Those that experience anxiety, fear, or panic while driving often report an inability to breathe normally. They may have a feeling of being unable to take a deep breath, as if they’re throat or chest were closing in. They may find themselves gasping and gulping for air or with fears of having a heart attack or lung disorder. Fears of losing control may present themselves stemming from the inability to control one’s own breathing. All of these situations are common with the panic that ensues from a Fear of Driving and cause discomfort and more advanced symptoms, but none are physically dangerous. The goal in learning to breathe properly is not to prevent suffocation or any physical problem, which won’t occur anyway, but to prevent the uncomfortable sensations that result from breathing in this manner. Fortunately, these breathing difficulties can be remedied using simple techniques.
The act of over breathing, or hyperventilating, results in the body taking in far too much carbon dioxide than is needed. Take a look at just some of the symptoms caused by hyperventilation and see if they look at all familiar:
• Racing heart
• Heartburn
• Dizziness
• Vision disturbances
• Numbness or tingling in extremities
• Difficulty in swallowing
• Muscular shaking
• Chest pain
• Sensations of chocking
• Sweating
I’m willing to bet that at least some of the above are sensations of anxiety you experience while driving that you never before attributed to the manner in which you breathe. Learning to breathe in a new way can reduce or eliminate a wide range of complaints associated with the fear of driving. You may likely not even be aware that you’re breathing improperly. You may also not being hyperventilating in the classical sense that you may have seen on television, where the person is gasping for air and they put a paper bag over the mouth (to slow the rate of exhaled carbon dioxide), it’s almost always much more subtle than that. The fearful person is frequently unaware that they are over breathing, but it only take a small change in the mix of oxygen to carbon dioxide to be upset to cause pronounced symptoms and additional anxiety. You may also find yourself holding your breath, which results in the same list of problems.
One of the most widely taught methods of proper breathing is controlled, diaphragmatic breathing. It has been widely known that people with general anxiety, or those subjected to a phobia tend to breathe from their chest (thoracic) and not their stomach (diaphragmatic). It’ easy to tell which you are breathing from whether in everyday situations or while working on your fear of driving.
Place one hand on your navel, and the other on your chest, right over the breastbone. We're going to use your hands will tell you what muscles you are using to breathe. As you breathe, pay attention to which hand is rising and falling. If it is mostly or exclusively the hand on your chest, you aren’t breathing from your diaphragm and need to work on teaching your body to breathe properly. If it is only the hand on your belly moving, then you’re breathing well in this situation but should recheck your breathing when anxious to ensure you maintain your breathing pattern. Sometimes people are reluctant to believe that they’re breathing wrong, but simply look at the way a baby or dog breathes, they breathe in a relaxed manner with their bellies moving up and down, their chest stays still.
If you find yourself needing to correct your breathe, below is a basic exercise that should be done as often as possible to retrain yourself. With enough work you’ll actually move your unconscious breathe from the upper lung to the lower lung and experience greatly reduced anxiety and physical symptoms of tension.
1) Again, place one hand on your navel, and the other on your chest, right over the breastbone.

2) Exhale completely. Drop your shoulders and relax your muscles as you do so, pay particular attention to the muscles of your face and upper body.

3) Pause for three seconds.

4) Inhale SLOWLY through your nose by pushing your stomach out, not your chest. Visualize yourself breathing in and out through your navel. Your chest hand should stay relatively stationary, while your lower hand rises and falls.
There is also a more advanced breathing technique that can help you in the midst of an anxiety or panic attack to actually play a role in eliminating the fearful feelings. The Driving Fear program does an excellent job of teaching the strategy to assist those with more bothersome anxiety, panic, or phobias related to the Fear of Driving or specific driving situations such as highway driving or driving over bridges.
