Our study on daily stress and heart rate variability was featured in the Washington Post (5 March 2018).
Dr. Sin gave a talk on “Small Actions to Promote Happiness and Healthy Aging” as part of the Aging Consciously lecture series at South Arm Community Centre in Richmond (17 Jan 2018). A big thanks to everyone who attended!
The latest newsletter for the Midlife in the United States Study describes findings from Dr. Sin’s studies on daily stress, positive events, and inflammation. Read the newsletter here to learn more about how inflammation interacts with psychosocial and behavioural factors to influence health.

Our research is focused on understanding psychosocial well-being and biobehavioural mechanisms underlying healthy aging.
In a Q&A, Dr. Nancy Sin shares her research and what sparked her interest in studying psychosocial well-being, aging, and health.
First of all, can you tell us a little about yourself?
I am a health psychologist focused on understanding psychosocial well-being and biobehavioural mechanisms underlying healthy aging. I received my PhD in Social/Personality Psychology with an emphasis on Health Psychology from the University of California, Riverside. I subsequently completed postdoctoral research fellowships in the Division of Geriatrics at the University of California, San Francisco and in the Center for Healthy Aging at The Pennsylvania State University. I was born and raised on the west coast (northern California), so Vancouver—the vibrant city, cultural diversity, outdoorsy lifestyle, and beautiful landscapes—already feels like home.
What kinds of questions do you try to answer through your research?
My primary research question is, “How do the ups and downs of day-to-day life influence long-term health and aging?” To answer this question, I examine physiological and behavioural pathways (such as inflammation, sleep, and physical activity) that may link daily experiences to chronic diseases and mortality. I am particularly interested in studying positive events in everyday life and whether they might buffer against the effects of stress.
Can you give us an example of this in our daily lives?
Minor stressors and positive events are common occurrences in daily life, especially in midlife when adults are juggling the demands of family and work responsibilities. In my research, participants have reported positive events such as spending time in nature, having a good conversation, receiving a compliment, and accomplishing a task at work or at home. Examples of stressful events in daily life are work deadlines, being stuck in traffic, having a disagreement or interpersonal tension, and experiencing discrimination or unfair treatment. I (and others) have found that positive events occur far more frequently than stressors among community-based, non-clinical samples of midlife and older adults.
How did you become interested in this line of research?
As one of my work-study jobs when I was an undergraduate at UCLA, I transcribed recordings of marriage therapy sessions. These couples had deeply entrenched problems in their relationships, yet I was most struck by the seeming lack of positive experiences. That job, along with my coursework and other research activities, sparked my interest in whether positive experiences could help alleviate depressive symptoms and counteract stress. I pursued this line of work in graduate school at UC Riverside, where the health psychology graduate courses opened up a whole new world for me that further developed my interests in psychosocial well-being, aging, and health.
Can you tell us about any new research that you are particularly excited about?
I am excited about tracking intraindividual fluctuations in functional and subjective health. In other words, why do we feel healthier and are better able to carry out daily activities on some days than on others? I am also excited about characterizing the processes surrounding daily positive events—that is, individual differences and contextual factors that predict exposure to positive events, as well as appraisals, physiological and emotional responses, and the lingering effects of positive events. My overarching goal is to identify aspects of day-to-day life that can be modified to promote health and well-being.
Do you have a motto?
I do not have a motto, but I believe that every endeavour worth pursuing requires a great deal of practice, persistence, and risk-taking. And, defeat and setbacks should not be interpreted as failure; rather, they are signs of progress towards success.
What do you like to do in your free time?
I love spending time with friends, family, and my two dogs, Muffet and Luke. Because research projects can take years, I like to balance them out by doing creative activities in which I can produce something tangible right before my eyes, including knitting, crocheting, drawing, and cooking.
This Q&A was originally featured on the Department of Psychology’s website.
Our work demonstrates that daily positive experiences are associated with lower inflammation, adaptive cortisol profiles, and better health behaviours.
We have found that maintaining positive emotions in the face of stress is important for health.
