Tired telomeres: Poor global sleep quality, perceived stress, and telomere length in immune cell subsets in obese men and women

Peer-Reviewed Scientific Journal:
Brain, Behaviour and Immunity

Size of study:
87 obese men and women

Summary
Poorer global sleep quality as measured using the Pittsburgh Sleep Quality Index predicted shorter telomere length in CD8+ T cells among those with high perceived stress but not in low stress participants. These findings suggest that these is a link between poor sleep quality, stress and immune cell telomere length in obese individuals.
