Things You Didn’t Know About the Incredible Sense of Smell

1. Your Nose is Constantly Renewing Itself

Did you know that your sense of smell cells are renewed every 28 days? That means you get a brand new “nose” every four weeks! You can smell as fresh as a daisy every month, thanks to this incredible process of regeneration.

2. Smell and Emotion are Closely Linked

Studies indicate that approximately 75% of emotions are influenced by scent, which plays a key role in triggering feelings of pleasure, well-being, emotional responses, and memory. This is why certain scents can evoke such strong reactions, like the nostalgic memories triggered by the smell of Crayola crayons.

3. Your Nose Can Get Bored

The sense of smell gets bored easily. When you first enter a bakery or a florist, you’re very aware of the aroma, but by the time you reach the checkout, you’ll no longer be able to detect the different scents around you.

4. Smell Develops Before Birth

The sense of smell is the first of all our senses to develop, emerging earlier than sight, taste, touch, and hearing. Even before we’re born, our sense of smell is fully formed and functioning.

5. Women Have a Stronger Sense of Smell

Women’s sense of smell is much stronger than men’s. It’s even heightened during the first half of the menstrual cycle, reaching its peak when a woman is most fertile.

6. Smell Sense Declines with Age

The sense of smell peaks when we’re in our late teens and begins a gradual decline over time. People who have an impaired ability to perceive smells and flavors may be less inclined to follow a nutritious diet.

7. Smell is Affected by Moisture and Exercise

You tend to smell things more easily in spring and summer because of the increased moisture in the air. The sense of smell is also stronger after exercise, which increases the moisture in the nasal passage.

8. Animals Have Incredible Olfactory Abilities

Humans have 5-6 million odor-detecting cells, but that’s nothing compared to the animal kingdom. Rabbits have 100 million, and dogs have 220 million!

9. Sweat as a Unique ID

Forget fingerprints or CCTV; perspiration could be a big thing for crime-busting in the future. Israeli chemists suggest that factors such as the food we eat, medications we take, gender and even our state of mind contribute to the uniqueness of each person’s sweat.

10. Animals Have Favorite Smells, Too

Just like humans, animals have their own favorite scents. Cats like the smell of valerian, lions prefer a mint smell, and camels enjoy the aroma of tobacco.

11. Experiencing History Through Smell

It’s not enough now to go to museums to see the past come to life; you have to smell it too. At the Jorvik Viking Centre, an authentic Viking-era stench is pumped inside to provide visitors with a true simulation of the historical smells. The museum attracts more than 14 million visitors a year who visit to experience smells such as a Viking toilet and village.

12. The Incredible Power of the Human Nose

The human brain can process approximately 10,000 different smells within an area as small as a postage stamp, each one capable of triggering a distinct neural response.

13. The Joy of New Smells

The smell of a new leather jacket or pair of shoes makes everyone happy, but a new car’s scent is the best of all. An artificial “new car smell” is sprayed inside cars to recreate that classic aroma, which can last for up to six weeks.

14. Smell Shuts Down During Sleep

As it turns out, the phrase “wake up and smell the coffee” is more true than you might imagine. When you’re asleep, your sense of smell shuts down, and you can only smell the coffee after you’ve woken up.

15. Smell is Key to Flavor

Your sense of smell accounts for 75-95% of the impact a flavor has. Without the ability to distinguish between the smell of onion and potato, it would be challenging to differentiate them. 

16. Smell in Sports

Sports can also use the power of smell. During baseball’s World Series in 2009, the Tampa Bay Rays ditched stale hot dogs and beer in favor of a scent dubbed “citrus burst” to flood the stadium.

17. Anosmia: The Inability to Smell

People who cannot smell have a condition called anosmia, which can have a significant impact on their quality of life.

18. Signature Scents in the Hospitality Industry

Hotel chains around the world have devised their own signature aromas, from the fig, clove, and jasmine scent of Sheratons to the white tea aroma of Westin lobbies.

19. Smell and Attraction

Our sense of smell plays a significant role in determining who we find attractive. In one study, a selection of women were more attracted to the bodily scents of men who had a different type of gene section.

20. The Struggle of Cacosmia

Spare a thought for the poor people who suffer from cacosmia, a condition where even the most pleasant scents, like fresh flowers, are perceived as revolting or vomit-inducing.
