Normal blood pressure varies from person to person and is influenced by factors such as age, gender, overall health, and lifestyle. Elements like chronic stress, lack of physical activity, excess weight, smoking, and an unhealthy diet can all contribute to changes in blood pressure levels over time. Because blood pressure can rise gradually without noticeable symptoms, it is often referred to as a “silent” health indicator that requires regular monitoring.

The World Health Organization (WHO) emphasizes the importance of maintaining healthy blood pressure throughout life, with particular attention after the age of 45, when the risk of hypertension and cardiovascular disease increases. The WHO’s established blood pressure ranges are widely used as a reference for identifying normal, elevated, and high blood pressure, helping individuals and healthcare providers assess cardiovascular risk and take preventive action when needed.

Blood pressure refers to the force exerted by circulating blood against the walls of the blood vessels. It is measured in millimeters of mercury (mmHg) and is recorded as two numbers. The first number, systolic blood pressure, represents the pressure in the arteries when the heart contracts and pumps blood. The second number, diastolic blood pressure, measures the pressure in the arteries when the heart is at rest between beats.

Both values are important indicators of heart and blood vessel health. Consistently elevated readings can strain the cardiovascular system and increase the risk of heart disease, stroke, and kidney problems. Regular monitoring, combined with healthy lifestyle choices such as balanced nutrition, regular exercise, stress management, and medical guidance when necessary, plays a crucial role in maintaining optimal blood pressure and long-term health.
