It's common knowledge and well-supported by research:

Meditation has innumerable benefits for our mental & physical wellbeing.

The app I recommend most to my clients is the Calm app. Kaiser members can enjoy a nice benefit: a free year of Calm Premium. 

To access this benefit, simply visit this link, click "Try Calm", sign in to your Kaiser account when prompted, and you're in!
