Biological Triggers and Environmental Adjustments for Late Day Agitation
Sundowning can be a confusing and emotional experience for families and their loved ones. This late-day period of increased restlessness, agitation, anxiety, and confusion usually begins in the afternoon or early evening as daylight fades and can continue into the night. It is not a disease, but a pattern of behavior that many older adults, especially those living with memory challenges, can experience. These changes often raise questions about why mood and behaviors shift so noticeably later in the day and what can be done to support calm, comfort, and connection during these vulnerable hours.
Understanding the Biological Triggers
The human body uses an internal biological clock that helps regulate sleep and wakefulness. This internal clock is influenced by the light-dark cycle, which entrains the circadian rhythm. Changes to this rhythm, particularly disruptions in how light affects our sense of time, can directly affect mood, energy, and awareness. Exposure to light earlier in the day helps support a healthy circadian rhythm, whereas a sudden reduction in light in the late afternoon can disrupt the body’s sense of day and night.
Bone tiredness and comfort needs shift with age, and sleep patterns naturally change, making it harder to stay alert during the day and transition smoothly into restful evening routines. Light plays a crucial role, and older adults often become less sensitive to changes in light, making the rhythm less distinct and contributing to confusion later in the day. Disruptions in the sleep-wake cycle can make the later part of the day feel like a blur between daytime activity and a restful night.
Factors such as fatigue, low lighting, hunger, thirst, or unmet emotional needs can increase agitation as the day progresses. For many older adults who may struggle to recognize or communicate these needs clearly, the brain’s response to environmental stimuli can become heightened. This makes shadows, noise, or unfamiliar surroundings seem more confusing and threatening, especially as sunset approaches.
What Happens During Sundowning
Sundowning is often marked by a noticeable shift in mood and behavior as the sun sets. Loved ones may become more demanding, express fear or anxiety, pace, repeat questions, or become restless and easily frustrated. These behaviors typically do not indicate stubbornness but rather reflect how environmental factors and internal rhythms affect comfort and clarity. Some people feel more anxious in dim lighting because of increased shadows or reduced visibility, which can elevate fear and restlessness and make it harder for them to settle for the evening.
A disrupted sleep-wake pattern also contributes to the emotional experience of sundowning. Older adults with sleep challenges often have more awakenings at night or earlier sleep phases. Over time, this can contribute to increased agitation in the late afternoon because the body’s circadian rhythm becomes less distinct. These shifts in rhythm are accompanied by changes in body chemistry and brain signals that make the later part of the day feel unpredictable.
Adjusting the Environment for Calm Evenings
While much remains to be learned about the precise causes of sundowning, environmental adjustments can help create a calm and reassuring space in the late afternoon and evening.
Use Lighting in Supportive Ways
Light plays a powerful role in how we interpret the world around us. Warm evening lighting that is soothing and steady can reduce shadows and confusion. Keeping spaces bright as dusk sets in provides visual stability and makes the environment feel more predictable and less threatening than sudden dimness or darkness. Exposure to brighter light earlier in the day also helps support a healthy sleep-wake rhythm.
Maintain Predictable Daily Routines
Consistency helps the brain anticipate what comes next, reducing confusion and anxiety. A predictable daily routine that includes regular meals, comfortable rest breaks, and meaningful engagement supports a sense of safety. Evening activities that are gentle and familiar, such as listening to favorite music, reading together, or enjoying quiet crafts, facilitate transitions.
Create a Calm Environment
Reducing noise, clutter, and overstimulation is particularly beneficial as the day transitions into the evening. Sudden or loud sounds may feel overwhelming later in the day, so keeping background noise soft and predictable reduces stress. Turning off or minimizing stimulating television programs in the afternoon and evening gives loved ones space to relax and focus on comforting experiences. Soft, familiar items such as cherished photographs and relaxing music help ground individuals in positive memories and provide reassurance when confusion arises.
