Sodium is known to raise blood pressure (and sometimes greatly), so doctors generally recommend limiting it. Check with your healthcare professional before you up your intake -- if you consume an amount that's not good for you, it can lead to heart failure (especially if you're older).
Even with medication, your blood pressure may still be above normal, and an activity program that is too strenuous could cause your blood pressure to rise to levels that may be unsafe. Generally speaking, your systolic blood pressure (the top number) shouldnât rise too much above 180, and the risk of dangerous events, like heart attack and stroke, rapidly rise as the systolic pressure goes above 200.
