Breathing Patterns and the Clock of Our Genes
Ever wondered if the way we breathe could be tied to our biological age? A recent exploration into the world of epigenetics, which studies changes in gene function without altering the DNA sequence, has revealed some fascinating insights. Researchers looked at a marker called GrimAge, which is believed to be a predictor of lifespan and health. They found that certain measures of lung function, specifically the forced expiratory volume in 1 second (FEV1) and the ratio of FEV1 to forced vital capacity (FVC), were negatively associated with GrimAge. In simpler terms, better lung function seemed to be linked to a "younger" biological age. Moreover, this epigenetic age marker also hinted at the future risk of emphysema, a lung condition that causes shortness of breath.
