Does your house smell without you knowing it? Nose Blind!

Does Your House Smell

Since the outbreak of the epidemic, many of us have transformed our houses into workplaces, classrooms, gymnasium, day-care facilities, and other spaces, bringing with us our constant presence—and the body odours that accompany it. 

We’ve also included more odour-producing activities, such as cooking food take-out indoors every night and regularly sweating via squats or yoga stretches. As a result, your home is likely to have acquired new or stronger odours, but if you’ve grown accustomed to them, you may not have been able to perceive them owing to a condition known as nose blindness.

What Is Nose Blindness?

Some smells are just no longer detectable when you are nose blind. This is especially true if you are unable to detect odours in a location where you invest a substantial period of time. Nose blindness, despite its name, is not completely unavoidable and is not a medical condition. It’s not the same as eliminating your smell completely.

Instead, most people are only sensitive to certain smells or combinations of odours. Moreover, the majority of people have some degree of nose blindness. This phenomenon is a natural component of how our minds work, despite the fact that it can be annoying.

It’s vital to distinguish nose blindness from anosmia, a disease in which your general sense of smell is substantially diminished or absent. An infection, damage, or other reasons can cause anosmia, which is different from nose blindness. 

Causes of nose blindness

Your senses feed your brain a great deal of information about your environment each day. Your brain could soon become overwhelmed if you don’t have a mechanism to sift through all of this entering input adequately. Biological adaptations such as nose blindness play a role in this. Nose blindness can help prevent sensory overload of your perceptions by lowering your awareness of odours that you’re subjected to regularly or continually.

Additionally, by reducing your ability to identify regular smells surrounding you, it will be simpler for you to notice something unusual that deserves your attention. The fragrance of bread toasting in your toaster or a gas leak in your home are both examples of this.

The actual biological aspects of the nose blindness’ process are unclear. Nevertheless, we have a basic idea of what is going on in your head at the time. An odorant (aroma particle) connects to a receptor on a unique sort of sensory nerve that recognizes odours when you breathe it. Your brain receives an electronic current from this nerve cell. Your brain then processes the fragrance.

The nerve cell gradually ceases transmitting its electronic current to your brain after repeated or prolonged activation by a specific odorant. As a consequence, you are unable to detect the aroma. In essence, you lose your sense of smell.

What Are the Signs That You’re Nose Blind?

One of the difficulties with nose blindness is recognizing it. It’s difficult to say for sure if there was anything you’re missing because you can’t smell the odour. If you come home from a trip and your house smells musty or mouldy, you may have nose blindness. Of course, it’s conceivable that your house smells completely different after your vacation. The most likely answer is that you’ll be nose blind and have always been aware of the stench.

Consider seeking the support of friends or family who may not live in your house if you are worried about nose blindness. Inquire if anything stinks musty or nasty. Please remember that most individuals attempt to avoid remarking on the scents of other people’s houses. It’s a good idea to clarify the scenario ahead of time and make it very clear that it’s fine to declare something smells. You could also realize that your house smells a little different. If you can sense the odour, you may anticipate any visitors to notice it more strongly.

How to Lower the Risk of Nose Blindness?

There are a few things you can do to minimize nose blindness and improve your perception of smell in your house. 

Abandon the area

The most straightforward technique to eliminate nose blindness in your house or any location where you spend lots of time is to depart for a while and then come back. You’ve probably noticed this if you’ve ever left your house for an extended length of time and then returned to find that it smelled differently than it was before you left.

Working Out

It may sound unusual, but working up a sweat might boost your sense of smell. In fact, according to a 2014 study, older persons who exercised on a regular basis used to have a lower likelihood of experiencing a loss of smell. It’s unclear how exercising impacts your sense of smell. Strenuous exercise, such as cardio, does, however, boost the circulation of blood, including in the nose. This may assist you in detecting odours.

Recognise it

While we don’t encourage getting too worked up about the smell of your house, being conscious of it can help prevent nose blindness. The explanation for this is that your brain pays closer attention to something when you intentionally try thinking about it. As a result, you may become more susceptible to odours you previously overlooked.


Interestingly, coffee has been described as a possible palette cleanser for the nose. According to one theory, some smells contained in coffee may have qualities that cause other odorants to be displaced from scent-detecting nerve fibres.

Final Verdict

Nose blindness is a biological response that makes it difficult to identify or differentiate common odours in the environment. Your nose & brain are better able to identify odd or possibly toxic odours by shutting out common fragrances.

While nose blindness makes it harder to detect aromas in your home, there are several methods for preventing common household odours. Cleaning regularly, replacing your HVAC filters, and allowing fresh air into your home can all assist in preventing odours.
