Have you ever walked into your home and been hit with a funky smell, only to realize it’s been lingering for who knows how long? Or have you ever had guests over who politely mention a strange odor that you can’t even detect? You may be suffering from a common condition known as “noseblindness,” where your nose becomes desensitized to the smells around you.
But fear not, there are ways to banish those pesky odors and ensure your home always smells fresh and clean. Keep reading to learn how to fix noseblindness and become the ultimate home odor detective.
What causes noseblindness to house odors?
1. Stimuli receptors
The nose contains two main olfactory systems: the main olfactory system, which detects volatile stimuli, and the accessory olfactory system, which detects fluid-phase stimuli. The vomeronasal organ, located in the vomer, between the nose and the mouth, is responsible for detecting stimuli in the accessory olfactory system.
The sensory receptors in these systems are responsible for detecting different types of odors, including pheromones. However, repeated exposure to certain smells can cause these receptors to become desensitized, leading to noseblindness or the inability to detect certain odors. This is because the brain becomes accustomed to the smell, and the receptors stop sending signals to the brain.
2. Scent receptors
Scent receptors are specialized cells in the nose that detect and transmit information about different smells to the brain. These receptors are located in the olfactory epithelium, a thin layer of tissue in the nasal cavity.
When we inhale, odor molecules enter the nose and bind to the receptors, triggering a series of chemical reactions that generate electrical signals. These signals are then transmitted to the olfactory bulb, where they are processed and interpreted as specific odors.
Noseblindness, or the inability to detect certain odors, can occur when there is a loss of sensory cells in the nose or a decrease in nerve fibers and receptors in the olfactory bulb. This can happen as people age or due to other factors such as illness or injury.
When the number of scent receptors decreases, it becomes more difficult to discriminate between different smells, making it harder to identify specific odors like those found in a house. Additionally, deterioration in the central nervous system’s cognitive processing functions can also contribute to noseblindness by impairing the brain’s ability to interpret and distinguish between different odor signals.
3. Response to odors
While the research provided does not directly address the topic of “noseblindness,” it can still provide some insights on how our sense of smell works. Noseblindness refers to the phenomenon where we become desensitized to certain smells in our environment, making it difficult for us to detect them.
This can be caused by sensory adaptation, where our sense of smell adjusts to constant odors, or exposure to strong and persistent smells. Common household smells that we may become noseblind to include pet odors, cooking smells, and cigarette smoke.
To combat noseblindness, it is important to regularly air out our homes, clean surfaces and fabrics, and use air-purifying devices. Additionally, taking breaks from exposure to certain odors can help reset our sense of smell and improve our ability to detect them.
4. Memory formation
The formation of memory plays a crucial role in noseblindness for house odors. Research suggests that the release of nitric oxide (NO) in brain regions such as the hippocampus can mediate synaptic plasticity changes and influence long-term potentiation (LTP) and memory formation.
In sheep, the increased sensitivity of mitral-to-granule cell synapses that results from learning the odors of their lambs might involve potentiation of glutamate release by NO through modulation of cGMP. In the olfactory bulb, NO is released by glutamate acting on both NMDA and AMPA receptors, which are present on the main olfactory bulb mitral and granule cells.
The activation of both receptor types is required for the formation of pheromonal olfactory memory. Therefore, memory formation can contribute to noseblindness by making individuals less sensitive to the odors of their house as they become more familiar with them over time.
5. Exposure to odors
Exposure to odors can cause noseblindness, which is a decreased ability to detect odors after prolonged exposure. This can lead to a lack of awareness of unpleasant odors in the home. One way to prevent noseblindness is to regularly air out the house and clean surfaces where odors can accumulate, such as carpets and upholstery.
Using air fresheners or odor-absorbing products can also help. Additionally, regularly switching up the scents in the home can prevent habituation to a particular odor. It’s important to note that noseblindness can occur in both young and older adults, but it is fully reversible after a week of exposure to different odors. By taking these steps, you can keep your home smelling fresh and prevent noseblindness.
What are the signs and symptoms of noseblindness to house odors?
1. Difficulty identifying house odors
People with anosmia, also known as noseblindness, have difficulty identifying house odors because their sense of smell is impaired or completely absent. The causes of anosmia can vary and include genetic disorders, infections, head injuries, and sinonasal disorders.
