This technique is called the deep breathing exercise. Smokers who successfully quit report that this is one of the most effective things they used while they were giving up cigarettes.
You can use this deep breathing exercise almost anywhere -- at home, at work, when you are alone or with other people. It is very simple but really helpful. When you get an urge to smoke or start feeling angry, stressed, sad or anxious, just follow these steps until the feelings pass:
Sit in a quiet place with no interruptions. Drop your shoulders...
Place your left hand on your abdomen and right hand on your chest.
Inhale slowly through your nose and exhale slowly through your mouth.
Breathe slowly and deeply, fully expanding your belly as you breathe in, deflating it as you let the air back out.
Practice breathing so your left hand moves out when you inhale, while your right hand moves only slightly.
As you exhale, your right hand remains still while your left hand goes back down.
Each time you exhale, think of the tension, craving or bad feeling leaving your body.
Repeat this pattern until the stress or craving to smoke subsides.
