Factors Affecting "Normal" Blood Pressure
Blood pressure changes frequently throughout the day. Things that can make it change within a few minutes include:
- Posture
- Amount of tension
- Level of exercise
- Nicotine use.
It's easy to see why even normal blood pressure can fluctuate within a certain range every day. Given these expected fluctuations, it's best to use more than one
blood pressure reading to figure out your normal blood pressure.
Blood pressure can also run high or low in families. Therefore, it's important to look at your overall health, lifestyle, diet, and family history when comparing your blood pressure to what's considered "normal blood pressure." These factors may cause you to have a higher or lower reading than what's considered normal.
