Check a dementia night-light from the person's usual bed height, both lying down and sitting up. The aim is to catch direct or reflected glare, not to meet a fixed height standard. Australia's July 2024 aged-care guidance sets no required night-light height. It supports shielding strong light sources, using dimmers, and placing lamps to suit the time of day, so the bed-height check is a practical safety step rather than a standardized test (Australian Department of Health and Aged Care).

Why bed height matters
Glare is harsh or uncomfortable brightness that enters the eyes directly or reflects from a surface. From bed, a person may see a lamp, bulb, wall reflection, shiny floor, or bright patch of light that would not be obvious while standing. People with dementia may find glare disorienting.
Strong light can create discomfort, temporary blindness, shadows, or difficulty judging a route, especially during a nighttime trip to the bathroom. Victoria's dementia-friendly design guidance recommends indirect, non-glare lighting and advises against fluorescent lights mounted over beds. A light that sits safely out of the walking path can still be poorly placed if it shines into the person's view.
How to check a light from the bed
test the light at the times when it will be used. Turn it on, lie in the usual sleeping position, then sit on the edge of the bed and look toward the route to the bathroom.
If the light causes discomfort or makes the room seem harder to read, change the angle, height, shade, or location. BrainXchange advises adjusting height and angle for the individual's vision and mobility and screening bulbs with shades or frosted lamps (BrainXchange lighting recommendations).
- Look for the bare bulb or a bright hotspot in the field of view.
- Check whether light reflects from the floor, furniture, mirrors, or glossy doors.
- Move your head slightly, as a person may turn or sit up during the night.
- Ask whether the light feels harsh or makes the route harder to see.
- Repeat the check with the bedroom door open and closed.
What type of placement supports safer movement?
A useful arrangement gives enough light to identify the route without flooding the bedroom. Victoria guidance describes a motion-sensor night-light mounted under a nightstand's apron, with the route from bed to toilet kept clear, as a setup that can support nighttime movement and may aid continence and reduce falls (Victoria Department of Health bedroom guidance). Keep the light aimed at the floor or lower wall rather than at the face.
Avoid placing cords, furniture, baskets, or other obstacles where the person walks. The National Institute on Aging recommends night-lights in the bedroom, hall, and bathroom for people with Alzheimer's disease. It also recommends low evening light and a relaxing bedtime routine, so a night-light should provide wayfinding without making the bedroom brightly lit all night (National Institute on Aging).
What are the limits of a night-light?
A night-light can support orientation and movement, but it does not solve every nighttime problem. The NHS advises reducing glare, shadows, and reflections because better home lighting can reduce confusion and fall risk, while also keeping bedrooms capable of becoming dark at night for sleep (NHS home-environment guidance). Lighting should therefore be adjusted to the individual.
Someone who needs help seeing the route may need more light, while someone disturbed by brightness may need a dimmer source, better shielding, or a different position. Do not treat a night-light as a proven sleep treatment. Evidence for lighting interventions remains mixed: one 24-week nursing-home trial found improved proxy-rated sleep after bright daytime light but no significant improvement measured by actigraphy. The practical goal of a bedside night-light is safer wayfinding with less glare.
Frequently Asked Questions
Is there a recommended night-light height for dementia care?
No fixed height is established in the supplied Australian aged-care guidance. Adjust the light for the person's view, mobility, and route.
Should the bedroom stay brightly lit overnight?
Not necessarily. Use enough light for safe wayfinding, while keeping the bedroom capable of becoming dark for sleep.
Where should I look for glare?
Check the bulb, walls, floor, mirrors, furniture, and any shiny surface visible from both lying and seated positions.
