Study reveals biological age differs from chronological age

A new study from Osaka University has revealed that a person's actual age can differ from their age in years. Researchers, Dr. Qiuyi Wang and Dr. Zi Wang, have developed a method to estimate biological age using steroid hormones found in the bloodstream. The study published in Science Advances used artificial intelligence to analyze blood samples from 148 participants aged 20 to 73. They measured 22 different steroid hormones in each sample, employing advanced techniques to understand aging. The results indicate that people age differently, allowing for better detection of age-related health issues. Cortisol, known as the stress hormone, was identified as a key factor that can accelerate aging. Dr. Wang emphasized that hormones are crucial for maintaining balance in the body and could be used as markers for aging. Professor Toshifumi Takao noted that the research provides clear evidence of stress's effect on biological age. The findings suggest that managing stress may help slow down the aging process.
