Adolescence is a time of significant change, not only physically but also chemically. Research published in Communications Chemistry has explored the factors that cause the distinct body odor associated with this stage of development.
While babies have a characteristic baby smell, primary school children do not have a noticeable odor. However, teenagers begin to emit a new type of smell that is different from that of younger children. The increased activity of sebaceous glands and sweat glands during adolescence may contribute to this alteration in smell, potentially due to the increased secretion of sweat and sebum. Specifically, volatile steroids were found in the armpits of teenagers but not in younger children, affecting the smell of underarm sweat.
Further analysis revealed differences in the presence of certain compounds between children under four years old and teenagers between 14 and 18. Teenagers had higher concentrations of carboxylic acids and other compounds that emitted odors described as waxy and reminiscent of goats. On the other hand, compounds with violet and soap scents were found in younger children but not in teenagers.
It’s important to note that this study did not specify whether all individuals in each age group exhibited the same compounds in their armpits. Overall, the research sheds light on the chemical changes that contribute to the distinct body odor associated with adolescence.
