Osaka University scientists in Japan have developed an AI model that accurately predicts biological age using a blood test.
The model analyzes 22 key steroid hormones and their interactions to assess how well a person's body has aged, rather than just counting years. Researchers found that elevated cortisol levels, linked to stress, significantly increased biological age.
This AI-powered system could lead to personalized health monitoring, early disease detection, and tailored wellness programs to slow down aging.
The study, published in Science Advances, marks a step toward preventive healthcare by assessing an individual's 'aging speed'.