Treatment options depend on the underlying cause and may include smell training, zinc supplements, corticosteroid drugs, or surgery. However, some cases of anosmia may resolve spontaneously without treatment.
One of the challenges for people living with anosmia is identifying and distinguishing the condition, which can lead to difficulty finding appropriate care. T
2. Difficulty identifying the source of house odors
Individuals experiencing noseblindness, or anosmia, may have difficulty identifying the source of house odors. This is because they cannot rely on their sense of smell to detect and distinguish different scents.
Additionally, some individuals may have acclimated to certain smells, making them difficult to detect. This can be especially problematic if the odor is a result of a dangerous substance, such as carbon monoxide.
3. Lack of reaction to house odors
Noseblindness is a common condition where a person becomes accustomed to certain smells in their environment and no longer notices them. This can be a problem when it comes to household odors, as some of them can be a sign of indoor air hazards.
For example, stale or stuffy air, abnormal and noticeable odors, and a clear lack of air movement can all be indicators that there is a problem with the air quality in the home. Some common household smells that noseblindness can mask include cigarette smoke, cooking odors, pet odors, and mold and mildew.
If these smells are not detected, it can lead to health problems such as respiratory issues, headaches, and allergies. It is important to regularly check and maintain the heating and air conditioning systems, remove water-damaged materials, and ensure proper ventilation to prevent noseblindness and potential health hazards.
4. Increased stress or anxiety due to house odors
While there is limited research on the direct effects of specific odors on human stress, studies on animals suggest that certain odors, such as predator odors, can activate the stress response and lead to post-traumatic stress disorder. In daily life, being noseblind to unpleasant house odors, such as pet odors or cooking smells, can lead to increased stress or anxiety for individuals who are sensitive to these smells. This can manifest as discomfort, agitation, or even avoidance of certain areas or activities in the home.
How to know what your house smells like

FAQ
What is “noseblindness”?
“Noseblindness” or olfactory adaptation is a natural process in which our nose detects an odor, determines it’s not a threat, and then shuts down the receptors for that smell. This is useful when there are changes in our environment like when something starts to go bad or when there’s a sudden odor.
However, this process becomes less helpful when it comes to lingering smells in our homes. As a result, we may not be able to detect a funky smell in our homes because our nose has become accustomed to it.
How do I find out why my house smells?
To identify the source of unpleasant odors in your home, it is important to systematically go through each room and try to pinpoint the source. Start by checking for any obvious sources such as dirty dishes, trash, or pet messes.
If these are not the cause, move on to less obvious sources such as mold or mildew, dirty carpets or furniture, or even the HVAC system. It may also be helpful to open windows and doors to air out the space.
Once the source is identified, take appropriate action to eliminate the odor, such as cleaning or repairing the source, using air fresheners or odor eliminators, or seeking professional help.
Can you smell your own house smell?
Yes, it is possible to become accustomed to the smell of our own homes, including any odors left behind by our pets. This is because our brains filter out constant stimuli, such as the scent of our own homes. However, guests or prospective buyers who are not used to the smell of our homes may notice these odors.
This is similar to how we may not notice the smell of our own perfume or cologne after a while, but others around us can still smell it.
How do I find my own smell?
Here are some steps to finding your own odor-eliminator scent:
- Consider what scents you typically enjoy in your daily life, such as perfumes or candles.
- Take note of any smells that you are particularly sensitive to and avoid those in your odor-eliminator search.
- Try out a variety of scents to see what you like best. Look for samples or travel-sized options to test before committing to a full-size product.
- Keep in mind the area where you will be using the odor eliminator. For example, a warm and woodsy scent may be more appropriate for a living room while a light citrusy blend may work well in a bathroom.
- Don’t be afraid to try unscented options if you prefer to have no added fragrance.
How do I know if my room stinks?
If you suspect that your room has an unpleasant odor, there are several ways to identify the source of the smell. The first step is to identify the type of odor. If it smells musty, it may be caused by mold or mildew. If it smells like rotten eggs, it may be caused by a gas leak. If it smells like cigarette smoke, it may be caused by smoking or exposure to secondhand smoke.
