Interestingly, the American Heart Association has no definition. It says: “Within certain limits, the lower your blood pressure reading is, the better. There is also no specific number at which day-to-day blood pressure is considered too low, as long as none of the symptoms of trouble are present.” I am not advocating for medicines to push BPs down to ultra-low levels, but many of us can push a few lifestyle parameters to improve. The approach dropped my systolic BP down over ten points in a year. I know some have the genetics or other issues that make them candidates for anti-hypertensive meds (and for them, such medicines can provide tremendous benefits). Thank you for reading the piece and for your Q. Apologies for not making “shallow” (I don’t like that word; not sure why I used it) clear. Hoping you have a fabulous day.

So shallow = low, but AHA has not clear definition of low. I think symptomatic counts.

Warm regards,
