Marvin OnumonuAviva’s Story of Health research found 25 to 34-year-olds reported higher wellbeing at work than other age groups.
Three quarters rated their mental health as good or excellent, compared with a 62% average across all ages.
Happiness was also higher, with 73% saying they felt happy, compared to 59% for all groups.
Social connection was important, with over a quarter (28%) of 25 to 34s saying they regularly joined community groups or clubs, almost double the 15% average for all ages.
Around 73% volunteered, with 20% doing so through their employer.
This compares to 43% volunteering across all age groups.
About 68% felt a sense of belonging to their local community, higher than any other age group.
Three quarters (73%) intentionally spent time in nature to support wellbeing, compared to 65% for all ages.
Two thirds (66%) of all respondents with good mental health said they felt a sense of belonging in their community, while only one in five (20%) with poor mental health felt the same.
The research found more people turning to social prescribing, such as nature walks, gardening or volunteering, as an alternative to medication.
Over two thirds (68%) of 25 to 34s said they would consider this, compared to 58% for all ages.
Dr Subashini M, medical and sustainability director at Aviva Health UK, said: “Wellbeing isn’t just about individual habits.
“It’s about feeling connected, supported and part of something bigger.
“Social connection is one of the most powerful drivers of health and wellbeing.”
Dr Subashini added: “Whether it’s a chat with a colleague, support from family, or simply feeling part of a community, these moments of connection can help lift mood, reduce stress, and build resilience.
“Employers have a vital role to play in fostering these connections.
“The workplace should be a space of psychological safety, where people feel seen, heard, and valued.
“Wellbeing isn’t just about individual habits—it’s about the people around us, and the strength we draw from them.”
