Indeed, we can't avoid stressful situation, but we can develop mind-body protective ways of responding to them. This is called the "relaxation response” (Dr. Benson, Harvard, 1970’s). It's a state of profound rest that, with regular practice, develops into a sort of personal shield: a source of calmness creating within you that helps you counter the body’s stress response when you need it.
This is a well-studied physiological change that can help reduce your blood pressure and levels of the stress hormone cortisol, slow heart rate, breathing rate, oxygen consumption, and relax muscles.
Research revealed that when blood pressure falls during the relaxation response, inflammation and blood vessel constriction become less active and blood vessels widen.
Back in 2016, the American Heart Association was already studying and promoting the benefits of the TM technique for the cardiovascular system.
According to Dr. Vernon Barnes, in most cases the high blood pressure is reduced after a month or two of practicing TM. By reducing stress, TM profoundly improves cardiovascular health as well as physical and mental health in general. How? Although it is a mental technique, it triggers a unique neurophysiological state, that is shown to lead to lower cholesterol levels and lower blood pressure.
