What can i do to naturally lower my blood pressure?

Exercise, diet, calm: First thorough checkup to make sure BP is not in danger range requiring meds, that exercise is safe and that there is not an easily treatable cause. Then regular cardio workouts 3 times a week, diet to lose excess weight and avoid masses of salt, calming practices such as meditation and yoga may be very helpful as well. If BP well over 140/90, meds are likely to be required even so.
