An optimal and healthy blood pressure is 120/80 and anything above 120/80 is high.
140/90 or higher is getting into the dangerous range and really should be checked out.
If it gets to 150 or above then you really need to call an ambulance especially if it doesn't go down soon.
Having high blood pressure is serious and could lead to stroke,heart disease and even a heart attack.
Taking Apple Cider Vinegar can help to lower your blood pressure as well as walking 15 to 20 minutes per day everyday and it can also keep your blood pressure at normal levels and prevent it from getting high again.
