Normal blood pressure is anything below 140/90 mmHg
For a long time the medical standard for high blood pressure was considered 140/90 and this was further moderated by age. But suddenly the standard was changed. Now some doctors call even 130/80 "high blood pressure" and many others consider it "pre-hypertension". New medications to treat "pre-hypertension" are even underway! The fact is that blood pressure varies widely among healthy people and usually increases with age. Many things can increase blood pressure including over-the-counter and prescription medications, stress and over-indulgence in alcohol. Add to this the fact that blood pressure varies, sometimes significantly, at different times of the day. Sometimes stress of a doctor's visit shows up as high blood pressure while readings taken relaxing at home can be "normal".
