Many Americans Unaware That High Blood Pressure Often Has No Noticeable Symptoms

High blood pressure, also known as hypertension, is a widespread chronic condition that can significantly increase the risk of serious health issues such as heart attack and stroke—the leading causes of death in the United States. According to recent data from the Annenberg Public Policy Center’s health survey conducted in April 2025, nearly half of American adults have been diagnosed with high blood pressure, with 35% reporting a prior diagnosis. Despite its prevalence, many Americans remain unaware of what constitutes a high blood pressure reading; only about 13% correctly identify the threshold of 130/80 mm Hg or above.

The survey highlights a common misconception: over a third of respondents believe that high blood pressure always presents noticeable symptoms like dizziness or shortness of breath. In reality, high blood pressure is often symptomless, which is why it is often called the 'silent killer.' Similarly, a significant portion of people mistakenly think that feeling calm or relaxed indicates normal blood pressure, which is false.

Knowledge about the risk factors and management of hypertension is generally good. Most Americans are aware of effective measures to lower blood pressure, such as maintaining a healthy weight, exercising regularly, and reducing salt intake. Furthermore, many express willingness to follow medical advice, including taking medications and monitoring blood pressure at home.

However, despite awareness about preventive behaviors, actual engagement in healthy habits like consistent exercise and salt reduction varies. For example, only about 57% of people report engaging in healthy behaviors more than once a week, indicating a gap between knowledge and practice.

Healthcare professionals emphasize the importance of correcting misconceptions: since controlling blood pressure can drastically reduce the risk of heart attack and stroke, public health initiatives should focus on increasing awareness of what constitutes high blood pressure and its asymptomatic nature.
