Lonely days: Linking day-to-day loneliness to biological and functional aging.
Abstract
Lonelier people age more quickly than their less lonely counterparts. Nevertheless, loneliness has been conceptualized as a stable trait rather than a fluctuating experience. The current study examined whether two markers of loneliness in daily life-average daily loneliness and loneliness susceptibility, that is, day-to-day fluctuations with changing circumstances-were associated with poorer biological, phenotypic, and functional aging outcomes.
