How different types of stress affect telomere length and aging | Elissa Epel

Parent Episode: Dr. Elissa Epel on Telomeres and the Role of Stress Biology in Cellular Aging

Toxic stress, which results from prolonged adversity due to physical or emotional abuse, chronic neglect, exposure to violence (especially early in life), and workplace burnout can have long-lasting repercussions on a person's mental and physical health. People who experience toxic stress often develop a profile of perseverative cognition – a prolonged response to stress that manifests as worrying or rumination and is characterized by accelerated biomarkers of aging, shortened telomeres, and inflammation. In this clip, Dr. Elissa Epel describes how stress – and even a pessimistic attitude – can modulate telomere length.
