Introduction
Under normal circumstances, body odor (bromhidrosis) will not spontaneously and completely disappear at a specific age. It is important to maintain good hygiene by keeping the underarm area clean, showering regularly, and changing into loose, breathable cotton clothing frequently to reduce bacterial growth. After sweating, promptly wipe the area to avoid prolonged sweat retention. Additionally, reduce consumption of spicy and pungent foods such as chili peppers and garlic.
Generally, body odor will not automatically and completely disappear at a specific age. Detailed analysis is as follows:
Body odor is related to the function of the axillary apocrine glands. Secretion from these glands is influenced by genetic factors and remains active after puberty, regulated by hormone levels. The sweat secreted by these glands is broken down by bacteria, producing a distinctive odor. With aging, apocrine gland function may gradually weaken due to hormonal changes, and the odor might decrease somewhat. However, the glands themselves will not completely stop secreting, nor will they suddenly lose function at a fixed age. Therefore, body odor will not automatically and completely disappear at a specific age.
In daily life, it is important to maintain underarm cleanliness by showering frequently and changing into clean, breathable cotton clothing regularly to reduce bacterial growth. Sweat should be wiped off promptly to avoid prolonged accumulation. Diet-wise, consumption of spicy and stimulating foods, such as chili peppers and garlic, should be reduced, as these foods may exacerbate sweat secretion and odor. If the odor affects your daily life, you may consult a dermatologist and choose an appropriate method of improvement according to your individual situation.
