In-the-Moment Sundowning Response: What to Do When It Happens

When sundowning hits, your loved one's tired brain is struggling to process the end of the day, and they feel scared, confused, or agitated. You don't need to fix everything in that moment, but you can use a calm, step-by-step approach to help them feel safe and redirect their focus. This guide gives you exact words to say, actions to take, and tools to use right now, based on what experts recommend for dementia caregivers.

Key points

  • Sundowning is caused by a tired, overwhelmed brain, not by willful behavior. Stay calm and do not take it personally.
  • Validate their feeling first: 'I can see you are upset. You are safe. I am here.' Then redirect to a calming activity.
  • Use simple choices (e.g., 'cookie or walk?') to give them a sense of control and distract their brain.
  • Change the environment: dim lights, close curtains, reduce noise, and remove clutter to lower stimulation.
  • Engage their hands with a repetitive task like folding towels or looking at photos to channel anxious energy.
  • Keep a log of when sundowning happens and what helps, so you can anticipate and prevent future episodes.

What Is Happening in Their Brain Right Now

Sundowning is not a choice or a sign of worsening dementia overnight. It is the result of a brain that has been working hard all day and is now exhausted, losing its ability to coordinate sensory information, regulate emotions, and keep a stable internal clock. The part of the brain that controls circadian rhythms, the suprachiasmatic nucleus, has degenerated over time, so the person cannot tell the difference between day and night as easily. This fatigue and confusion can trigger a surge of anxiety, agitation, pacing, repetitive questions, or even hallucinations. They are not being difficult on purpose; their brain's alarm system is going off, and they cannot calm themselves down without your help.

Why Your Reaction Matters So Much

People with dementia live in the here and now, and they pick up on your emotions instantly. If you feel frustrated, angry, or scared, they will mirror that feeling, making the episode worse. Your calm, steady presence is the single most powerful tool you have. When you stay relaxed and use a gentle voice, you signal safety to their overwhelmed brain. The goal is not to argue or correct their reality, but to join them in their experience and gently guide them toward a calmer state. This is called validation and redirection, and it works because it meets their emotional need first.

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. 1. Pause and breathe. Before you say or do anything, take three slow, deep breaths. Remind yourself: 'This is the dementia, not them. I can handle this.' Your calm will be contagious.

  2. 2. Validate their feeling first. Use a warm, gentle tone and say something like: 'I can see you are really upset right now. I am here with you. You are safe.' Do not try to reason or explain why they should not be upset. Just acknowledge their emotion.

  3. 3. Offer a simple choice that involves a pleasant activity. Say: 'Would you like to have a cookie or some ice cream?' or 'Would you like to go for a short walk with me?' Giving a choice (even between two good options) helps them feel in control and distracts their brain.

  4. 4. If they are too restless to sit, switch to a physical activity. Say: 'Let's go for a walk together. We can figure this out while we walk.' Pacing or walking uses up the anxious energy and can help reset their nervous system. Keep the walk short and familiar.

  5. 5. Change the environment to reduce overstimulation. Dim harsh overhead lights and turn on soft lamps. Close curtains or blinds to block confusing shadows from the setting sun. Turn off the TV or loud music. A quieter, softer space helps their brain settle.

  6. 6. Engage their hands in a calming, repetitive task. Offer a familiar activity like folding towels, sorting socks, looking through a photo album, or doing a simple puzzle. Keeping their hands busy gives their brain a new focus and reduces agitation.

  7. 7. Use a gentle, reassuring touch if they are open to it. A light hand on their arm or shoulder, or a slow back rub, can be very grounding. But always watch their body language and stop if they seem uncomfortable.

  8. 8. If they are asking the same question over and over, answer it calmly each time as if it is the first time. Do not say 'I already told you.' Instead, say: 'The appointment is tomorrow at 10 a.m. We will go together. Right now, let's have a snack first.' Then redirect to the activity.

  9. 9. If they are hallucinating (seeing things that are not there), do not argue or try to convince them it is not real. Instead, acknowledge their experience and redirect. For example, if they say there are kids in the back room, you can say: 'I hear you. Let's check on it together. First, let's sit down here and look at these photos.'

