Elissa Epel is an American health psychologist and professor of psychiatry at the University of California, San Francisco (UCSF), where she directs the Aging, Metabolism, and Emotion Center.
She studies how chronic stress affects the body: hormones, metabolism, eating behaviour and biological ageing.
A well-known study (PNAS, 2004) of mothers caring for a chronically ill child found that those reporting more stress had shorter telomeres, the protective ends of chromosomes.
With Nobel laureate Elizabeth Blackburn she wrote The Telomere Effect (2017), followed by The Stress Prescription (2022), with short daily practices.
She also studies mindfulness, sleep and ‘good’ stress, such as brief physical challenges the body recovers from.
For longevity, her work shows that mental strain leaves measurable biological traces, and that recovery matters as much as the stress itself.
Takeaway: deliberately plan moments of recovery into your day, such as a walk, a breathing exercise or a good night’s sleep.
