Hypertension is another name for high blood pressure. High blood pressure forces your heart to work harder to pump blood. This can cause problems over time.

There are two numbers in a blood pressure reading. There is a top number (systolic) over a bottom number (diastolic). It is best to have a blood pressure that is below 120/80.

• If you drink alcohol:
  • Limit how much you have to:
    • 0–1 drink a day for women.
    • 0–2 drinks a day for men.
