The “elderly smell” is a body odor that many people associate with old age. In reality, it is not unpleasant in itself, but rather a natural change in the body that occurs with age. Its technical name is 2-nonenal, a chemical compound that increases with age.
At what age does the “old age smell” begin?
Although we generally associate it with people over 70, studies indicate that it can become noticeable as early as 40 or 50 years old. From that age onwards, the body begins to produce more 2-nonenal, which is released through the skin.
Factors that influence the appearance of “elderly odor”:
Hormonal changes
; Oxidation of fatty acids in the skin;
Decreased cell renewal
; Diet high in fat or low in antioxidants;
Lack of ventilation in clothing or enclosed spaces.
Main causes of “elderly odor”:
1. Production of 2-nonenal.
This substance is generated when unsaturated lipids in the skin oxidize. This compound has an aroma similar to damp cardboard or rancid oil.
