“It’s impossible for us (humans) to make our thoughts disappear; often, the more we try to suppress them, the louder they become. But practicing meditation can help clear away the mind’s chatter. Studies show that meditating even for as little as 10 minutes increases the brain’s alpha waves (associated with relaxation) and decreases anxiety, depression” fears, concerns and repetitive thoughts.
“Meditation has been shown to increase focus, reduce stress, and promote calmness. It can also help people recognize and accept negative emotions—especially when it is done in combination with mindfulness practices that keep people grounded in experiencing the present. It may be particularly effective when a mediator has social support, such as in a structured group setting or with the help of a friend or family member.”
