Breathing is the process our bodies use to take in air and release carbon dioxide. When we inhale, our lungs fill with oxygen, which is essential for our cells to produce energy. This oxygen travels through our bloodstream to every part of our body, helping us stay alive and active. When we exhale, we push out carbon dioxide, a waste product created by our cells. This cycle of inhaling and exhaling is vital for our health. Activities like yoga and meditation often focus on breathing techniques to promote relaxation and mindfulness, showing how important breathing is beyond just survival.
