meditation - how it brings down heart rate and stress

Blood Pressure and Pulse rate of people who meditate significantly dropped in the test subjects. This article also gives us a numeric comparative analysis of the situation. According to the author the reason the subject’s blood pressure drops is because meditation gave the test subjects a sense of tranquility and decreased their autonomous function. Although, the author proved his theory that meditation helped people with hypertension and other problems- he does not provide an analytical solution to the question as to why numbers in question (blood pressure & pulse rate) significantly drop.

The author also gives various insights on other mechanisms such as metabolism, reaction time and total amount of proteins.This article also provides insight on the different kinds of meditation and their usefulness.(eg) Dhammakaya meditation, Samadhi Meditation, Zen Meditation etc.
