Sundowning. Sundowner’s Syndrome. Sundowners. These commonly used terms all refer to the behaviors we often see in older persons in private homes, nursing facilities, assisted living facilities, memory care units, and hospitals. Caregivers, hospital staff, and long-term care facility staff see it in their daily work. While not a formally recognized psychiatric diagnosis, “sundowning” is a descriptive term, and is described as:
Being the caregiver for one experiencing sundowning can be stressful and exhausting, and caregivers can become sleep deprived. Behavioral and environmental approaches can be effective in lessening or even preventing some symptoms, and where appropriate should be used as the first line of intervention.
Persons with Alzheimer’s or other dementias are thought to experience sundowning for a variety of reasons, including extreme fatigue, late day lighting, pain, vision problems, hunger or thirst, and depression. These are just a few of the possible causes, and when your loved one is sundowning, determine first what is bothering him or her. This will help you determine how to respond.
Environmental cues can impact a person’s sundowning, adding to their agitation, confusion or aggressiveness. To set up the immediate environment to lessen the symptoms of sundowning, try the following:
- During the daytime, keep window coverings open for maximum exposure to bright light.
- At dusk, close the window coverings and turn lights on to eliminate any shadows caused by the late day light. Shadows can cause confusion for one with dementia.
- Create a quiet routine for the early evening. This might include an early evening walk, or calming background music.
- Minimize loud background noises such as banging pots, or sudden loud noises.
- If needed, create some white noise, the type of noise that is low and in the background. It can help to lessen the impact of sudden noises.
- Minimize clutter in rooms.
- Minimize the number of people in the room;
- Monitor TV watching and the images on the screen. Many TV scenes can be upsetting, especially to one with dementia.
- Structure the day and maintain a stable routine, as much as possible. Routine and structure will help your loved one know what to expect, which is comforting for him.
- Give simple instructions for meals, bathing, etc.
- Eliminate caffeine and alcohol, especially in the late day.
- Include outside physical activity and exercise as part of everyday.
- Keep daytime naps short, and earlier rather than later in the day.
Responding to Sundowning as it Happens
Just as you have tools when loved ones are agitated or fixed on something at other times of the day, you have tools to help them settle down and relax when sundowning.
- Listen carefully. It can be difficult to identify the source of their fear or agitation, but keep listening and try different things to help them calm down. For instance, they may see someone in the room, but maybe it is the shadow created by the light outside the window.
- Redirect where possible. Is it almost time for dinner? Go ahead and eat. Does your loved one like to fold the laundry? Find some, even the laundry that is already folded and in the closet. Pull it out to start all over again. Towels and napkins are always useful for this activity. If it is after dinner and a good night for a walk, go out. Sometimes a TV or a radio program can be a good method to redirect and take their mind off things that are bothering them. Just be careful about the images on the screen.
- Use gentle touch to connect. Hold their hand, stroke their back, hug them. Such touch will be soothing, and may be just what they need.
