Labor Day is often considered the unofficial start of fall even though the Autumnal Equinox does not occur until September 22. In many parts of the country, the school year begins right after Labor Day as well. For those of us with children (or those of us in school ourselves), this comes as a huge change to the daily routine we may have developed during the summer. While change can be beneficial, it can also be stressful and nervewracking. Your breath literally can either contribute to anxiety or help manage it. When you "overbreathe" or hyperventilate, the heart rate elevates and the muscles tense. You may even experience dizziness or feel lightheaded. On the other hand, long exhalations or slow breathing can shift the nervous system towards a more restful state, resulting in positive changes like a lower heart rate and lower blood pressure.
Every system in the body relies on oxygen. From cognition to digestion, effective breathing can not only provide you with a greater sense of mental clarity, it can also help you sleep better, digest food more efficiently, improve your body’s immune response, and reduce stress levels. When you inhale, the muscle on the bottom of your ribcage, called your diaphragm, contracts and moves downward. This allows the lungs to have ample room to expand. The muscles between your ribs, called the intercostal muscles, contract to pull your ribcage upward and outward. As your lungs expand, air is sucked in through your nose and mouth and travels down your trachea to your lungs. After passing through your bronchial tubes, the air finally reaches the air sacs where oxygen is passed into the blood stream. At the same time, carbon dioxide travels into the air sacs from the blood stream and is expelled from the body as you exhale. On average, this process is repeated between 17,000-30,000 a day, every day, as long as a person is alive.
Breathing not only fuels the body with oxygen, it can also clear a foggy mind and help strengthen the muscles. Yet few people learn how to breathe in a way that allows the body to function the way it should. Posture has an important impact on our breath. Sitting up straight allows the lungs to expand quickly and efficiently with every breath. Proper posture also helps air to travel into the lungs and carbon dioxide to travel out of the lungs unimpeded. If you are sitting at your desk and feel foggy or otherwise uninspired, take a moment to reposition your body with a straight back to notice an immediate improvement at how well oxygen is reaching your bloodstream and thereby your brain.
While many people focus on completely inhaling in order to improve their breathing, most people only exhale 70% of the carbon dioxide in their lungs. Think about pushing all of the air out of your lungs as though you are blowing bubbles. Not only will your body reward you with instant energy, you will notice how much more efficient you are in filling your lungs.
In order to train yourself to breath properly, like with any skill we aspire to learn, practice makes perfect. Close the mouth and take a slow breath in through the nose, while feeling the abdomen rise and inflate like a balloon. Breathe out slowly through pursed lips, as if blowing bubbles, with each expiratory breath taking about two to three times as long as each inhalation. Repeat these steps for 5–10 minutes.
