Cardiologists warn that small, often unnoticed habits can harm heart health—even when people believe they are taking proper care of themselves.
Sitting too long cancels out exercise benefits
An hour of daily exercise does not counteract the risks of sitting for 10 hours, said Dinesh Kalra, a cardiologist and member of the American College of Cardiology. Extended sitting increases the risk of death from any cause, not just cardiovascular disease. Desk workers can reduce these risks by taking standing or walking breaks, or by holding meetings while standing.
Overlooking high cholesterol
Low-density lipoprotein (LDL), commonly known as “bad” cholesterol, raises the risk of heart attack and stroke when levels exceed 100 mg/dL. Beverly Hills-based cardiologist Pritha Gupta explained that LDL levels typically start low—around 20 to 30—but rise with age and a diet high in processed foods. Statins, supported by decades of research, are a standard treatment. Newer medications are also available for patients who do not respond well to statins.
“If your doctor recommends cholesterol-lowering medication, skipping it puts your health at risk,” Gupta said.

Underestimating family history
Genetics influence heart disease risk even if a relative’s condition stemmed from different factors. Solomon Bienstock, an assistant professor of cardiology at Mount Sinai, stressed that family history should not be dismissed. “When heart disease runs in families, early action is necessary,” he said. “Proactive steps, such as earlier screenings or lifestyle changes, can make a difference.”
The first step is informing a doctor about any family history of cardiovascular issues.
The risks of ultra-processed foods
Kalra offered a simple guideline: if a food would be unrecognizable to earlier generations, it likely harms heart health. Ultra-processed foods, such as deli meats or packaged snacks, are linked to higher risks of heart disease and stroke. “If the ingredient list is longer than your grocery list, reconsider what you’re eating,” he said.
Choosing foods closer to their natural state is a safer option.

Sleep’s role in heart health
Both sleep quality and duration affect cardiovascular health. Gupta cited research showing that people who sleep at least seven hours per night tend to live longer. Sleep apnea, characterized by loud snoring or persistent fatigue, poses additional dangers. Left untreated, it increases the risk of heart failure and other serious conditions.
While traditional advice—such as eating well, staying active, and avoiding smoking—remains important, cardiologists emphasize that these less obvious habits can have an equally strong impact. Small, consistent changes often lead to lasting improvements.
