The case of Maria Brañas Morera, who reached the age of 117, became the subject of a large-scale scientific study that challenged traditional notions of aging. Scientists discovered that her body exhibited unique characteristics that allowed her to maintain health into old age.
A comprehensive analysis of biological samples collected a year before her death revealed several key factors. Although chromosomal telomeres were significantly shortened, which typically indicates cellular aging, this feature potentially reduced cancer risk. Her immune system remained functional, and her genetic profile contained protective gene variants that protected the cardiovascular and nervous systems.
A key role was played by low-grade inflammation and the preservation of a "young" gut microbiome, dominated by bifidobacteria. The researchers note that Maria's healthy lifestyle, including a balanced diet and social activity, combined with favorable genetics, created unique conditions for exceptional longevity.
It has been previously reported that sleep is a critical component of brain health and cognitive function, not just a period of rest. Furthermore, uncontrolled increases in medication doses can pose serious health risks.
