Study links sleep-disordered breathing to age acceleration

SAN ANTONIO — Increasing severity of sleep-disordered breathing and sleep disruption are associated with epigenetic age acceleration, according to preliminary results of a new study. Results show that each standard deviation increase in the apnea-hypopnea index, a measure of sleep-disordered breathing severity, was associated with the equivalent of 215 days of biological age acceleration. Similarly,…
