Why We Trust Influencers With Our Health: The Power of Social Media Advice

A quick scroll through social media can offer advice and suggestions on everything from nutrition and fitness to mental health and medical care. Health information has never been more accessible, or overwhelming. 

Today, influencers often shape how people think about their health. Many have built large and loyal online audiences by sharing personal stories and seemingly relatable advice. The problem is that while these online personalities may seem trustworthy, most are not healthcare professionals. 

So why do so many people trust influencers for health advice? The answer has less to do with medicine and more to do with human psychology. 

Why Do We Trust Influencers With Our Health? 

Trust doesn’t always come from expertise. It often stems from familiarity. 

Influencers create the illusion of intimacy. They are persuasive because they offer relatable, easily digestible content from a storytelling perspective, something healthcare in a clinical setting can lack. But that relationship is one-sided. 

One of the biggest reasons people lean into influencer advice is because they create what psychologists call a parasocial relationship: a one-sided emotional connection with someone they’ve never actually met. 

“People, at a baseline, are constantly seeking connection and belonging. Having a parasocial relationship allows someone to have that connection without having to invest their own emotional resources,” explains Dr. Jacob Gonzalez, clinical psychologist at Vail Health Behavioral Health. Online parasocial relationships give people the emotional connection they crave without the risk of conflict or rejection. These emotional connections aren’t harmful, but they do make it harder to evaluate fact from fiction objectively.  

Unlike a doctor you might see occasionally, influencers invite followers into their lives daily to witness their struggles, successes and insights into their personal health journeys. Over time, viewers begin to feel a sense of comfort and familiarity.  

Online personas without a medical education aren’t who you should rely on for important health decisions. Instead, there are better ways to find trusted medical information online.  

The Algorithm Knows What You Want 

What shows up in your feed isn’t random; it’s designed as a dopamine factory to keep you engaged. 

That’s because social media platforms are surprisingly good at learning what captures your attention.  

“Social media is engineered in a way that keeps you consuming, with the intention to keep someone engaged with that content for as long as possible,” points out Gonzlalez. 

If you interact with a post about a supplement, sleep or health trend, the algorithm will serve you more content that reinforces that viewpoint. Eventually, repetition can feel like proof. Gonzalez refers to this as repeated exposure theory. 

Additionally, as humans, we tend to seek out information that supports what we already believe. Psychologists call it confirmation bias, and it can be dangerous when you dismiss information that challenges those beliefs. 

One of the simplest ways to counteract this effect is to pause and ask a different question: What’s the evidence against this?  

“It’s important to challenge what we’re hearing in an open-minded way. If something sounds too good to be true, it probably is,” Gonzalez says.  

Seeking out opposing viewpoints and expert opinions from evidence-based sources can help you develop a more balanced perspective. 

Become a Smarter Health Consumer 

The best defense against misinformation is healthy skepticism. The goal isn’t to avoid online health information; it’s to learn how to evaluate it critically. Here’s how to identify credible health information:  

• Check Credentials: Not everyone discussing online health has the training to do so. Trust authors and creators with relevant education, certification and professional experience in the topic they’re discussing. 
• Verify the Claims: Is the creator simply sharing their personal opinions, or does legitimate scientific research back it? A compelling success story may be inspiring, but trust evidence over testimonials. Look beyond the headline or video clip to identify the source of their information. 
• Use Reliable Sources: When researching health information, prioritize organizations and institutions that follow evidence-based practices. Websites ending in .gov, .edu and many .org domains are reliable places to start. 
• Talk to a Healthcare Professional: Social media can be the starting point for curiosity, but it shouldn’t be the final word on your health. When making decisions about treatments, medications, supplements or symptoms, consult a qualified healthcare provider at Vail Health who understands your unique health history. 

Digital Health Literacy 

Influencers excel at building trust through storytelling, relatability and connection. Vail Health providers bring something more important to the table: education, clinical expertise and evidence-based guidance tailored to your symptoms and health history.  

Social media has transformed how we learn about health, but accessibility should never be confused with accuracy. Learning how to find and evaluate trusted medical information online empowers individuals. 

The most informed health decisions happen when curiosity meets critical thinking. By questioning what you see online, checking sources and consulting trusted medical professionals, you can take advantage of the internet’s wealth of information without falling victim to health misinformation on social media.
