Researchers have found that meditation lowers levels of stress hormones. In fact, by decreasing the level of one such hormone – epinephrine — meditation has been shown to reduce the amount of cholesterol in the blood and therefore help arteries to remain clear. Reduction of stress hormones also supports the healthy functioning of the immune system.More and more the research is demonstrating that meditation really does us a world of good. So what's stopping you from doing it? :-)
This reduction in stress hormones may be explained by the relaxed state that comes about through meditation. Electroencephalograph (EEG) studies of the brain in those who are meditating show that meditation boosts the intensity of alpha waves – associated with quiet, receptive states — to levels not seen even during sleep. This relaxed state combats anxiety, and this is confirmed by research which has found lowered levels of lactic acid in the blood. (High levels of lactic acid are associated with anxiety.) Another effect of meditation is that breathing slows, so the body uses less oxygen.
Meditation has been found to be particularly helpful for the heart. Meditators have been found to have improved blood circulation, as well as a lowered heart rate, which places less demands on the heart.
