Meditation is a practice where an individual uses a technique to achieve a mentally clear and emotionally calm state of mind. This practice can include mindfulness, focusing your mind on a particular object, activity or thought, breath awareness, etc.
Meditation is a simple, quick way to reduce stress and anxiety. It can also decrease physical pain, increase positive emotion, decrease depression, and increase immune function. A UCLA study found that long-term meditators had better preserved brains than non-meditators as they aged.
