Breathing plays a crucial role in maintaining well-being, especially in high-altitude environments where the air is thin. Proper breathing techniques can help alleviate the symptoms of mountain sickness and ensure a more comfortable trekking experience. While many people unknowingly breathe incorrectly, learning to breathe using the diaphragm and practicing full breaths can significantly improve your oxygen intake. In this section, we will discuss the importance of breathing correctly and provide step-by-step instructions for diaphragmatic and full breathing techniques.

Why Proper Breathing Matters

Living at higher altitudes requires our bodies to adapt to reduced oxygen levels. When we breathe incorrectly, we limit the amount of oxygen we take in, making it more difficult for our bodies to function optimally. Chest breathing, which is shallow and limited to the upper part of the lungs, is common among people living in lowland areas. However, this type of breathing is less efficient compared to diaphragmatic breathing, which utilizes the full capacity of the lungs. By learning to breathe using the diaphragm, we can improve our oxygen intake and enhance our overall well-being in high-altitude regions.

Diaphragmatic Breathing Technique

Diaphragmatic breathing, also known as abdominal or belly breathing, involves expanding the stomach while inhaling and contracting it while exhaling. Here’s a step-by-step guide to mastering diaphragmatic breathing:

  • Stand in front of a mirror and place one hand on your stomach and the other on your chest.
  • Take a deep breath. If your chest expands while your stomach remains still or retracts, you are chest breathing.
  • To practice diaphragmatic breathing, engage your abdominal muscles and exhale forcefully, pushing the air out of your lungs.
  • Relax your abdominal muscles and allow your stomach to expand as you inhale deeply.
  • Aim for a longer exhalation than inhalation. This type of breathing promotes relaxation, calms the nervous system, and lowers heart rate.
  • Full Breathing Technique

Once you have mastered diaphragmatic breathing, you can progress to full breaths, which involve coordinating the movement of the chest and diaphragm. Here’s how to perform full breaths:

  • Stand in front of a mirror and place one hand on your stomach and the other on your chest.
  • Exhale by contracting your chest muscles, squeezing your ribs, and engaging your abdominal muscles to push the air out of your diaphragm.
  • Relax your chest and abdominal muscles simultaneously, allowing the breath to naturally enter your lungs.
  • The inhalation should be effortless as your chest expands and your stomach gently rises.
  • Maintain a longer exhalation than inhalation to promote relaxation and efficient oxygen exchange.
  • Understanding Partial Pressure and Its Relation to Mountain Sickness.

To comprehend why breathing becomes challenging at higher altitudes, it’s essential to understand partial pressure. The Earth’s atmosphere consists of various gases, including nitrogen and oxygen. The pressure of each gas contributes to the total atmospheric pressure. Oxygen, which comprises 21% of the air we breathe, has a partial pressure of approximately 160 mm Hg at sea level.

When we inhale, oxygen moves from the atmosphere to our blood due to the difference in partial pressure. As we ascend to higher altitudes, atmospheric pressure decreases, leading to a decrease in oxygen partial pressure. At 5000 meters above sea level, the partial pressure of oxygen is reduced to about 85 mm Hg. However, the partial pressure of oxygen in our blood remains around 40 mm Hg. The disparity in partial pressure hampers the efficient diffusion of oxygen into the blood, resulting in lower oxygen saturation. Simultaneously, carbon dioxide diffusion accelerates, leading to a higher concentration of carbon dioxide in the blood. This imbalance in oxygen and carbon dioxide levels can contribute to the development of mountain sickness.

To put it simply, when we ascend to higher altitudes, the reduced atmospheric pressure makes it harder for our bodies to absorb oxygen. This decreased oxygen availability can lead to symptoms such as dizziness, fatigue, headaches, nausea, and shortness of breath—common signs of mountain sickness.

How Proper Breathing Helps

By mastering diaphragmatic and full breathing techniques, you can optimize your oxygen intake and reduce the risk of experiencing mountain sickness. When you breathe using the diaphragm, you engage the lower part of your lungs, where a greater volume of oxygen exchange occurs. This allows for more efficient oxygen absorption and improved oxygen saturation in the blood.

Furthermore, diaphragmatic breathing activates the parasympathetic nervous system, promoting relaxation and reducing stress levels. It helps regulate heart rate and blood pressure, which are vital for maintaining equilibrium in high-altitude environments.

Steps to Breathe Correctly

Now that you understand the importance of proper breathing and how it relates to mountain sickness, let’s summarize the steps for diaphragmatic and full breathing techniques:

Diaphragmatic Breathing:

  • Stand in front of a mirror and place one hand on your stomach and the other on your chest.
  • Take a deep breath. If your chest expands while your stomach remains still or retracts, you are chest breathing.
  • Engage your abdominal muscles and exhale forcefully, pushing the air out of your lungs.
  • Relax your abdominal muscles, allowing your stomach to expand as you inhale deeply.
    Aim for a longer exhalation than inhalation to promote relaxation and optimize oxygen exchange.

Full Breathing:

  • Stand in front of a mirror and place one hand on your stomach and the other on your chest.
  • Exhale by contracting your chest muscles, squeezing your ribs, and engaging your abdominal muscles to push the air out of your diaphragm.
  • Relax your chest and abdominal muscles simultaneously, allowing the breath to naturally enter your lungs.
  • During inhalation, feel your chest expand and your stomach gently rise.
  • Maintain a longer exhalation than inhalation for optimal relaxation and efficient oxygen exchange.
  • By practicing these breathing techniques regularly, you can train your body to breathe correctly, even at higher altitudes. It’s essential to start incorporating these techniques into your daily life before your trek to ensure familiarity and comfort.

Remember, breathing is a fundamental aspect of our well-being, and mastering the art of proper breathing will not only help prevent mountain sickness but also enhance your overall trekking experience. So, take a deep breath, engage your diaphragm, and embark on your mountain adventure with confidence and vitality.

Happy trekking!
