According to the health body, “to see if caffeine raises your blood pressure, check your pressure within 30 minutes of drinking a caffeinated beverage”.
“If your blood pressure increases by 5 to 10 mm Hg, you may be sensitive to the blood pressure raising effects of caffeine.”
Millimetres of mercury (mmHg) – what does this measurement mean?
Blood pressure is measured in millimetres of mercury (mmHg).
The measurement is used to record two numbers:
- The systolic pressure (higher number) is the force at which your heart pumps blood around your body.
- The diastolic pressure (lower number) is the resistance to the blood flow in the blood vessels.
