World Hypertension Day is observed every year to raise awareness about high blood pressure—also called hypertension—and its dangers. This global health campaign highlights the risks of uncontrolled blood pressure, encourages regular check-ups, and promotes healthy living to prevent or manage the condition. Hypertension is a major cause of heart disease, stroke, and kidney failure, but early detection and proper care can help save lives.When is it Observed?World Hypertension Day is marked on May 17 every year. In 2025, it falls on a Saturday—a great opportunity for communities to organize health events, free screenings, and educational drives to spread the message.OriginThe first World Hypertension Day was held in 2005, started by the World Hypertension League (WHL). This global health group launched the day to bring more attention to the rising problem of hypertension. Over the years, more countries and health organizations have joined the movement to inform people about how to prevent, detect, and treat high blood pressure.Significance Hypertension, or high blood pressure, is a condition where the force of blood against the artery walls is consistently too high. According to the World Health Organization (WHO), hypertension is defined as having a systolic blood pressure reading of 140 mmHg or higher, and/or a diastolic reading of 90 mmHg or higher, on repeated measurements.The WHO notes, “An estimated 1.28 billion adults aged 30–79 years worldwide have hypertension, most (two-thirds) living in low- and middle-income countries. Only 1 in 5 people with hypertension have it under control.”High blood pressure is often called the “silent killer” because it usually has no clear symptoms but can cause serious harm to the heart, brain, and kidneys. The World Health Organization (WHO) estimates that about 1.13 billion people around the world suffer from it—many without knowing.
