What lifestyle changes lower blood pressure most effectively?

The five lifestyle interventions with the most consistent evidence for blood pressure reduction, ranked by effect size: (1) weight loss, 5 mmHg systolic reduction per 5 kg lost (largest lifestyle effect); (2) DASH diet, 8–14 mmHg systolic reduction in hypertensive individuals; (3) aerobic exercise, 5–7 mmHg systolic reduction from consistent zone 2 training; (4) sodium restriction below 2,300 mg/day, 2–8 mmHg systolic reduction in sodium-sensitive individuals; (5) alcohol reduction below 2 drinks/day, 3–4 mmHg systolic reduction (Whelton et al., JACC, 2018).

The cumulative effect of all five interventions simultaneously can be 20–30 mmHg systolic, comparable to a first-line antihypertensive medication and sufficient to normalize Stage 1 hypertension without medication in many men. Most men are offered medication before lifestyle optimization is fully pursued. This is not necessarily a clinical error, the urgency depends on the blood pressure level and overall cardiovascular risk, but men with mild to moderate hypertension (130–150 mmHg systolic) who have not yet pursued intensive lifestyle modification have an opportunity to avoid lifelong medication.

Honesty Scale: Solid (1) for all five interventions based on meta-analysis and RCT data.

What to do: Before adding an antihypertensive medication for Stage 1 hypertension (130–139 mmHg systolic), pursue 3 months of intensive lifestyle modification: weight loss, sodium reduction, aerobic exercise, alcohol reduction, and sleep apnea treatment if applicable. Reassess with ABPM after 3 months.
