Systolic pressure is when the heart pumps; diastolic is when it rests. Both matter — a healthy adult typically sits around 120/80.
Every time your heart beats, it pushes blood into the arteries. That push creates two numbers: systolic (top) is the peak pressure during a beat, diastolic (bottom) is the resting pressure between beats.
A healthy adult range is commonly 120/80 mmHg. Consistently over 140/90 is generally considered high, and often improves with lifestyle changes: less salt (India runs high — try to cut pickles, papad, and packaged snacks), more potassium (banana, coconut water, tomato), regular walking, better sleep, and stress management.
Low readings (below 90/60) with dizziness or fainting should be checked by a clinician.
