Blood Pressure: The Two Numbers Every Adult Should Know

Targets to anchor on

Optimal: under 120/80 mmHg. Elevated: 120–129 systolic / under 80 diastolic. Stage 1 hypertension: 130–139 / 80–89. Stage 2: 140+/90+. Half the adults with hypertension don't know they have it because there are no obvious symptoms until late.

How to measure honestly

Sitting, feet flat on the floor, back supported, cuff at heart height, after 5 minutes of quiet. Two readings, one minute apart. Take 3 days of morning + evening readings and average — single clinic readings are notoriously inflated ("white-coat hypertension").

The biggest non-medication levers

Walking 30 minutes most days drops systolic by ~5 mmHg. Reducing sodium toward 2 g/day adds another 5. Losing 5–10% of body weight (if overweight) adds another. Limiting alcohol to <1 drink/day for women, <2 for men adds another. Stacking 3 of these often beats a starting dose of medication.
