Most children spend their school years learning how to read text, analyze data, and solve equations. Yet, they rarely receive any formal training in how to use their own noses. We give them art classes to train their eyes and music classes to train their ears, while sensory education regarding aromas remains completely ignored in standard curricula.
Dr. Will Tullett, a historian of smells at the University of York, argues that this oversight leaves children unequipped to understand a major part of their sensory environment. Synthetic scents flood modern life, replacing natural aromas in everything from household items to car interiors. At the same time, urban pollution dulls olfactory perception. Without active guidance, kids grow up losing their ability to discriminate between nuanced notes in the world around them.
Why Olfactory Education Matters More Than You Think
Smell is not just about enjoying a nice perfume or avoiding spoiled milk. It links directly to emotional regulation, memory formation, and mental health. Studies show that people suffering from smell loss often experience heightened rates of anxiety and depression. When you cannot properly process aromas, you lose a fundamental layer of connection to your surroundings.
Beyond mental wellbeing, teaching children how to sniff with intention builds practical life skills. Take food safety, for instance. Relying strictly on arbitrary date labels on product packaging leads to massive amounts of household food waste. If kids learn to trust their noses to assess freshness based on actual aroma rather than a printed calendar date, they develop a sustainable habit that lasts a lifetime.
The Problem With Synthetic Scents and Vocabulary Gaps
Modern products are heavily "reodourised." Margarines, cleaning supplies, and packaged snacks often feature artificial chemical profiles that mimic nature without any of the complexity. This constant exposure to one-dimensional scents flattens our collective olfactory palette.
Tullett points out that while people actually care a lot about smells—often sharing vivid childhood memories tied to specific aromas—they lack the vocabulary to discuss them. People want to talk about how things smell, but they lack the confidence and the words. Wine sommeliers solve this exact problem by walking through food markets and deliberately sniffing raw ingredients to expand their mental reference points. Children can do the exact same thing with everyday items in their kitchens, gardens, and local neighborhoods.
Overcoming Olfactory Bias and Social Stigma
There is also a darker side to how we treat smells in society. A common misconception is that historical eras were overwhelmingly foul compared to the present day. In reality, the past did not necessarily stink more; it just smelled different.
Society weaponizes odors to draw lines between groups. Landlords sometimes discriminate against prospective tenants based on biased assumptions about cooking aromas, and public policies have historically targeted vulnerable populations using vague complaints about smells. Teaching children to examine their own reactions to different aromas fosters real empathy. Instead of using scent as an instant trigger for social exclusion, a thoughtful approach helps people understand different cultural contexts and personal preferences.
Simple Ways to Train Your Nose at Home
You do not need a laboratory setup to practice sensory engagement. You can start building better olfactory habits today with things you already own.
- Blind smell tests: Gather three different types of tea leaves or spices from your pantry, close your eyes, and try to identify and describe the subtle differences between them without relying on generic words like "good" or "bad."
- Expand your descriptors: Stop describing scents as merely pleasant or unpleasant. Use descriptive pairs like sweet and earthy, sharp and woody, or metallic and dry.
- Outdoor aroma walks: Take a walk through a park and intentionally notice three distinct plant or soil smells that you usually walk past without a second thought.
Engaging your nose changes how you experience daily life. Give your senses the attention they deserve.
