(HealthDay News) -- Meditation "may" help lower a person's risk of heart diseaase, the American Heart Association says.
"The key word to remember is may," the association said in a statement released in September.
"The research is suggestive, but not definitive," said Dr. Glenn Levine, who chaired a group of heart disease experts who reviewed 57 recent studies about meditation's effects on heart disease.
Types of meditation evaluated were: Samatha, Vipassana, Mindful, Zen, Raja Yoga, Loving-Kindness, Transcendental and Relaxation Response. Types of meditation that incorporated physical activity -- such as yoga or Tai Chi - were excluded because physical activity itself has been proven to help the heart, the AHA said.
