Meditating regularly is important, just like sticking to a routine with exercise or a healthy diet. Research — including studies by a doctor at Harvard — shows that the calmness and serenity gained by meditating for about 20 minutes twice a day can really help lower blood pressure for many people. While the necessary amount of time dedicated to meditating each day differs for everyone, practicing for at least 30 minutes every day can make you feel better.
