Blood pressure measures the force of blood pushing against the walls of your arteries. It’s expressed as two numbers:
-
Systolic pressure (top number): Pressure when the heart beats
-
Diastolic pressure (bottom number): Pressure when the heart rests between beats
💡 Example: 120/80 mmHg is considered normal for many adults. Both numbers are important — high or low readings can impact your health.
