Understanding the Effects of Hyperventilation

Why does hyperventilation make you feel like you need to breathe more?

Hyperventilation is a condition where a person breathes rapidly and deeply, often faster and deeper than the body requires. This may cause a feeling of needing to breathe more, but it is actually due to changes in the levels of certain gases in the bloodstream.

When we breathe, we take in oxygen and release carbon dioxide. Normally, the rate of breathing is regulated by the levels of carbon dioxide in the blood. Carbon dioxide acts as a chemical signal for our body to breathe.

During hyperventilation, however, we are exhaling more carbon dioxide than our body’s production rate. This leads to a decrease in the carbon dioxide levels in the bloodstream, a condition called hypocapnia. The decrease in carbon dioxide can trigger various physiological responses in our body, including an increase in the pH of the blood (respiratory alkalosis).

An increase in blood pH can cause several symptoms, such as lightheadedness, dizziness, tingling sensations, and a feeling of shortness of breath. These symptoms are the body’s way of trying to restore balance.

However, it is important to note that the feeling of needing to breathe more during hyperventilation is not due to a lack of oxygen. In fact, hyperventilation leads to an increase in the amount of oxygen in the blood because we are breathing in more than we actually need.

To alleviate the symptoms of hyperventilation, it is recommended to slow down breathing, breathe into a paper bag, or practice relaxation techniques to restore the balance of carbon dioxide in the bloodstream and normalize breathing.
