Loneliness is silently damaging health—here's how to fight back

Loneliness poses serious risks to health, including heart disease, weaker immunity, and cognitive decline. It may even contribute to Alzheimer’s disease. Despite growing digital connections, many people still feel socially isolated. A 2019 study found one in three young people aged 18 to 25 reported feeling socially isolated. The 2026 World Happiness Report also noted that excessive social media use correlates with lower wellbeing. Exposure to exaggerated online content can deepen feelings of loneliness, according to the 2019 Young Australian Loneliness Survey.

Associate Professor Michelle Lim has highlighted that technology connects people but does not guarantee meaningful relationships. She argues that addressing loneliness requires higher-quality, healthier interactions. Experts now advise using social media intentionally to build real-world connections.

In response, Nikol Moses and Isaac Joshi founded Ripple Social to organise in-person events for young people. Their activities have helped attendees form lasting friend groups. More than half of young people surveyed by Headspace in 2023 expressed a desire to step back from social media. The link between loneliness and poor health is well documented. Initiatives like Ripple Social aim to foster genuine connections. Experts continue to stress the importance of face-to-face interaction for long-term wellbeing.
