Is it possible for two weeks of exercise to lower blood pressure? 49 yo male, six feet tall and 250 pounds. Have led pretty much a couch potatoe lifestyle the last five years (work related, lots of sitting, not much if any exercise). My blood pressure the last two years has been 150 over 100 (average). Can t afford a doc, no insurance. So don t go there. Last two weeks I started playing golf, usually walk 3 hours or 3 miles on the course in hot 90 degree weather. Also started eating oatmeal regularly last two weeks, and a better selection of foods. Also cut out all my caffiene...no coffee. Before, was drinking about 6 cups a day. Yeah, was headed for a heart attack. May still be. Question, with that info, all of a sudden my blood pressure is sitting at an average 120/80 with a pulse of 70....is it possible that in two weeks of no caffiene, lots of exercise and 8 hours sleep instead of 5-6 that my blood pressure would drop this much? Or are these false readings that won t hold up going forward?
