Sundowning on the Unit

The same agitation, most evenings, around the same hour. How to tell a real pattern from a new problem wearing its clothes.

NBefore You RespondNotice

Notice what's different about your own attention by six o'clock too. Sundowning isn't only about what's happening in the patient. It's a predictable hour that catches a shift already stretched thinner than it was at noon.

What May Be Happening

Read

A pattern by the clock is different from a change since this morning

If this happens most evenings, around the same hour, and resolves by morning, that's sundowning: a real and common pattern, not a new medical problem each time it appears. If it's new this week, doesn't follow the clock, or doesn't resolve by morning, treat it like new confusion instead and work the reversible causes: pain, a full bladder, hunger, or a missed dose, the same as you would at any other hour.

What's driving the evening pattern

Light and noise drop off exactly when a confused brain needs them most. Fewer visual cues at dusk make it harder to place where you are or what time it is.
Fatigue compounds by the hour, for the patient and for the unit both. A day spent trying to make sense of an unfamiliar room is exhausting, and exhaustion looks like agitation before it looks like tired.
Shift change itself is a trigger. New voices, a new face at the door, a transition nobody can explain in a way that sticks, all arrive right at sundown.

What to Say

Reach

"The day shift is heading home, and I'm here for the night. Let's get you settled."

Naming the transition rather than letting it happen silently around them.

"Let's turn some lights on and see what's outside."

Addressing the light and the orientation cues directly, before addressing the behavior.

"This happens most evenings around this time, and she's safe. Here's what usually helps."

Said to a family member calling in, worried. Naming the pattern reassures better than describing the behavior does.

"Would a call from home help right now?"

Many patients settle faster with a familiar voice on the phone than with anything staff alone can offer.

What Not to Say

"It's just sundowning."

True often enough to become a reason to stop checking pain, the bathroom, and hunger every single evening, which is the one thing that shouldn't stop.

Reaching for sedation before trying light, orientation, and comfort measures first.

That's a physician's call either way, but the environmental steps are cheap, fast, and worth trying first.

Long, detailed reorientation explanations at seven at night.

Short and calm beats accurate and long, especially at the hour attention is shortest.

What to Try Next

Get ahead of it: lights on, curtains open, a clock and the day's schedule visible, before dusk rather than after agitation starts.
Offer the bathroom, a snack, and water proactively around this time, the three most common unmet needs compounding by evening.
Keep the handoff visible. Introduce the night shift by name rather than letting the change happen silently.
Track whether tonight's pattern matches most nights. If it doesn't, work it up as new confusion instead.
Loop in family if a call or a photo from home is likely to help.

When to Escalate

Sedation orders and evening staffing are set by your unit and the treating physician, and this page doesn't replace them. What's worth carrying into that conversation: environmental and comfort measures tried first make the sedation conversation, if it's still needed, a better-informed one.
