Hypertension as been said is a high bloodpressure which affects your heart and kidneys. You want to have a normal bloodpressure to help yourself staying healthy. The recommended Blood pressure is around 120/80. There are many causes; infections, stress, not relaxed enough, not eating well, to much sodium, too much coffee and sodas, not enough water intake, hormonal imbalance, illnesses….you mention it. When you take your blood pressure;, Sit still, relax for 5 minutes and do not talk. Visualize that your blood pressure is low. Nervousness before your blood pressure is taken will influence your blood pressure which is called white coat syndrome. Yesterday I did a test with a 49 old gentleman, he had an infection in his lip, was stressed out because his wife is very sick, has bills to pay…etc. He had the same question so I took his blood pressure 155/98 too high. I asked him to relax and lay down for 5 minutes and no talk. I repeated the blood pressure again it was 144/89. I did EFT on him, Emotional Freedom Technique. Which takes me a minute? Simple easy acupressure points with affirmations. His blood pressure, still having his infection, came down in 2 ½ minutes to 136/73. He was so relieved and grateful. So funny you ask this question now. See source for more recipes on high blood pressure and enjoy your life, learn EFT, to get a better life.
