How effective is social media for spreading public health advice compared to traditional media?
I'd argue it's far more immediate and engaging than things like billboards or television adverts, especially for younger demographics. Because content is interactive, users can share posts and discuss advice within their own social circles, which builds trust. For example, short video tutorials on basic nutrition often go viral quite quickly. However, the downside is that important messages can easily get buried beneath entertainment content unless they are exceptionally well produced.

Why do some online health campaigns fail to persuade people to change their habits?
I suppose the main issue is that modern audiences suffer from information overload. People are constantly bombarded with conflicting lifestyle advice, so they tend to become cynical or simply tune it out. A fitness campaign might look appealing, but if it demands drastic, unrealistic lifestyle changes, most viewers will just ignore it after a few days. So, unless the advice is genuinely manageable, people won't alter ingrained habits.

Do governments have a duty to regulate health claims made by influencers online?
Yes, I definitely believe public authorities should step in when medical misinformation is being promoted for profit. Many online figures endorse unverified supplements or extreme diets purely for commercial gain, which can cause genuine physical harm to vulnerable followers. For instance, detox teas have occasionally caused serious digestive issues. That said, enforcing these rules across global platforms is obviously quite tricky in practice.

How might digital health communication change over the next decade?
In the coming years, I suspect health guidance will become far more tailored to the individual rather than being broadcast as general advice. Wearable devices already track our daily steps and heart rate, so public health organisations might use that data to send personalised wellbeing prompts directly to our devices. Having said that, that level of tracking could raise serious privacy concerns among the general public.

What are the drawbacks of relying on internet platforms for medical information?
The greatest hazard is undoubtedly the lack of quality control and the risk of self-diagnosis. When people search their symptoms online, algorithms often highlight the most alarming conditions, creating unnecessary anxiety, which is often termed 'cyberchondria'. Moreover, laypersons usually lack the clinical expertise to distinguish between evidence-based advice and pseudoscientific nonsense, potentially delaying proper medical treatment.
