The body requires an adequate amount of oxygen in the blood. Healthy red blood cells contain between 95 and 100 percent saturation with oxygen, reports Harvard Health Publications. Low blood oxygen, or hypoxemia, may be a symptom of inadequate breathing caused by chronic illness, lack of sufficient oxygen in the environment or bad habits. Blood oxygen levels can be measured by an oximeter, a device clipped onto the finger that shines a light through the finger and registers the saturation of oxygen in the blood. A more accurate test requires a blood sample drawn from the artery in the inner wrist. A value of oxygen less than 90 percent is considered low and may require medical attention.
Step 1
Consult your doctor to determine whether you are experiencing low oxygen levels. Ask for recommendations for lifestyle changes that may improve your lung capacity.
Step 2
Breathe properly. Practice deep breathing by inhaling slowly through your mouth, holding your breath for seven seconds and then exhaling through your mouth. Avoid holding your breath when you are exercising.
Step 3
Practice stress reduction. Stress can raise blood pressure, which alters the flow of oxygen to the body's organs and tissues. Develop a meditation practice or learn yoga or tai chi, and practice daily to improve your oxygen levels.
Step 4
Avoid a high-fat diet. Eat plenty of fruits, vegetables and whole grains, which are all complex carbohydrates that improve oxygen delivery to the cells. If you smoke, stop, and avoid secondhand smoke.
Step 5
Stand up straight. Practice good posture. Consider learning the Alexander technique, a technique that teaches correct posture and movement through proper breathing habits.
Tips and Warnings
- Shortness of breath in the middle of the night may be a symptom of sleep apnea.
- Seek emergency medical treatment if you experience severe shortness of breath.
