We all know that little moment of stress when the blood pressure cuff inflates… But is it really anything to worry about at 135? And is it normal for it to rise a little over the years? Good news: blood pressure changes naturally, and no, it’s not always a problem. Here’s what you need to know to stay calm.
Understanding Blood Pressure
Blood pressure is the pressure of blood against the arteries.
Systolic (the first number): pressure when the heart contracts
Diastolic (the second number): pressure when the heart relaxes
Ideal reference value: 120/80 mmHg… but it varies depending on age, lifestyle, or stress.
Normal blood pressure by age (mmHg)
18–29 years → 115–120 / 75–80
30–39 years → 120–125 / 78–82
40–49 years → 125–130 / 80–85
50–59 years → 130–135 / 80–86
60–69 years → 135–140 / 85–88
70 years and over → 140–145 / 85–90 (tolerated)
These are general values. Guidelines: Only a doctor can make a reliable diagnosis.
