Sundowning in Dementia: Why Evenings Are Harder

๐Ÿ“… June 25, 2026 ✍️ By Piewy Team

Many clients with dementia become more confused, restless, or agitated in the late afternoon and evening. This is called "sundowning," and simple strategies can ease it.

What Is Sundowning?

Sundowning is a pattern of increased confusion and agitation as daylight fades. The exact cause isn't fully understood, but tiredness, low light, hunger, and disrupted body clocks all play a part.

Common Triggers

  • Fatigue at the end of the day
  • Dim lighting and shadows
  • Hunger or needing the toilet
  • Too much noise or a busy shift change

How PSWs Help

  1. Keep rooms well-lit in the late afternoon.
  2. Keep a calm, predictable evening routine.
  3. Reduce noise and stimulation.
  4. Offer a snack and a toilet trip.
  5. Encourage activity and daylight earlier in the day.
  6. Stay calm and reassuring if agitation rises.

What to Report

Report worsening patterns so the care team can adjust routines and rule out pain or infection.
