The screenshot carries the masthead of BBC News and shows a photo of a man clutching his chest.
Text below the headline reads: “Trial found that people who breathe more than 5 percent above the daily average had a rise in blood pressure and increased risk of myocarditis.”
But did BBC News really publish this article? And does breathing “more than 5 percent above the daily average” really increase the risk of heart attack?
Screenshot fake and claim false
A thorough search of the BBC News website for an article with that headline returned no results. We could find no evidence that the BBC had ever published an article claiming that “breathing too many times a day can cause a heart attack”.
The screenshot is fake.
Mayo Clinic says that some of the symptoms of a heart attack include pressure, tightness or pain in your chest or arms, nausea, shortness of breath and fatigue.
The causes of heart attack listed on the clinic’s website do not include “breathing too many times a day”.
