Taking some full, steady breaths can be very good at relaxing the body, allowing feelings of panic and worry to be more manageable. It is very good during stressful times but it’s best to make the technique part of your everyday routine so it becomes natural. Find a comfortable position and loosen any tight clothing. If you can, breathe in through the nose slowly and feel the bottom of the lungs gently stretch. You can place a hand on the stomach area to feel the belly rise. Then breathe out through the mouth with pursed lips in a controlled, steady way. Once you know the technique you can try making the out breath longer than the inbreath and use the nose throughout.
