According to the American Heart Association, relaxation that calms tension in the mind and body can be a great way for men and women to combat stress. Deep breathing is one relaxation technique that's simple and effective when done the right way. The AHA recommends that men and women looking to relax through deep breathing should first sit in a comfortable position with their feet on the floor and hands in their lap (lying down is also acceptable). Once they have gotten in position, men and women can close their eyes and picture themselves in a peaceful place, holding the scene in their mind, all the while inhaling and exhaling slowly and deeply. This slow breathing should continue for at least 10 minutes.
