Meditation for health and well being is being increasingly recognized by modern research.
Research suggests that meditation can be a powerful tool for learning control of attention, regulating emotion, and increasing self-awareness. New scientific data show that during meditation there are a number of measurable biological changes, and the data suggest that meditation has the potential to impact mental and physical health. For example, neuroimaging suggests meditation may have an effect on brain function that persists even when someone is not meditating. Another study showed changes in certain genes related to inflammation and histones.
The scientific evidence to date suggests that mindfulness meditation—a mind-body practice which cultivates abilities to maintain focused and clear attention, and develop increased awareness of the present—may help reduce symptoms of anxiety and depression, as well as menopausal symptoms and the symptoms associated with cancer and treatment side effects.
