“Many studies have investigated meditation for different conditions, and there’s evidence that it may reduce blood pressure as well as symptoms of irritable bowel syndrome and flare-ups in people who have had ulcerative colitis. It may ease symptoms of anxiety and depression, and may help people with insomnia. Some research suggests that meditation may physically change the brain and body and could potentially help to improve many health problems and promote healthy behaviors. A 2013 review of 3 studies suggests that meditation may slow, stall, or even reverse changes that take place in the brain due to normal aging.”

"We define mindfulness as a moment-to-moment awareness of one's experience without judgment. In this sense, mindfulness is a state and not a trait. While it might be promoted by certain practices or activities, such as meditation, it is not equivalent to or synonymous with them. Several disciplines and practices can cultivate mindfulness, such as yoga, tai chi and qigong, but most of the literature has focused on mindfulness that is developed through mindfulness meditation — those self-regulation practices that focus on training attention and awareness in order to bring mental processes under greater voluntary control and thereby foster general mental well-being and development and/or specific capacities such as calmness, clarity and concentration."

"A number of studies in school settings also show improved attention and behavior. Some research has shown benefits for Attention Deficient Hyper-Activity Disorder (ADHD), anxiety, depression, school performance, sleep, behavior problems, and eating disorders. There are also physical benefits as it calms the nervous system and decreases stress hormones. Studies have shown benefits for gastrointestinal symptoms, obesity, headaches, high blood pressure, pain sensitivity, and immune function." A study in 2013 showed that in boys with ADHD, an eight-week training significantly reduced hyperactive behaviors and improved concentration.
