Ideally, we should all have a normal blood pressure at or below 120 over 80 (120/80). This is the ideal blood pressure for people wishing to have good health. At this level, we have a much lower risk of heart disease or stroke.
Normal blood pressure is having a blood pressure reading that is above 120 over 80(120/80), but below 140 over 90 (140/90). If your blood pressure is within this range, you should be taking steps to bring it down, or to stop it rising any further.
The reason why people with normal blood pressure readings should lower it is that the higher your blood pressure, the higher your risk of health problems. For example, a blood pressure level of 135 over 85 (135/85) may be “normal” but someone with this reading is twice as likely to have a heart attack or stroke as someone with a reading of 115 over 75 (115/75).
