To do Heart-Focused Breathing:

Breathe deeply but normally and imagine your breath coming in and going out through your heart area. Continue breathing with ease until you find a natural inner rhythm that feels comfortable.

Focus your attention on the area around your heart, the area in the center of your chest, placing your hand there if you like.

As you continue your heart breathing and heart focus, activate a positive feeling such as appreciation, love or care. An easy way to do this is to remember a special place you’ve been to or the love you feel for a close friend, family member or treasured pet.

Practice Heart-Focused Breathing a few minutes at a time, two or three times a day.
