• Stress, Immunity, and Illness: Insights from experimental common cold studies on holiday susceptibility
    Dec 17 2024

    Can you believe it's almost the end of 2024?! Join me for a conversation with Dr. Aric Prather about stress, sleep, and social experiences at the holidays + what we know about links between those and our susceptibility to infections and severity of illness. We chatted about foundational knowledge drawn from studies where people are experimentally exposed to rhinovirus (aka the common cold) before moving to a conversation about health behaviors through the holidays. We hope this episode encourages you to indulge in social support and lean into the joy of this holiday season!

  • Stress Beyond the Individual: The physiological cost of caring with Dr. Tené Lewis
    Dec 10 2024

    Welcome back to the Stress Puzzle! This is the second of two episodes highlighting winners of the Stress Measurement Network's (SMN) Stress Science Paper Award. Today we'll hear from the lead author of the winning paper in the Human Empirical/Clinical category, Dr. Tené Lewis. We discussed the findings of their paper, which highlights the importance of stress experienced by close loved ones (e.g., family, friends) for African-American women's cardiovascular health. We also chatted about the strength of her team's methodology, how they disseminate the research to women who participated in their study, and the importance of these findings for conversations around self-care, care work (whether formal or informal), and the enormous responsibility that falls to women who end up as the social safety net.

    Dr. Tené Lewis is a Professor in the Rollins School of Public Health at Emory University where she studies health psychology and psychosocial epidemiology with an emphasis on cardiovascular health in women. Much of her research investigates the psychological and social factors underlying cardiovascular health disparities for African-American women compared to women of other racial or ethnic groups. Dr. Lewis’ research has been honored by the Health Psychology Division of the American Psychological Association, as well as the recently renamed Society for Biopsychosocial Science and Medicine. Her work has been featured by NPR, Essence Magazine, and the Washington Post.

  • Primate Politics: Intergenerational and experimental evidence with Dr. Jenny Tung
    Nov 26 2024

    Welcome back to the Stress Puzzle! I had the joy of speaking with Dr. Jenny Tung, an evolutionary anthropologist and geneticist who discusses her intergenerational and experimental research showing how the social environment affects health and lifespan in non-human primates. She shared about her creative methods to experiment with social hierarchies and the special experience of collaborating with the other women who have led the Amboseli Baboon Research Project in Kenya. For more on human hierarchies and health, check out our last episode with Dr. Michael Marmot.

    Dr. Jenny Tung is the Director of the Department of Primate Behavior and Evolution at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany and a Professor of Evolutionary Anthropology and Biology at Duke University. She co-directs the Amboseli Baboon Research Project, which started in 1971 and is one of the longest running primate field sites in the world located in Kenya. Dr. Tung investigates the genetic and genomic consequences of social environments in baboons, rhesus macaques, and other social mammals. She has advanced the science on social determinants of health by adding DNA analyses to the decades of behavioral observations in baboons to advance lifespan understanding of social influences on health. She has also combined these lifespan studies with creative experimental methods that provide greater causal evidence for the impact of the social environment and on health. Dr. Tung was named a MacArthur Fellow in 2019 for the depth and translational importance of her research. Learn more about Dr. Tung's research: http://www.tung-lab.org/

    Topics Discussed:

    • Social Hierarchies and Health in Non-Human Primates
    • Lifespan Studies and Social Relationships
    • Plasticity of the Immune System to Changes in Social Environment
    • Methodological Challenges and Future Directions
    • Intergenerational Effects of Social Environment

    Oct 29 2024

    Welcome back to the Stress Puzzle! For this episode, I was joined by Dr. Michael Marmot who is an expert on social status and health. We discussed his seminal work on the Whitehall Studies of British Civil Servants, translating research into policy, and how he remains an "evidence-based optimist" through it all.

    Dr. Michael Marmot is a Professor of Epidemiology at University College London, Director of the UCL Institute of Health Equity, and Past President of the World Medical Association. He has led multiple longitudinal cohort studies that have massively impacted our understanding of how social conditions influence health and aging, including the Whitehall Studies of British Civil Servants and the English Longitudinal Study of Ageing. Professor Marmot has also chaired the Commission on Social Determinants of Health for the World Health Organization and conducted a Strategic Review of Health Inequalities in England to produce evidence-based policy recommendations to support population health. He was recognized as a global health hero at the World Health Assembly in 2019.

    Sep 24 2024
    Welcome back to the Stress Puzzle! For our second episode, I was joined by Dr. George Slavich who is an expert on the conceptualization, assessment, and management of life stress. In this conversation, we talked about the history of how stress has been thought of and measured, the limitations of many of these approaches, and the kind of research we need moving forward to really be able to translate the science to be actionable in people's lives. Dr. George Slavich is a Professor in the Department of Psychiatry and Biobehavioral Sciences at UCLA where he is the Founding Director of the Laboratory for Stress Assessment and Research. He is an expert with enthusiasm for bettering the conceptualization, assessment, and management of life stress and for identifying psychological and biological mechanisms that link stress to mental and physical health.

    For this episode, I was joined by experts in the field of stress, Dr. Elissa Epel and Dr. Wendy Berry Mendes. Dr. Elissa Epel has focused on linking chronic stress to health, and Dr. Wendy Berry Mendes has focused on characterizing acute stress responses. They've been working together for over 10 years and have been co-leading the Stress Measurement Network. In this conversation, we discussed challenges and opportunities in the field of stress science, as well as the goals of this podcast.

    Dr. Elissa Epel is a Professor and Vice Chair in the Department of Psychiatry and Behavioral Sciences at the University of California San Francisco, where she also leads the Aging, Metabolism and Emotion center.
