10. Take an Attitude Break

Thirty seconds is enough time to shift your heart's rhythm from stressed to relaxed, Rozman says. The way to do that: Engage your heart and your mind in positive thinking. Start by envisioning anything that triggers a positive feeling -- a vision of your child or spouse, the image of your pet, that great piece of jewelry you're saving up to buy, a memento from a vacation -- whatever it is, conjuring up the thought will help slow breathing, relax tense muscles and put a smile on your face. Rozman says that creating a positive emotional attitude can also calm and steady your heart rhythm, contributing to feelings of relaxation and peace.