  10. 10. Stay with them until the episode passes. Do not leave them alone while they are agitated. Your presence is their anchor. Once they calm down, give them a few minutes of quiet time before moving on to the next part of the evening routine.

What not to do

  • Do not raise your voice or use a sharp tone. This will escalate their fear and confusion. Instead, speak slowly and softly, using simple sentences.

  • Do not argue or correct their reality. If they believe something that is not true (like a missing book), saying 'That never happened' will only make them more agitated. Instead, validate the feeling: 'I can see you are upset about the book. Let's look for it together.'

  • Do not try to reason logically. Their brain cannot process complex explanations right now. Keep your words short and focused on the present moment.

  • Do not force them into an activity they resist. If they say no to a walk, try another option like offering a snack or sitting down with a familiar object. Pushing will increase resistance.

  • Do not leave them alone in a dark or cluttered room. Poor lighting and clutter can worsen confusion and trigger more agitation. Stay with them and adjust the environment first.

  • Do not take their behavior personally. They are not angry at you; they are scared and confused. Remind yourself that this is a symptom of the disease, not a reflection of your caregiving.

Practical tools

  • Calming Phrases to Say in the Moment

    Keep these phrases in your back pocket. Say them slowly and gently: 'I am right here with you.' 'You are safe.' 'Let's take a break together.' 'Would you like a drink of water?' 'Let's look at this photo album.' 'I love you. I am sorry this is hard.' Avoid questions that start with 'Why' (e.g., 'Why are you upset?') because they cannot explain.

  • The 30-Minute Preemptive Activity

    If you know sundowning usually starts around 5 p.m., set a timer for 4:30 p.m. and start a calming, engaging activity that your loved one enjoys. This could be cooking dinner together, doing a puzzle, listening to soft music, or looking at family photos. The goal is to keep their brain focused on a pleasant task before the fatigue sets in. This can prevent or reduce the intensity of the episode.

  • Sensory Calming Kit

    Create a small basket or box with items that soothe your loved one. Include: a soft blanket, a familiar scented lotion (like lavender), a favorite photo album, a simple fidget toy (like a soft ball or textured cloth), and a playlist of calming music or nature sounds. When sundowning starts, bring out the kit and offer one item at a time. Let them choose what feels right.

  • Environmental Quick-Fix Checklist

    Keep this checklist near the light switch: (1) Turn on soft lamps, not overhead lights. (2) Close curtains or blinds to block shadows. (3) Reduce noise: turn off TV, close windows if traffic is loud. (4) Remove clutter from the immediate area. (5) Make sure the room is a comfortable temperature. These changes take less than a minute and can make a huge difference.

  • The 'Let's Do This First' Redirect

    When they are fixated on something upsetting, say: 'We will take care of that. But first, let's have a quick snack / take a short walk / sit down for a minute.' This gives their brain a small, achievable task to focus on, and often by the time the snack is done, the original upset has faded. It works because it does not dismiss their concern, just postpones it gently.

  • Caregiver Self-Cue Card

    Write on an index card: 'This is the dementia. I am calm. I can do this. My job is to help them feel safe, not to be right.' Keep it in your pocket or on the fridge. Read it silently before you respond. This helps you stay grounded and prevents you from getting pulled into their agitation.

Discuss with your clinician

If sundowning episodes become more frequent, more intense, or include new behaviors like aggression or hallucinations that are very distressing, ask the doctor if there are medications that might help, such as low-dose antipsychotics or melatonin for sleep. Do not start any new medication without a doctor's guidance.

If your loved one has a sudden, extreme change in behavior (e.g., new confusion, fever, or physical symptoms), this could be a sign of a medical issue like a urinary tract infection or pain. Contact their healthcare provider immediately.

If you are considering using melatonin or other supplements to help with sleep, discuss the correct dose and timing with the doctor, as it can interact with other medications.

If your loved one is already on medications for dementia (like donepezil or memantine), ask the doctor if the timing of doses could be adjusted to help reduce sundowning symptoms.
