More memory care communities are thinking about scent as part of the environment they create for residents, alongside lighting, sound, routine and familiar objects. Families and staff often ask which scents are used and why.
This article lists 14 scents memory care communities commonly choose, explains how they fit into a daily routine, and sets out what the research does and does not show. One point up front: Aroma Impressions does not position fragrance as a treatment for dementia, sundowning or any medical condition. Scent is one part of a comfortable, familiar environment, and decisions about it belong with each community's operations and clinical leadership.
What the research shows about scent and memory
One of the more widely reported recent studies came from researchers at the University of California, Irvine in 2023. They gave 43 older adults, aged 60 to 85, an odorant diffuser to use at home. Twenty were randomly assigned to receive seven essential oils (rose, orange, eucalyptus, lemon, peppermint, rosemary and lavender), one per night, for two hours while they slept, over six months. The other 23 used the same diffuser with only trace amounts of scent.
The scented group performed markedly better on a standard word-list memory test than the control group, and brain scans showed changes in a pathway linked to memory and decision-making. Participants also reported sleeping better.
It is a promising result, but it is worth reading carefully. The participants did not have dementia or memory impairment, and the researchers have said that studying people with diagnosed cognitive loss is the next step. It was also a small study of 43 people, funded by a consumer products company.
Studies like this suggest scent is worth taking seriously in memory care, as part of a thoughtful environment rather than as a treatment.

How communities use scent through the day
Many memory care programs are built around a steady daily rhythm, because predictable routines help residents know what comes next. Some communities use scent as one of the cues in that rhythm:
- Mornings. Brighter scents such as citrus or peppermint in common areas as the day starts.
- Mealtimes. Warm, food-like scents such as vanilla, cinnamon or baked goods near dining areas, alongside the real smells of cooking, to signal that a meal is coming.
- Evenings. Softer scents such as lavender or bergamot as the day winds down. Evening can be a difficult time for some residents; a calm environment helps, but scent is not a treatment for sundowning.
Whether to use a schedule like this, which rooms to include and how strong the scent should be are decisions for each community's team.
14 scents memory care communities use
1. Lavender
Soft, floral and herbal. Lavender is one of the most familiar scents there is, and communities often choose it for evenings and quiet rooms because most people find it calm and pleasant.
2. Peppermint
Clean, cool and bright. Peppermint reads as fresh and awake, so it is often used in the morning and in activity spaces.
3. Rosemary
Green and herbal, with a kitchen-garden familiarity. It pairs well with citrus in daytime blends.
4. Bergamot
A citrus note with a softer, slightly floral edge, familiar to many people from Earl Grey tea. It works in both daytime and evening blends.
5. Lemon
Crisp and clean. Lemon is widely associated with freshness and cleanliness, which makes it a common choice for shared spaces.
6. Ylang ylang
A rich, sweet floral. It is usually used lightly, as part of a blend rather than on its own.
7. Ginger
Warm and slightly spicy. Ginger is familiar from cooking and baking and fits naturally into mealtime and seasonal blends.
8. Food scents
Popcorn, fresh bread and chocolate chip cookies are among the most recognizable smells there are. Communities sometimes use them near dining areas as a cue that food is on the way.
9. Vanilla
For many residents, vanilla brings back kitchens, baking and family gatherings. It is warm, familiar and rarely disliked.
10. Citrus
Orange and grapefruit are bright, cheerful scents that suit mornings and common areas where residents gather.
11. Cinnamon
Warm, sweet spice, strongly associated with home baking and the holidays. It works well in mealtime and seasonal programs.
12. Nutmeg
A softer, rounder spice than cinnamon, often blended with vanilla or cinnamon in fall and winter.
13. Pine
Fresh and outdoorsy. Pine can bring a reminder of walks in the woods or the holidays indoors.
14. Floral
Rose, gardenia and other garden flowers can remind people of a grandmother's garden, a wedding bouquet or their own flower beds, which makes florals a natural fit for familiar, home-like spaces.
Practical points for memory care
- Keep it light. In memory care, a scent people barely notice is usually the right level. Every diffuser we install has adjustable intensity.
- Choose familiar scents. Familiar, recognizable scents tend to work better than complex or unusual ones.
- Watch how residents respond. Sensitivities vary. Intensity can be lowered, a unit can be moved, or a scent can be changed at any time.
- Let the community decide where. Which rooms are scented, and how strongly, is the community's call.
How scent is delivered in a memory care community
Cold-air diffusers turn fragrance oil into a fine, dry mist without heat or water, so scent spreads evenly through a space rather than concentrating in one spot. The fragrance oil sits inside the diffuser rather than in an open dish, candle or reed, and units run on a timer, so staff are not refilling or adjusting anything through the day. Larger buildings can also be scented through the HVAC system.
Our library includes more than 200 commercial fragrances, and our fragrance oils are IFRA-compliant and California Prop 65-compliant. We send free samples so staff and families can choose together.
What scent does and does not do
A thoughtful scent program can make a memory care community feel calmer, warmer and more like home, for residents, families and staff. It is not a treatment for dementia, sundowning or any other condition, and it does not replace care, routine or the people who provide them.
