The Science of Smell: Nose Blindness & How to Mitigate It

Oh, how we love to smell! However, we may not even notice our own smell whether it’s good or bad. Your nose, just like the rest of your body, can become tired too! Now, we’re not talking about that sore feeling after your workout or tension headaches from your job. We’re instead talking about how your nose becomes fatigued. 

The Science of Smell

Your nose can forget or become used to the scent around you. This is known as olfactory fatigue, nose blindness, or olfactory adaptation. Who knew your nose can be considered as blind! However, this is only temporary blindness after prolonged exposure. Thus, there is this assumption that we are unable to smell our own scent. Yet, other people can smell our scent. This is due to the prolonged exposure of your own scent on your skin. Another example could be your house smell. Most of us know, when we walk into our best friend’s house, there is that distinct smell. But have you ever experienced the normal smell of your own house? Most likely not. This is because you live there, and your nose becomes used to the scent of your home.


But why does your nose become used to the scent or smell around you? This is due to your neural or sensory adaptation. The body or nose becomes desensitized to stimuli. Your body does this to prevent the overloading of your nervous system from various aspects surrounding you. Through this protection, your body allows other stimuli to come in which are new or out of the ordinary. For instance, if you are making the food you can become used to the smell which encompasses your home. Though, your friend or family may walk in and tell you how great it smells even though you can no longer smell the meal. In this situation, your body is protecting itself from an overabundance of senses. Yet, your friend or family member walks into the room and they are experiencing new stimuli. If your company stays for a long time, their body will eventually block out the scent as well.

Enhance the scent

Unfortunately, perfumes have a similar effect on your nose. By the end of the day, you may think your perfume was washed off. This might be partially true, but it is also due to your olfactory system becoming accustomed to the scent. The science of perfume is pretty amazing!

You are probably wondering what this has to do with our P&J Trading Fragrance Oils. Fragrance oils were developed to stimulate our noses or olfactory system. However, you just learned how our bodies become used to the stimuli or perfumes around us. Thus, we want to highlight a few ways you can keep our fragrances prevalent on your skin and in your home! One way to keep your favorite P&J fragrance on your skin is to add carrier oil. A carrier oil can consist but is not limited to coconut oil, almond oil, or avocado oil. Simply take the oil and stir in a few drops of your favorite fragrance. Once you apply, the scent should last longer and stimulate your olfactory system. Another way to keep your hour and nose happy is by placing a P&J fragrance in a diffuser with alcohol. The alcohol will carry the fragrance further and disperse around your home.
