Sleep is the most important period for recovery from daily load. Regular physical activity enhances overall sleep quality, but the effects of acute exercise on sleep are not well defined. In sleep hygiene recommendations, intensive exercising is not suggested within the last 3 h before bed time, but this recommendation has not been adequately tested(More)
Early life stress (ELS) poses a risk for mental disorders and aging-related diseases. Accelerated biological aging, reflected in shorter leukocyte telomere length (LTL), may underlie these risks. We examined whether objectively recorded ELS and retrospectively self-reported traumatic experiences across the lifespan are associated with LTL in later(More)
OBJECTIVE Telomere shortening, a biomarker of cellular aging, has been associated with aging-related diseases. While psychological stress has been implicated in the process of telomere shortening, associations with activity of physiological stress systems have remained elusive. We studied whether leukocyte telomere length (LTL) is associated with(More)
OBJECTIVES Sleep apnea poses an elevated risk for chronic age-related diseases. Leukocyte telomere length (LTL), a biomarker and factor associated with accelerated cellular aging processes, may serve as a novel mechanism underlying these disease risks. We investigated if a history of clinician-diagnosed sleep apnea or primary snoring was associated with LTL(More)
Shorter leukocyte telomere length (LTL) has been linked with mental disorders and with other manifestations of chronic non-communicable diseases. Mental disorders are associated with increased morbidity and premature mortality. It remains unclear if shorter LTL characterizes patients who have been diagnosed with mental disorders in the past, and who have(More)
OBJECTIVE Maternal depressive symptoms during pregnancy are associated with increased risk of psychiatric problems in children. A more precise understanding of the timing of the symptoms during pregnancy and their independence of other prenatal and postnatal factors in predicting child psychopathology risk is needed. We examined whether maternal depressive(More)
OBJECTIVE Personality traits have been associated with cardiometabolic diseases and mental disorders as well as with longevity. However, the underlying mechanisms are not fully understood. Accelerated cellular aging may play a role in this process. We studied whether personality traits in late adulthood, as defined in the five-factor model (FFM), were(More)
