You’ve likely heard the old rule that “normal” blood pressure is 100 plus your age. This idea is outdated and potentially harmful. Relying on it can delay proper care and increase the risk of serious health problems.

Modern medical evidence shows that blood pressure is not meant to rise naturally with age. Higher levels place strain on arteries and vital organs regardless of how old a person is. Even mild, long-term elevation can quietly damage the heart, brain, and kidneys.

Earlier beliefs suggested that readings like 140/90 were acceptable, especially for older adults, or that treatment might be risky. Current guidelines have moved away from that thinking, recognizing that these thresholds are too high for maintaining long-term health.

Today, experts recommend keeping blood pressure below 130/80 for most adults. Research has also shown that treating high blood pressure, even in older individuals, significantly reduces the risk of stroke, heart disease, and premature death.
