Pufnstuf Asked: How can I naturally lower my blood pressure?

I am 24 yr old female and am healthy although I do have some anxiety problems. Today I checked my blood pressure and it was like 145 over 80. I checked i several times and it was still in that range. I am about 10 lbs over weight but I want my bp to be lower. What do I need to do to accomplish this and what could be causing it to be this high.
