"How you breathe can make a difference in how you feel. When you are stressed, nervous, frightened, worried or angry, you may notice that your breathing gets low and fast. Your breath will come from higher up in your chest when you are upset. In calmer times, your breathing will be slower and deeper. Your breath will come more from your stomach and underneath your ribs.
You can learn to slow down your breathing, making each breath longer and deeper. This will calm the rest of your body and your mind. If you practice doing this you can become good at staying calm or return to feeling calm quickly in very stressful situations.
Breathing well is good for our bodies and can help us change negative things happening in our minds to more positive. In other words, we can learn ways to use our bodies to help us feel better in our minds."
