Scent is one of the most powerful yet underrated senses. Unlike sight or sound, which require conscious processing, smell is deeply connected to the limbic system, the part of the brain responsible for emotions, memory, and behaviour. This explains why a whiff of perfume can instantly lift your mood, trigger nostalgia, or even boost confidence.

Fragrance isn’t just about smelling good; it has a profound impact on how we feel, how others perceive us, and even our cognitive performance. Whether it’s the calm of lavender, the sensuality of vanilla, or the energy of citrus, the right scent can transform your mindset and set the tone for your day.

This feature delves into the science of scent psychology, explores how different fragrance notes influence mood, and reveals how you can use perfume as a tool for emotional well-being and self-expression.

1. The Science Behind Scent and Emotion

How Scent Affects the Brain

When you inhale a fragrance, scent molecules travel to the olfactory bulb, which sends signals to the limbic system, the brain’s emotional control centre. This is why scents can evoke immediate and powerful feelings, often without us even realising it.

Key areas influenced by scent:

• Amygdala – Processes emotions like fear, pleasure, and excitement.

• Hippocampus – Connects scent with memory and nostalgia.

• Hypothalamus – Regulates hormones and stress levels.

This explains why a childhood perfume or a loved one’s scent can instantly bring back emotions tied to past experiences.

The Proust Effect: Why Smell Triggers Memory

Coined after Marcel Proust, who wrote about how the scent of a madeleine cake triggered childhood memories, the Proust Effect describes the unique ability of scent to evoke vivid memories and emotions.

• The scent of sunscreen might take you back to childhood beach holidays.

• A whiff of a loved one’s perfume can make you feel instantly comforted.

• The smell of freshly baked bread may remind you of home.

This is why choosing a personal signature scent can create a lasting emotional imprint—on yourself and those around you.
