Health experts debunk common medical claims and internet myths

In an age flooded with online health advice, experts are encouraging people to take a closer look at what’s true, what’s misleading, and what’s potentially harmful when it comes to personal well-being.

Some long-held beliefs don’t hold up under scientific scrutiny. For example, the idea that you must take at least 10,000 steps a day for health benefits has been challenged by research showing that even minimal movement throughout the day makes a difference. A study published in the British Journal of Sports Medicine found that just 2,200 steps daily can reduce the risk of mortality and heart disease.

Other misconceptions can have more serious consequences. It’s often believed that breast cancer only affects women, but men are also at risk and face worse outcomes. Research from Vanderbilt University found that men diagnosed with breast cancer are 19% more likely to die from it than women, in part because they tend to seek medical help later.

Common internet health advice also includes ideas like putting potatoes on your feet to reduce fever or drinking red wine daily for heart health. Scientific evidence does not support either claim. Similarly, wearing sunscreen only when it’s sunny and avoiding vaccines due to autism fears are beliefs that have been repeatedly debunked. Studies from institutions like Johns Hopkins have found no link between vaccines and autism.

Diet and meal timing may also influence health outcomes. A study from Massachusetts General Hospital found that people who restrict their eating to daytime hours and avoid late-night meals may lower their risk of heart disease and blood clots.

While it’s easy to find advice online, experts emphasize that not all claims are backed by data. When in doubt, medical guidance should come from trusted healthcare providers and peer-reviewed research.
