The University of Johannesburg (UJ) recently hosted a public lecture on health, wellbeing and behavioural change, featuring visiting scholar Professor Koustuv Dalal from Mid Sweden University. The lecture, hosted by Professor Corne Davis-Buitendag, explored how everyday lifestyle choices and social behaviours shape long-term wellbeing.
Professor Dalal, a research professor in Public Health Economics, is internationally recognised for his work in public health science and behavioural practices. Addressing students and staff, he emphasised that health should not be viewed solely as an individual responsibility, but as a broader societal concern requiring collective awareness and action.
Drawing on research and practical examples, Professor Dalal highlighted how small daily habits related to food, safety, movement and social interaction can contribute positively or negatively to overall wellbeing over time. He encouraged the audience to reflect critically on modern lifestyles and the growing impact of technology and social isolation on mental and emotional health.
“As human beings, we are at the centre with our ego. But we should be part of nature. Because from the ego, if you cannot delete the ‘E’, you cannot go,” said Professor Dalal.
The interactive session included discussions and practical demonstrations focused on manageable lifestyle interventions, including workplace stretches, healthy exercise habits and the importance of social connection in maintaining wellness. The lecture also explored the relationship between social environments, emotional wellbeing and community health.
Professor Pragna Rugunanan, Vice-Dean of Research in the Faculty of Humanities, reflected on the broader societal implications raised during the lecture.
“You also mentioned that health is not purely a personal matter; it is a societal responsibility. As we become increasingly engrossed in technology, we are losing social connection and communication. The connections we make between our daily behaviours and their broader consequences offer us all much to reflect on — and ultimately to act on,” she said.
Students who attended the lecture described it as insightful and thought-provoking. Ramolokwane Malebo Ledwaba said the discussion encouraged deeper reflection on the ways people approach health in the digital age.
“While society places significant emphasis on physical health and appearance, we often neglect equally important aspects of wellbeing such as social health and meaningful human connection,” said Ledwaba.
The lecture formed part of UJ’s ongoing commitment to creating spaces for critical engagement on issues affecting society, health and human development.
