Why do Chinese not have body odor?

Many Chinese people, along with other East Asians, have significantly less body odor due to a common genetic mutation in the ABCC11 gene, which results in less odor-causing compounds in their sweat, watery sweat, and dry earwax, a trait linked to evolutionary adaptation, possibly for colder climates, that reduces bacterial breakdown of sweat into smelly byproducts.

What ethnicity has no body odor?

Genetic variants that cause a loss of function of the ABCC11 gene are very common among East Asian ethnicities (80-90% of the population). In other population groups, it is rare to have no body odor. In fact, only around 2% of Caucasians carry the 'no body odor' version of the gene.

What do Chinese people use instead of deodorant?

Used in Southeast Asia for centuries, potassium alum is still sold today worldwide as “deodorant stones” – natural, perfume-free alternatives to commercial deodorants.

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.

Why do some cultures not wear deodorant?

Some cultures don't wear deodorant due to a combination of genetics (like the ABCC11 gene common in East Asians reducing odor), cultural perceptions where sweating is seen as natural or healthy, different hygiene practices, diet influencing smell, and sometimes economic factors or religious beliefs, leading to varying definitions of what constitutes "bad" body odor. 

Why Asians Don't Smell?

Can Jews wear deodorant?

Deodorant merely masks smell and is not medicinal; therefore, it may be used on Shabbos. Stick deodorant should not be used due to the prohibition of smearing.

Do Chinese people need deodorant?

Chinese people, like all people, need to maintain hygiene, but a common genetic variation (ABCC11 gene) in East Asians, including Chinese populations, significantly reduces the bacteria-causing body odor, meaning many don't need strong deodorants, though some still use them for fragrance or cultural reasons. This gene results in less of the apocrine sweat that bacteria feed on, linked to having dry earwax and less axillary odor. 

Do Asians have less body odor?

Yes, many East Asians naturally have significantly less body odor due to a genetic variation in the ABCC11 gene, which affects sweat composition, making it less fatty and thus less appealing to odor-causing bacteria; this gene also determines dry earwax and is common in populations like Koreans, Chinese, and Japanese, leading to lower deodorant use compared to Europeans and Africans. 

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 country uses the most deodorant?

Deodorant Use by Country 2025

• United States. $320M.
• Germany. $264.7M.
• Netherlands. $226.6M.
• United Kingdom. $176.4M.
• France. $162.6M.

How to stop smelling like bo without deodorant?

To get rid of body odor without deodorant, focus on killing odor-causing bacteria with antibacterial soap, benzoyl peroxide wash, or natural options like lemon juice/vinegar, while also keeping skin dry with cornstarch/baking soda and wearing clean, natural fabrics like cotton to manage sweat and bacteria. Shaving your underarms also helps sweat evaporate faster, reducing bacterial growth. 

Which Asians have ABCC11?

The frequency of alleles for dry ear wax is most concentrated in East Asia; most notably China, Japan, Korea, and Mongolia. The allele frequency is highest among the northern Han Chinese and Koreans; followed by Mongols, southern Han Chinese, and Yamato Japanese, respectively.

Which race 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.

Which ethnicity has the most body hair?

Harry Harris, publishing in the British Journal of Dermatology in 1947, wrote Native Americans have the least body hair, Han Chinese people and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair.

Why do Japanese not have body odor?

Between 80 and 95% of East Asians have a dysfunction of the ABCCII gene, which is linked to smelly pits, a number of studies say. And this means their bodies don't release the same acidic odor smell the rest of the population does when exposed to hot temperatures and perspiration.

Is it normal for a girl to smell a little fishy?

Unhealthy Vaginal Odors

If you notice any of these vaginal odors, you may want to contact your gynecologist. Fishy. If you're experiencing a strong vaginal odor that smells like a dead fish, it may be a sign of bacterial vaginosis (BV) or trichomoniasis.

What happens if you never shave your pubic hair as a female?

No Shaving, No Problem

The good news is, if you never shave your pubic hair, nothing drastic happens. Pubic hair grows to a certain length and then stops, so you're not going to end up with a never-ending forest. In fact, going without shaving can reduce the risk of skin irritation, razor bumps, and ingrown hairs.

Do gynecologists prefer shaved?

No, you don't need to shave or wax. However, if there's something going on with your skin, shaving or waxing will make it easier for your physician to evaluate the area.

Do Asians have different earwax?

Yes, people of Asian descent generally have dry, flaky earwax, unlike Caucasians and Africans who typically have wet, sticky earwax, a difference determined by a single gene (ABCC11) linked to ancestry and potentially influenced by past climate adaptations.
 

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.
 

Why is deodorant rare in Korea?

Most Koreans lack the gene that causes the type of sweat responsible for body odor. As a result, underarm odor is uncommon, and deodorant can be difficult to find in local shops and supermarkets.

What is the no body odor gene?

The "no body odor gene" refers to a variant of the ABCC11 gene, most common in East Asians, which stops the production of key odor-causing sweat components, leading to little to no underarm smell and often resulting in dry earwax. When this gene is inactive (AA genotype), sweat molecules can't reach skin bacteria, effectively starving them of the compounds needed to create typical body odor, meaning people with this variant may not need deodorant. 

Do Vietnamese people use deodorant?

This cultural reliance on water and soap, rather than packaged solutions, explains why deodorant usage in Vietnam historically lagged behind other personal care categories like skincare or haircare.

Is there a link between sweat and ethnicity?

It has been found that total numbers of active sweat glands increase in tropical populations compared with people from northern latitudes. 3. 3. It has also been observed that the active sweat glands of Eskimos are fewer than those of Caucasians.
