Yes, it's normal and common to develop strong attachments, even "addictions," to specific smells because scent is directly linked to the brain's emotional and memory centers, triggering pleasure, comfort, or identity, often through dopamine release, but if a smell compulsion becomes distressing or interferes with life, it could be linked to conditions like OCD, and a professional should be consulted.
This phenomenon, often described as “perfume addiction” or a “fragrance obsession,” is deeply rooted in the psychology of scent, which connects smell to emotion, memory, and attraction. Let's explore why we love certain scents, why the more we smell them, the more we get addicted to them.
Your reactions to smells can be influenced by psychological factors and the compatibility of body scents with others. Furthermore, your liking for certain scents and smells can often be linked to past experiences. Memories associated with specific fragrances can shape your preferences.
Desiderosmia was defined by Hansen et al2 As the excessive desire to smell certain odors which develop along with iron deficiency, such as that observed in three cases of pica recorded in 2017. This condition was successfully treated with iron supplementation.
Increased odor sensitivity was found in medication-naïve children with ADHD, but not in adult ADHD, which might be due to a dopaminergic dysregulation presumed to underlie this disorder. Taste sensitivity, in particular bitter sensitivity as a hereditary trait, also might be altered in ADHD.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
For people with autism, this sense can be heightened and more sensitive than for those who do not have autism. They may experience strong reactions to certain smells, which can significantly affect their behavior and well-being.
They also have an unusual sniff pattern called “aberrant sniffing.” Those with autism will generally sniff deeply no matter what scent they are smelling. Whether inhaling the sweet aroma of fresh baked cookies or inhaling the stench of a skunk, their bodies will breathe in with the same intensity.
The hardest smells to get rid of are often deeply embedded, like skunk spray, cigarette smoke, pet urine, mold/mildew, and fire/water damage odors, because they permeate porous materials (carpets, upholstery, drywall, synthetic fabrics) and can get into HVAC systems, requiring professional cleaning or specialized ozone treatments to neutralize the odor molecules themselves, not just mask them.
Kyle is experiencing olfactory reference syndrome (ORS), an underrecognized disorder characterized by preoccupation with the false belief that one emits a foul, unpleasant, or offensive body odor. This preoccupation causes significant distress or impairment in functioning (for example, avoidance of social situations).
8 of the Rarest Fragrances and Ingredients You Need to Try
The characteristic human axillary odor is formed by bacterial action on odor precursors that originate from apocrine sweat glands. Caucasians and Africans possess a strong axillary odor ,whereas many Asians have only a faint acidic odor.
The 30-50-20 perfume rule is a guideline for blending essential oils, suggesting a ratio of 30% top notes, 50% middle (heart) notes, and 20% base notes to create a balanced fragrance, where top notes provide the initial scent, middle notes form the core, and base notes offer depth and longevity. For a 10-drop blend, this translates to 3 drops of top, 5 drops of middle, and 2 drops of base notes, helping DIY perfumers achieve a harmonious scent profile before maturing the blend.
While scientific studies suggest men may subconsciously respond to ovulation odors, there's no definitive evidence that they can actively “smell” ovulation in the way they detect a perfume or food scent. Some men claim to notice changes in their partner's scent during ovulation or menstruation.
Olfactory reference syndrome (ORS), also known as olfactory reference disorder, is an underrecognized and often severe condition that has similarities to obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD).
Nonenal® (also known as 2-Nonenal) is a naturally occurring compound responsible for the distinct odor associated with aging. It typically appears after age 40, becoming more noticeable in both men and women.
Odor characterization
These classes are: 1) ethereal, 2) camphoraceous, 3) musky, 4) floral, 5) minty, 6) pungent, and 7) putrid.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Hand flapping is one of the most recognizable hand posturing behaviors seen in individuals with autism. It involves rapid and repetitive movements of the hands, typically with the fingers extended and the wrists flexed.
Symptoms of High-Functioning Autism
Difficulty with Social Interaction: Individuals with high-functioning autism may struggle to understand social norms, make eye contact, initiate or maintain conversations, and interpret nonverbal cues such as facial expressions or body language.
Over sensitive
Everyday smells, such as spicy foods, scented shampoos or petrol, may overwhelm an autistic person and they may refuse to eat those foods or go to certain places. Some smells can be so overwhelming that they may display unusual behaviours to avoid these smells.
Interoception and Autism
This means we might have difficulty accurately perceiving our internal body signals, we may over-feel these signals or simply have difficulty differentiating between body signals and emotional signals, for example, struggling to discern if our discomfort is due to hunger or anxiety.
