Keeping active, slashing salt intake, eating a healthy diet with plenty of fruit and vegetables, cutting down on alcohol and not smoking at all can help reduce the chances of developing the deadly condition.
The World Health Organisation has issued a stark alert, and has demanded "intensified efforts" to prevent and control high BP.
The organisation's director general Dr Margaret Chan told the Daily Express that their aim is to make people aware of the need to know their blood pressure, to take it seriously, and then to take control.
To mark World Health Day on April 7, the WHO wants governments to do more to ensure that people get their blood pressure checked regularly.
Dr Shanthi Mendis, acting director of the Department for Management of Noncommunicable Diseases, said that early detection of the condition is far less expensive for governments than heart surgery, stroke care, dialysis, and other interventions that may be needed if high blood pressure is left uncontrolled.
