Health Reality Check

Social media can connect us, inform us and entertain us. But it can also keep us scrolling, expose us to misinformation and shape how we see ourselves and the world around us. So how do we build a healthier relationship with our digital lives?
In this episode of Health Reality Check, host Dr Margarida Santos speaks with Professor Sander van der Linden, a social psychologist and leading expert on misinformation, about how digital environments influence our behaviour and beliefs. They explore the impact of social media on young people and how platforms could be designed with safety in mind.
They also look at why misinformation is so persuasive, how “prebunking” can help us recognize manipulation before we encounter it, and why curiosity, nuance and an open mind may be some of our best defences online.
The host and external guests participate in Health Reality Check as independent contributors. Their participation does not imply WHO support for all their views, opinions or activities.

Is staying healthy simply a matter of making the right choices? Or are those choices shaped long before we make them? 
In this episode of Health Reality Check, host Dr Margarida Santos sits down with Gundo Weiler, former Director of Prevention and Health Promotion at WHO/Europe, and Allison Ekberg, Technical Officer for Noncommunicable Diseases at WHO/Europe, to unpack what prevention really means. 
From bike lanes and healthier food to taxes, regulation and the information we see online, they explore how the environments around us shape our health, why prevention is often invisible when it works, and what governments, communities and individuals can do to make healthy choices easier.

Millions of people get health information from social media. But how do you tell credible information from viral misinformation? Why do myths spread so quickly online? And what makes people trust one voice over another?
In this episode of Health Reality Check, host Dr Margarida Santos sits down with Dr Mike Varshavski, family physician and one of the world's most-followed health creators, for a conversation about navigating health information in the digital age. Together they explore how to communicate evidence without losing people's attention, the responsibility that comes with influence, and how curiosity can be a powerful antidote to false information.

Many people know WHO from global emergencies like COVID-19. But what does the World Health Organization actually do the rest of the time? How does WHO develop health recommendations ? Does WHO tell countries what to do? And why does trust matter more than ever?
In this special launch episode of Health Reality Check, host Dr Margarida Santos sits down with Dr Hans Kluge, WHO Regional Director for Europe, for a candid conversation about how WHO works behind the scenes, how science becomes public policy, why prevention is often invisible when it succeeds, and the biggest health challenges facing Europe today.
