1.) Meditation –It helps balance your autonomic nervous system, which is responsible for helping your body maintain normal blood pressure. Transcendental meditation, where you repeat a sound or mantra with closed eyes, was shown to be particularly effective.
2.) Acupuncture – blocks the effect of an adrenaline rush. There is an area just above the spinal cord in the brain stem which regulates the release of adrenaline (a chemical that makes hearts pound and blood pressure soar.) Acupuncture can prevent this from occurring by blocking the effect and helping the heart to beat normally and blood pressure remain low.
3.) Isometric hand-grip exercises– In other words, contracting your hand muscles in quick, short bursts, like when you squeeze a stress ball. But it’s not just about reducing stress. Instead, handgrip exercises can directly improve the blood vessels’ ability to relax. Try two minutes of pulse-and-release squeezing, followed by a break of a few minutes, for 12 to 15 minutes, three times a week.
