De ce mirosul unei persoane se schimbă odată cu vârsta? Cum apare „aroma” bătrâneții? Substanța responsabilă • Newsweek România

As people age, their body odor changes due to biochemical alterations in the skin, particularly the production of 2-nonenal, a compound linked to aging. This change is influenced by various factors, including lifestyle, medications, and personal hygiene. While 2-nonenal is a significant contributor, the perception of 'old person smell' is also shaped by memories and cultural associations. To minimize body odor, maintaining good hygiene, washing clothes regularly, and staying hydrated are recommended. Sudden changes in body odor should be discussed with a doctor, as they may indicate underlying health issues.
