Understanding Blood Pressure
Blood pressure is a critical indicator of cardiovascular health, signaling how effectively blood is circulating through the arteries. Proper management of blood pressure levels is essential for maintaining heart health and preventing complications.
Definition and Importance
Blood pressure is the force exerted by circulating blood on the walls of blood vessels. It is measured using two numbers: systolic blood pressure—the pressure when the heart beats while pumping blood, and diastolic blood pressure—the pressure when the heart is at rest between beats. Normal blood pressure is vital for ensuring that all body tissues receive adequate supplies of oxygen and nutrients.
High Blood Pressure and Hypertension
High blood pressure, also known as hypertension, occurs when blood moves through arteries at a higher pressure than normal, potentially leading to health issues. Hypertension is diagnosed when blood pressure readings consistently show systolic pressure over 130 mmHg or diastolic pressure over 80 mmHg. It is deemed a 'silent killer' as it may cause damage over time without noticeable symptoms.
Factors Affecting Blood Pressure
Several factors can influence an individual's blood pressure, ranging from lifestyle choices to genetic predisposition. These factors include:
Diet and weight
Physical activity level
Tobacco and alcohol use
Age and gender
Stress level
Underlying medical conditions
Medication
Careful monitoring and management of these factors can help maintain healthy blood pressure levels and reduce the risk of hypertension.
