Your blood pressure changes from hour to hour, sometimes even minute to minute.


It jumps around so much that you are more likely to get a good sense of your blood pressure if you check it at home rather than in the doctor's office.

Just a few of the things that can influence your blood pressure:

  • standing up from a chair
  • watching an exciting show on television
  • eating a meal
  • listening to soothing music
  • stress
  • the time of day

The American Heart Association (AHA), American Society of Hypertension, and Preventive Cardiovascular Nurses Association urge people with high blood pressure, or at high risk for developing it through family history, to become blood pressure do-it-yourselfers by measuring your blood pressure at home.
