Body odor evolution beyond hygiene
The article explains that chemical changes within the skin as people age—particularly the increase in a compound called "2-nonenal," produced by the oxidation of fats on the skin’s surface—may account for the different body odors often observed in the elderly. While levels of this compound typically rise during middle age, its impact on odor is not uniform; studies have shown that the body smell of older adults can sometimes be less bothersome than that of middle-aged individuals. Additionally, body odor is influenced by various factors such as diet, medications, lifestyle, and the environment. Currently, there is no available treatment targeting "2-nonenal," but the article recommends maintaining proper hygiene and hydration habits. It also advises consulting a doctor if there is a sudden change in body odor accompanied by other symptoms, as this could indicate an underlying health condition.
