Did you know that some people can identify hundreds of different scents in a single perfume? Tea experts can even tell where a tea was grown, the season it was harvested, and what kind of tree it grew near. In New York City, there was once a person whose job was to sniff out gas leaks in the subway. These people have trained their noses to be super sensitive, but can anyone learn to smell like them?
For most of us, smelling is something we do without thinking. We might catch a whiff of garbage behind a restaurant, the scent of shampoo from someone in an elevator, or the delicious aroma of freshly baked bread. Our noses have millions of olfactory receptors, which means we have the potential to smell well, but we often don’t pay much attention. This is a shame because smells are closely tied to our emotions and can bring back memories of people and places we love.
The good news is that you can train your brain to improve your sense of smell. Helen Keller, for example, could recognize different professions just by smelling. Here are some steps you can take to enhance your sense of smell:
Animals like dogs and pigs, known for their excellent sense of smell, get their noses right up to the source of the scent. Humans usually smell from a distance. To improve your sense of smell, try getting closer to the ground, surfaces, objects, and even the food you’re about to eat.
Smelling happens in a small area near the bridge of our noses called the olfactory epithelium. When you sniff, odor molecules enter your nostrils and reach this area, where they meet your scent receptors. Taking a few sharp sniffs helps more air reach these receptors, making it easier to detect smells.
Many smells go unnoticed because we don’t focus on them. By consciously identifying and describing what you’re smelling, you can expand your scent vocabulary. When an odor molecule binds to a receptor, it sends a signal to your brain, where it’s processed along with taste, memory, and emotions. Research shows that spending more time focusing on scents can change how experienced smellers perceive odors.
To start training your nose, use ingredients from your kitchen like spices or fruits (make sure they’re safe to smell). Close your eyes and have someone bring them close to your nose. Sniff and try to identify what you’re smelling. Over time, you’ll start to notice subtle differences in familiar smells and recognize new ones.
While perfumers might practice these techniques to become experts, you don’t have to go that far. Simply improving your sense of smell can make your everyday experiences more enjoyable and memorable.
Explore your surroundings and create a list of different scents you encounter throughout the day. Try to identify at least ten distinct smells, such as the scent of grass, a specific food, or even a book. Write down what you think each scent is and where you found it. This will help you become more aware of the variety of smells around you.
Gather a few common household items with distinct smells, like vanilla extract, lemon, or coffee. Have a friend or family member blindfold you and present each item for you to sniff. Try to identify each scent and then discuss any memories or emotions they evoke. This activity will help you connect smells with memories and emotions.
Create a piece of art inspired by a particular scent. Choose a smell that you find interesting or meaningful, and use colors, shapes, and textures to represent how it makes you feel. Share your artwork with your classmates and explain the connection between the scent and your creation. This will encourage you to think creatively about how smells influence your perceptions.
Bring a small, scented item to class and prepare a short presentation about it. Describe the scent, where it comes from, and any interesting facts about it. Allow your classmates to smell the item and share their thoughts. This will help you practice describing scents and expand your scent vocabulary.
Conduct a simple experiment by mixing different spices or essential oils to create a new scent. Record the combinations you try and describe the resulting smells. Share your findings with your classmates and discuss which combinations were most pleasant or surprising. This will help you understand how different scents interact and enhance your ability to identify complex aromas.

Perfumers can learn to distinguish individual odors in a fragrance made of hundreds of scents. Tea experts can identify not just the location of a tea’s origin, but also the season of harvest and even the type of tree it was planted near. Interestingly, the New York City Transit Authority once had an employee dedicated solely to detecting gas leaks in the subway system.
Can anyone learn to smell with the sensitivity of these experts? For many of us, our sense of smell is largely involuntary. We might notice the garbage behind a restaurant, the scent of shampoo from someone leaving an elevator, or the aroma of freshly baked bread from a bakery. With millions of olfactory receptors in our noses, we certainly have the capacity to smell well; we just might not always pay close attention. This can be unfortunate, as we may miss opportunities to form strong emotional connections. Smells are closely linked to emotions and can evoke memories of places we’ve left behind and people we’ve cherished.
Fortunately, it is possible to train our brains to enhance our sense of smell. For instance, Helen Keller was able to recognize different professions by simply inhaling. Here are some steps you can follow to change the way you perceive smells:
1. **Get Close**: Some animals known for their keen sense of smell, like dogs and pigs, put their noses right at the source of the scent. Humans, on the other hand, often smell from a distance. To improve your sense of smell, bring your nose closer to the ground, surfaces, objects, and even the food in your hand.
2. **Sniff Intentionally**: Smelling occurs near the bridge of our noses in a small area called the olfactory epithelium. When we sniff, odor molecules are drawn into our nostrils and reach this tissue, where they interact with our scent receptors. A few sharp sniffs will ensure that more air reaches these receptors, allowing you to detect smells more effectively.
3. **Focus on the Smell**: Many smells pass by unnoticed. By consciously identifying what you’re smelling and trying to describe it, you can expand your vocabulary of scents. When an odor molecule binds to a receptor, it sends a signal to the brain, where it is processed alongside taste, memory, and emotions. Research shows that spending extra time focusing on scents can change how experienced smellers perceive odors.
To get started, take ingredients from your kitchen, such as spices or fruits (avoiding anything toxic). Close your eyes and have someone bring them close to your nose. Sniff and try to identify the source. Over time, you’ll begin to notice nuances in familiar odors and recognize characteristics of new ones.
While a perfumer may practice these techniques to become an expert, even if you don’t pursue smelling to that level, the simple act of enhancing your sense of smell can significantly change how you experience your daily life.
