Do some people smell better than others?

Yes, some people have a significantly better sense of smell (olfactory acuity) than others due to a mix of genetics, brain structure, health, age, and environmental factors like pollution, leading to conditions like hyperosmia (super smellers) or even variations in detecting specific scents, with women generally outsmelling men and sensitivities changing with pregnancy.

Do some people have good body odor?

The odor can be bad, good or have no smell at all. Factors like the foods you eat, hormones or medications can affect body odor.

What ethnicity has the least body odor?

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.

Who has the no body odor gene?

The gene itself exists in everyone, but the inactive variant (linked to lower odor production) is most common in the East Asian community. ¹ In fact, many people of East Asian descent naturally produce less underarm odor because their sweat contains fewer odor-forming compounds.

Are some people naturally more smelly?

Researchers believe that a particular group of genes, the major histocompatibility complex, play a large role in scent production. These genes are involved in the body's immune response and are believed to influence body odor by encoding the production of specific proteins and chemicals.

What Your Smell Says About You

What is the old lady's smell called?

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.

Do people with ADHD have a strong sense of smell?

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.

At what age does nonenal smell start?

Nonenal smell, or "old person smell," is linked to the natural aging process and can start appearing around age 40, as the body produces more of the compound 2-nonenal from the oxidation of fatty acids on the skin, a process that increases with age and fewer antioxidants. While it's a normal part of aging, the intensity varies, and factors like diet, hormones, and skin health influence its prominence. 

Which people do not have body odor?

Certain variants in the ABCC11 gene may cause a lack of underarm body odor. This is due to how the gene affects the movement of sweat molecules. ABCC11 AA gene variants are most common among people from East Asia. People with this allele may also have dry earwax.

What body parts have the most odor?

Eccrine glands are all over your body and produce a watery sweat to help cool you down. Apocrine glands, on the other hand, are found in areas like your armpits and groin (areas with a high density of hair follicles). They produce a thicker sweat that bacteria love to break down, leading to stronger odors.

Does wet earwax mean body odor?

Yes, wet earwax (sticky, brownish) is strongly linked to more noticeable body odor because the same gene (ABCC11) that causes wet wax also affects apocrine sweat in the armpits, leading to smelly compounds when bacteria break it down, while dry earwax (flaky) is associated with less odor.
 

Is natural body odor attractive?

Research shows that people often find certain body odors appealing, which may indicate a healthy immune system or genetic diversity. Your sense of smell is finely tuned to detect these pheromones. A pleasant scent can enhance feelings of attraction, while an unpleasant odor may push you away.

What is the natural scent of a woman called?

A woman's natural scent isn't one specific thing but a complex mix from skin bacteria (microbiome) and pheromones, chemicals like estratetraenol and androstenol that might influence mood and attraction, though human pheromones are still debated; scientists identify compounds like geranyl-acetone as part of this unique scent profile. 

Which ethnicity has the least body odor?

Most of the world's population has the gene that codes for the wet-type earwax and average body odor; however, East Asians are more likely to inherit the allele associated with the dry-type earwax and a reduction in body odor.

How do I know if I smell bad to others?

To know if you smell bad, ask a trusted friend for an honest opinion, sniff your own clothes (especially after wearing) or skin (like your armpit/wrist), check for stains on clothes, and notice if people keep their distance or make comments. Since nose blindness makes self-detection hard, relying on trusted feedback or specific smell tests on fabric/skin after showering is key. 

Why is there no deodorant in Korea?

What's with the lack of quality deodorant in Korea? Basically, most Koreans don't actually need deodorant. Several years ago, scientists discovered a gene that was dubbed “ABCC11”. The team who discovered the gene found that it was a key determinant in whether a person will produce dry or wet earwax.

What deficiency causes bad body odor?

Body odor can stem from deficiencies in nutrients like zinc or genetic disorders affecting metabolism, such as Trimethylaminuria (TMAU) causing a fishy smell, or Phenylketonuria (PKU) leading to a musty odor, both related to enzyme deficiencies that prevent proper breakdown of compounds like trimethylamine or phenylalanine. A deficiency in Biotin (Vitamin B7) can also impact metabolism and potentially alter body odor. 

What does diabetic sweat smell like?

Diabetic sweat often smells sweet, fruity, or like nail polish remover (acetone) due to ketones, a byproduct of fat burning when the body lacks insulin, indicating uncontrolled blood sugar, especially in conditions like diabetic ketoacidosis (DKA), a serious medical emergency. While not always detectable, this scent can signal high ketone levels, requiring immediate medical attention if accompanied by thirst, frequent urination, or weakness. 

What age is body odor the worst?

Usually, this happens when females are 8–13 years old, and males are 9–14. But it can also be normal to start puberty earlier or later. Bathing every day, especially after a lot of sweating or in hot weather, can help with body odor. So can wearing clean clothes, underwear, and socks each day.

Can showering remove nonenal odor?

Daily bathing helps eliminate the fatty acids and bacteria that lead to nonenal. Use lukewarm water and the best soap for nonenal odor, like those with persimmon extract, to break down the compounds causing the scent.

What two tastes do elderly lose first?

Remaining taste buds shrink as we get older too, resulting in diminished sense of taste. Typically, seniors notice this loss of taste with salty or sweet foods first.

What is the 2 minute rule for ADHD?

The ADHD "2-Minute Rule" is a productivity hack where you do any task that takes two minutes or less immediately, preventing small things from piling up and becoming overwhelming. While great for momentum, it needs modification for ADHD; a related idea is the "2-Minute Launch," where you commit to starting a bigger task for just two minutes to overcome inertia, building momentum to continue, though you must watch for getting lost in "rabbit holes" or task switching issues common with ADHD. 

Do people with anxiety smell?

It doesn't happen to everyone, but some people find that their body odor appears to significantly change when they have anxiety. This change may be subtle or may occur to a degree that they feel more anxious in social situations due to fear of developing a noticeable odor.

What is the 30% rule in ADHD?

The ADHD "30% Rule" is a guideline suggesting that executive functioning (self-regulation, planning, impulse control) in individuals with ADHD develops about 30% slower than in neurotypical peers, meaning a younger developmental age. For example, a 12-year-old with ADHD might have the executive skills of a 9-year-old, helping parents and educators set realistic expectations and understand behavioral differences, not a lack of intelligence. This concept, popularized by Dr. Russell Barkley, is a helpful tool, not a strict law, to foster empathy and appropriate support.
