don't be afraid by that.
there are certain factors on why you are having an elevated blood pressure. they are:
1. age - as we get older, BP fluctuates.
4. temperature - the hotter it is, the higher your BP will.
6. diet (lifestyle, vices, etc.)
*the normal BP is...
diastole - 70-90
**but it still depends upon the person...remember that we are "individuals", what is normal with one may not be normal with the other.
***don't take your BP when your exhausted, take a 15-30 minutes break before measuring. and also, dont take your BP if you just ate (you will have an elevated BP if you do so).
