A recent study suggests plant-based diets can boost attractiveness by improving facial color through carotenoids, enhancing body odor, and aiding favorable body composition, framing vegan eating as a vanity-forward angle to encourage more people to switch from meat.
As people age, changes in skin lipids cause more of the chemical 2-nonenal to form when oils oxidize, creating a perceptible scent often labeled as 'old person smell.' The amount varies by genetics, skin microbiome, hygiene, and environment, and it appears gradually rather than suddenly (some data show emergence around age 40). Studies even suggest the odor is not necessarily unpleasant, and while you can reduce its presence with regular washing and by minimizing oxidative stress through diet, there is no guaranteed way to stop it, and no strong evidence that specialized products dramatically neutralize it.
A viral TikTok trend called 'pheromone-maxxing' has men skipping showers and deodorant before dates to rely on natural body odor for attraction. While linked to the looksmaxxing movement, scientific evidence for human pheromones is inconclusive, with studies showing mixed results and no reliable, consistent behavioral effects, leaving the dating claims unproven despite online buzz and media discussion.
Jerry O’Connell revealed on the Thanks Dad podcast that Rebecca Romijn’s underarm crystals don’t cure her body odor, and he openly says he doesn’t mind—in fact, he kind of likes the smell as a sign they’re alive. The couple, married since 2007, share two kids.
Researchers confirm the so-called 'old person smell' is real and rooted in 2-nonenal, an aldehyde whose production increases with age—typically after 40 and more noticeable in the 50s and beyond. The scent varies by genetics, skin type, lifestyle, and environment, and it lingers on skin and fabrics, not easily washed away. While no proven cure exists, dermatologists suggest antioxidant-based cleansers and products that bind aldehydes, along with good skincare and laundering practices to minimize it. The smell is subjective and may be perceived differently, and aging should be viewed as a natural process rather than a sign of poor hygiene.
The so-called 'old person smell' is real and stems from the aging skin producing more of the aldehyde 2-nonenal, a change driven by factors like reduced antioxidant defenses, altered sebum, and increased environmental damage. Production typically rises after age 40 and varies by genetics, skin type, and lifestyle; some people may not smell it themselves due to olfactory adaptation. There’s no proven cure, but skincare with antioxidants, laundering practices, and certain odor-binding agents may help reduce persistence, with research exploring future approaches such as tannin-containing soaps and eggplant extracts.
The article discusses various personal relationship issues, including a man's insecurity about post-gym body odor that his partner enjoys, a woman's struggle to stay attracted to her aging husband, and a long-term couple facing sexual and emotional disconnection due to aging and health issues. The advice emphasizes understanding and accepting natural body odors, exploring new intimacy strategies, and considering therapy or open communication to address these challenges.
Certain foods like seafood, cruciferous vegetables, spicy foods, and red meat can influence body odor due to their sulfur compounds and other metabolites. Making dietary adjustments, maintaining good hygiene, and staying hydrated can help reduce unpleasant smells, though individual responses vary based on genetics.
A reader asks if using milk of magnesia as a deodorant could harm the kidneys, but the topic has not been adequately studied. Another reader's uncle developed a severe vitamin B12 deficiency after taking omeprazole for years, which hindered his ability to absorb the vitamin. Additionally, a reader found success in treating what was assumed to be nail fungus with over-the-counter antibiotic cream.
Humans have a sense of smell that is comparable to other animals, with roughly 400 different smell receptors capable of detecting over 1 trillion scents. However, we become desensitized to our own scent over time, a process known as odor fatigue. Our ability to detect our own smell can be heightened in certain situations, such as after eating garlic or experiencing stress. Changes in body odor can also be indicative of various illnesses. Our scent is linked to our social relationships, as we use it to assess others and often prefer those who smell like us. Despite its importance, smell has received less attention compared to other senses, but the COVID-19 pandemic has sparked renewed interest in the subject.
Sweat is a fascinating bodily function that humans excel at, with 10 times as many sweat glands as chimpanzees. Sweat can reveal a lot about our bodies, including the presence of substances like caffeine and alcohol. Men and women sweat similar amounts, but a new study suggests that gender can be distinguished by odor alone. Armpit sweat is different from sweat elsewhere on the body, and body odor is created through the interaction of specific skin bacteria and sweat. While antiperspirant deodorants have not changed much in over a century, there are alternative options being explored, such as probiotic deodorants. Artificial sweat is used in various industries for testing purposes. The cause of the historical "sweating sickness" remains a mystery. Sweating does not detoxify the body, and in space, sweat does not evaporate. Fearful sweat has a different chemical composition, and women and dogs can detect it. Early research suggests that sniffing sweat from strangers may help alleviate social anxiety.
Contrary to popular belief, stinky sweat may actually serve as a positive signal. While most people try to eliminate body odor, research suggests that the smell of sweat could indicate certain health benefits. The distinct odor may be a sign of a healthy immune system and could potentially help in attracting mates.
Researchers at Virginia Tech found that certain soap scents can attract or repel mosquitoes. They tested four different soaps on volunteers and found that over 60% of the detectable scent after bathing is attributable to soap. Mosquitoes were then let loose in a mesh cage with two cups inside, one with unwashed scent and the other with washed scent. The researchers found that three of the four soaps made the people more attractive to mosquitoes, and only one made them less. All of the soaps the mosquitoes liked had a fruity or flowery scent. The one that worked as a repellent was coconut scented.
Mosquitoes are attracted to certain human scents, body heat, pregnancy, alcohol consumption, and certain colors. To prevent mosquito bites, use insect repellent, wear long sleeves and pants, and use screens in windows and doors. DEET is an effective ingredient in mosquito repellents. To treat mosquito bites, apply ice, baking soda paste, toothpaste, or anti-itch cream. Scratching a mosquito bite may increase the chance of getting a skin infection.
Mosquito bites itch because the mosquito injects saliva that triggers histamine production, causing inflammation and swelling. Mosquitoes are attracted to carbon dioxide, making some people more prone to bites. Mosquitoes can transmit life-threatening diseases, but the US is not an active transmission area. To prevent mosquito bites, use preventative measures such as vaccines, repellent, and appropriate clothing. Scratching mosquito bites can break the skin barrier and increase the risk of infection, so it's recommended to use ice cubes or creams instead. Floral-scented soaps may attract mosquitoes.
