Shared Joy, Lower Stress: Study Highlights the Health Benefits of Connectionโ in Aging
A new US study โฃreveals a strong link between experiencingโ positive emotions together and โlower levels of the stress hormone cortisol in older adults. Researchers at the University of California, led by Tomiko Yoneda, are investigating how to promote healthy aging and the role positive feelings play in that process.
The research, a meta-analysis of data โฃfrom over 642 individuals (including 312 couples) โคaged 56-89 from Canadaโข and Germany, demonstrates the powerful impact ofโ sharedโฃ experiences. Participants โขtracked their moods and provided saliva samples to measure cortisol levels over a week.
Cortisol, naturally highest in the morning, spikes briefly duringโ exciting or joyful moments โbefore returning to baseline. However, chronic โคstressโข and aging often lead to consistently elevated cortisol levels, negatively impacting healthโฃ – leading to sleep disturbances, weakened immunity,โฃ and increased risk of cardiovascular disease.
The key finding? Couples who shared positive emotions experienced lower cortisol levels,โ with benefits extending into the following day. Individual happiness or โoverall relationship satisfaction weren’t the deciding factors.”it’s not about how happy you are, but that you’re happy together – sharing joy, relaxation, โor โeven simple โinterest in the same moment,” explains Yoneda.
This research supports the principles of โฃpositive psychology, which suggests that focusing on positive emotions can broaden perspectives, โfoster resilience, and improve overall well-being. Theโข “Broaden-and-Build Theory” โคposits that positive emotions lead โฃto new ideas and stronger relationships.
Yoneda believes these findings have implications for healthcare, suggesting thatโ interventions focused on cultivating shared positive experiences couldโ be a valuable tool for health prevention. She is now exploring whether these benefits extend beyond romantic โrelationships to other connections, like those within families and friendships, โpotentially opening new avenues for improving the health of all โ older adults, including those who are single.
