When was the last time you thought about breathing？ Most people usually do not. When we are healthy， breathing happens naturally and easily. Without much effort on our part， the human respiratory（呼吸的）system works hard. Experts say we take about 20，000 breaths every day.

One such expert James Hoyt with the University of Colorado's Health Pulmonology（肺科）Clinic notes that our respiratory muscles are working every minute of the day. A muscle called the diaphragm （横膈膜）separates the chest and abdominal cavities（腹腔）.As we breathe in， the diaphragm tightens. The chest cavity opens， and the lungs expand. When we breathe out， the diaphragm relaxes and moves upward， pushing air out.

When you breathe deeply， the air coming in through your nose fully fills your lungs， and the lower belly rises. On its website， Harvard Medical School notes that deep breaths may slow the heartbeat， lower blood pressure and reduce stress. Deep breaths help your body fully exchange incoming oxygen with outgoing carbon dioxide.

Several health websites explain an easy deep breathing exercise. Find a place to sit or lie down. Place one hand just below your ribs. Take a slow deep breath—or inhale—through your nose. Feel your hand go up. Your stomach should rise and expand. Now breathe out slowly through your mouth. Make sure to breathe out—or exhale—all the way. Feel your hand and stomach go down.

The American Lung Association website states that if done repeatedly， breathing exercises can help remove stale air from the lungs. This will increase oxygen levels and get the diaphragm to return to its job of helping you breathe. Pulmonologist James Hoyt adds， “Deep breathing is a good way to reduce stress and relax.”
