Anti-stress kit

Is there a way to get rid of stress in a shorter time? There is, it's by inhaling and expanding your stomach, while exhaling out with your mouth sucking in your stomach. The longest one is resting by looking out of your window or listening to peaceful music or taking a walk in a breezy park. The one which require items is squeezing a ball or a soft toy or getting a massage. Hope you get stress-free!!!
