8 Useful Tips for Reducing Sundowner’s Syndrome
There are a few tips that can help in reducing the sundowning effects:
Stick to Schedule
Remembering and developing new routines is difficult in those with dementia and can lead to stress, confusion, and anger. This may lead to sundowning. Sticking to the same routine can be helpful and play a role in staying calm. If the change is really needed, try adjusting it gradually.
Light up Their Life
Sundowning may be a result of a disturbance in the circadian rhythm i.e. the sleep-wake cycle. Therefore, adjusting the light at home can reduce the symptoms. A study suggests light therapy can reduce agitation and confusion in people with dementia.(1) Also, if someone is feeling confused brightening the lights can help.
Keep Them Active
People experiencing sundowning have trouble sleeping at night. Too much daytime dozing can make it hard to fall asleep at night. To get a good night’s sleep, being active in the daytime can be helpful.
Adjusting Eating Patterns
Large meals can increase agitation and keep a person up at night, especially after consuming caffeine or alcohol. Encouraging them to avoid these substances at night and having them at lunchtime is better.
Also, limiting evening food intake to healthy snacks and light meals make them more comfortable and rest easier at night.
Minimize Their Stress
Stress can lead to sundowner syndrome. Helping a person with dementia stay calm by doing activities such as watching television, reading, listening to soft music, or having a nice time snuggling with a beloved or a pet, can keep away sundowner syndrome.
Track the Behavior
Different people have different triggers for sundowning. It is always good to identify the trigger and avoid them or work to prevent them. Always look for the patterns of activities or the environment that could be making the condition worse and try and avoid them.
A few non-drug remedies can be helpful in the case of sundowner syndrome. These include:
