A normal blood pressure reading should be around 120/80 but 135/85 blood pressure reading can be normal depending the person who has that blood pressure.
For some people 135/85 is a high reading and is getting near hypertension and it all depends on the person.
When blood pressure gets to 140 systolic or above then that's when a person should really worry especially if the blood pressure doesn't go down on it's own.
Having too high of blood pressure can damage blood vessels and increases a persons risk for coronary heart disease, stroke, heart attack and death from those health problems.
Try taking a 15 to 20 minute walk when your blood pressure goes up as walking helps to lower blood pressure and is healthy for your body in other ways as well.
You can also lower your blood pressure using Apple Cider Vinegar mixed in with water, lemon juice and organic honey or you can just take a tablespoon of Apple Cider Vinegar once or twice per day to lower your blood pressure.
But if your blood pressure continues to rise or doesn't go down then you might need to see your doctor to get on blood pressure medicine which regulates your blood pressure and keeps the blood pressure at a healthy level.
