Hi Scott,


Your blood pressure on day two is improved, but not within normal yet.


The Joint National Committee defines four blood pressure categories.

Very High Range - Stage 2 Hypertension
Systolic (top) blood pressure 160 mm Hg or high
Diastolic (bottom) blood pressure 100 mm Hg or higher
If in this range you have hypertension (high blood pressure).

High Range - Stage 1 Hypertension
Systolic (top) blood pressure 140 - 159 mm Hg
Diastolic (bottom) blood pressure 90 - 99 mm Hg
If in this range you have hypertension (high blood pressure).

Caution Range - Prehypertension
Systolic (top) blood pressure 120 - 139 mm Hg
Diastolic (bottom) blood pressure 80 - 89 mm Hg
Take action!

Normal Range - Normal
Systolic (top) blood pressure below 120 mm Hg
Diastolic (bottom) blood pressure below 80 mm Hg


Since your diastolic blood pressure (bottom number) is 91, you fall within the "High" range on this day.  Blood pressure is considered to be within normal when it's below 120/80.


All the best,
