From Candles to Perfumes: The Science of Aroma and Memory

Did the whiff of a sandalwood candle transport you back to your grandma’s cosy home where you spent the summer holidays? You may have had a Proustian moment—when a scent conjures a memory of an experience gone by. Fragrances can evoke memories of a particular time and place, and there is science behind why the nose knows.

The Link Between Fragrance, Brain, Emotions, And Memories

Research has shown a close relationship between smell, memory and emotion. A familiar aroma can bring a place, person or experience to mind, although the memory and emotional response will differ from one person to another.

When we take in sensory information such as sights, touch or sound, the brain processes it through connected networks. Smell follows its own pathway: scent signals reach the olfactory bulb, which has close links with areas involved in memory and emotional processing, including the hippocampus and amygdala. This connection helps explain why a fragrance can feel especially evocative.

The Business of Fragrances

Businesses have long used aromatic smells to help create a recognisable atmosphere. Scent branding is one way a shop, hotel or other space may try to become more memorable.

A familiar aroma can become part of how people remember a setting. Think of how entering a particular outlet can take you back to earlier shopping trips when its scent has remained familiar over the years.

Introducing Fragrance Into Homes

Since we spend so much time at home, it can be rewarding to make it feel inviting and personal. Fragrance is one way to shape the atmosphere of a room.

Scented candles, incense sticks and diffusers can all introduce aroma at home. Choose a fragrance that suits the room, the occasion and the preferences of the people using the space. Candlelight can also contribute to the ambience of an evening.

How To Select Scented Candle Fragrance For Home

When selecting a scented candle, you do not have to limit yourself to one fragrance. Different rooms and occasions can call for different scent profiles.

For a study space or a child’s room, consider a mild fragrance rather than an overpowering one. Rose, rosemary or another gentle scent may suit households that enjoy fragrance, but it is best to keep the choice subtle and check that everyone using the room is comfortable with it.

For a bedroom, lavender is a popular fragrance choice for creating a quieter, more restful-feeling atmosphere. It can be a pleasant option for winding down, without any expectation that a scent will affect sleep in the same way for everyone.

For bathrooms, fresher or more pronounced notes such as citrus, woody, vetiver, sandalwood or jasmine can help give the room a distinct character. Start with a fragrance you enjoy and adjust according to the size and ventilation of the space.

When choosing a candle for yourself or as a gift, compare the listed fragrance, format and product-page details. Always follow the product’s use and care instructions.
