You’ve likely heard the old rule: “Normal blood pressure is 100 plus your age” (e.g., 140/90 for a 40-year-old). This is dangerously outdated advice—and following it could put your health at serious risk.

Let’s clarify with current medical evidence: Major health organizations no longer define “normal” blood pressure by age. Elevated blood pressure harms arteries and organs at any age—and treating it saves lives, even in older adults.

 The Critical Update: Age-Based Targets Were Abandoned for a Reason

Old Belief (Pre-2017)	Current Medical Consensus
“Higher BP is ‘normal’ as you age”	False—arteries don’t “need” higher pressure with age. Elevated BP damages organs regardless of age
“140/90 is acceptable for seniors”	Outdated—2017 ACC/AHA guidelines lowered threshold to 130/80 for all adults
“Don’t treat BP in elderly—it’s risky”	Debunked—landmark SPRINT trial showed treating to <120/80 reduced death/stroke by 27% in adults 75+
