The calm.com website is your one-stop for relaxation. You can pick a scenery -- from a soothing stream running through a field to a sun setting over the horizon as the waves crash on the shore -- for a set of time you pick, either a quick 2 minutes or the whole tour for 10. For added relaxation, you can even select a guiding voice that will take you to your inner self and, once the two have met, back out again.
