a random event. It is a time-dependent pattern that typically emerges in the late afternoon or evening. It is best understood as a daily rhythm rather than a one-time occurrence.
Family members may notice:
-Behaviors that begin or intensify later in the day
-A gradual buildup of fatigue
-Repetition of similar behaviors each evening
This pattern is often influenced by:
-Fatigue
-Reduced lighting
-Disruptions in routine
-Changes in the body’s internal clock (circadian rhythm)
The key distinction is predictability. Sundowning tends to follow a consistent, recognizable timeline.
In the sections that follow, we will walk through how conditions like urinary tract infections (UTIs) and dehydration can mimic sundowning.
Urinary Tract Infections: The Hidden Cause
The National Institute of Health reports that urinary tract infections (UTI) in older adults, may not present itself with the typical symptoms many people expect, such as pain, burning, cloudy urine, or fever. Instead, the earliest and most noticeable sign may be a sudden change in behavior or mental status.
A loved one who was stable the day before, may become confused, agitated, withdrawn, or unusually restless within a short period of time. These changes can resemble sundowning, and as a result, UTIs are frequently overlooked or misinterpreted.
Common signs of a UTI may include:
-Increased confusion or sudden disorientation
-Agitation, irritability, or mood changes
-Frequent or urgent need to urinate
-Strong-smelling, dark, or cloudy urine
-Restlessness or changes in usual behavior
In some cases, older adults may not report any physical discomfort at all. This is due to age-related changes in how the body responds to infection, making behavioral changes the primary indicator.
What We Can Do
While age-related changes and underlying medical conditions can increase the risk of urinary tract infections, many of the most common triggers are preventable and directly related to daily care routines. In many cases, UTIs develop when factors are present that allow bacteria to grow and enter the urinary tract easily.
These include:
-Wearing the same brief for extended periods without changing:
Prolonged use of the same incontinence brief can create a warm, moist environment where bacteria thrive. Frequent brief changing is essential to maintaining skin integrity and reducing infection risk.
-Inadequate cleaning after urination or bowel movements: Proper hygiene is critical. Without thorough cleaning, bacteria from the skin or gastrointestinal tract can remain in the perineal area and increase the likelihood of infection.
-Moisture trapped against the skin: Even when briefs are used appropriately, prolonged moisture can lead to bacterial growth and skin breakdown, both of which increase vulnerability to infection.
Incomplete bladder emptying: When urine remains in the bladder, it creates an environment where bacteria can multiply. Encouraging regular toileting and allowing enough time to fully empty the bladder can help reduce this risk.
-Poor hydration: Adequate fluid intake helps flush bacteria from the urinary tract. When hydration is low, urine becomes more concentrated, and the body is less effective at clearing bacteria naturally.
Drink More Water: The Overlooked Trigger
Dehydration is one of the most common, and most overlooked causes of confusion in older adults. It is also one of the few risk factors that directly connects multiple conditions, including urinary tract infections, delirium, and behaviors often mistaken for sundowning.
As the body becomes dehydrated, its ability to regulate temperature, maintain blood flow, and support brain function begins to decline. In older adults, even mild dehydration can lead to noticeable changes in cognition, mood, and behavior.
Because symptoms often worsen gradually throughout the day, dehydration is frequently misinterpreted as sundowning. A loved one may appear more confused, fatigued, or irritable by late afternoon not because of a time-based pattern, but because their fluid intake has been insufficient.
Dehydration also plays a direct role in increasing the risk of infection. When fluid intake is low, the body is less able to flush bacteria from the urinary tract, creating conditions where infections such as UTIs are more likely to develop. At the same time, dehydration can contribute to delirium by disrupting normal brain function and electrolyte balance.
While individual needs vary, clinical guidance suggests that many older adults benefit from a daily intake of approximately 51-68 ounces a day. A practical way to monitor this is to aim for roughly 3 to 4 standard 16-ounce bottles of fluid per day, spaced consistently throughout the day rather than consumed all at once.
Common signs of dehydration may include:
-Fatigue or weakness
-Dry mouth or lips
-Dark or concentrated urine
-Dizziness or lightheadedness
-Increased confusion or irritability
What makes dehydration particularly important is that it is both common and preventable. Unlike sundowning, which follows a pattern, symptoms related to dehydration often improve when fluid intake is restored.
Why The Distinction Matters
Sundowning is a response to fatigue and environmental changes.
UTI's, and dehydration are medical conditions. Treating them the same can lead to delayed care and increased risk.
Family members can look for key differences:
-Timing: Sundowning follows a late-day pattern; medical issues can occur at any time
-Onset: Sundowning develops gradually; medical conditions often appear suddenly
-Consistency: Sundowning repeats; medical conditions may fluctuate or worsen rapidly
Supporting a Loved One—With Awareness
When sundowning is truly the cause, supportive strategies can make a meaningful difference. Maintaining consistent routines, optimizing lighting, reducing evening stimulation, and providing reassurance can help reduce distress.
However, when behavior changes suddenly or feels different from the usual pattern, it is important to pause and contact your medical professional right away. Early attention can prevent complications, support faster recovery, and ensure your loved one receives the care they need.
