The third decade of life is considered a turning point for many people; Not only from a social and occupational point of view, but also from a physiological point of view, the human body undergoes gradual but significant changes in this period of time. These changes, which often begin without obvious symptoms, can lead to a decrease in the quality of life, an increase in the risk of chronic diseases, and a decline in physical performance in the following decades if not paid attention to. Correctly understanding these processes and adopting approaches based on scientific evidence is the first step in maintaining long-term health.
