How to Improve Blood Oxygen Level Over Time

One of the commonly-overlooked factors for your overall health is your blood oxygen level. Vital to living, adequate oxygen levels in the bloodstream are essential for the proper functioning of our organs and tissues.


Today, we’re discussing what blood oxygen levels are, normal healthy ranges, as well as causes of lowered levels. Continue reading to learn how to improve blood oxygen level metrics over time to live a full, healthy life.

What Is Blood Oxygen Level?


Before we discuss how to improve blood oxygen level readings over time, it’s important to understand what it is. Blood oxygen level, commonly measured as SpO2 (peripheral capillary oxygen saturation), indicates the percentage of oxygen bound to hemoglobin in your bloodstream. Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to tissues throughout the body.


Before 2020, chances are you may not have ever considered your blood oxygen level. The COVID-19 virus highlighted the importance of improving lung function and keeping blood oxygen levels high. It was one of the most measured metrics during the pandemic.


Your blood oxygen level measurement is read as a percentage. Monitoring blood oxygen levels is crucial for assessing respiratory function and overall oxygenation status. Devices like pulse oximeters provide a quick and non-invasive way to measure SpO2, making it a valuable tool in healthcare for conditions such as respiratory disorders and during recovery from certain medical procedures.


Maintaining appropriate levels, and learning how to improve blood oxygen level over time, is vital for overall health and is particularly important for individuals with respiratory or cardiovascular health conditions.

Normal Blood Oxygen Levels


In order to learn how to improve oxygen level in blood over time, you need to know what normal blood oxygen levels are. Be aware that high altitudes and other factors may affect what is considered normal for different people.


Healthy blood oxygen levels typically fall within the range of 95% to 100%. People living with chronic obstructive pulmonary disease (COPD) or other respiratory conditions may have a typical blood oxygen level below this range. A reading below 90% is generally considered low and may indicate hypoxemia, a condition characterized by insufficient oxygen in the blood.


Values outside the normal range can be a cause for concern, potentially leading to oxygen deprivation in tissues and requiring medical attention. Regular monitoring of blood oxygen levels is essential, especially for individuals with respiratory conditions or those recovering from medical procedures.

Causes of Low Blood Oxygen Levels


As mentioned above, low blood oxygen levels, known as hypoxemia, can result from various factors affecting the respiratory and circulatory systems. Understanding the causes of low blood oxygen levels is crucial for accurate diagnosis and appropriate intervention.


Some causes of low blood oxygen levels include:

Respiratory Conditions


Chronic respiratory conditions such as COPD, asthma, and interstitial lung disease can impair the lungs' ability to efficiently exchange oxygen and carbon dioxide. Acute infections like pneumonia may also lead to inflammation and fluid buildup, reducing the surface area available for oxygen exchange.

Cardiovascular Issues


Conditions like heart failure cause a struggle to pump blood effectively, leading to inadequate oxygen delivery to the body's tissues. Severe heart conditions or cardiac events can result in cardiogenic shock, where the heart's pumping ability is severely compromised.

Altitude and Environmental Factors


At higher elevations, the air contains less oxygen which can lead to lower oxygen levels in the blood. This can be a concern for individuals not acclimated to such altitudes but isn’t usually dangerous except at extremely high altitudes. Exposure to pollutants or environmental toxins can also negatively impact lung function and contribute to decreased oxygen levels.

Poor Sleep Quality


Common sleep disorders like sleep apnea are a danger to your overall health. The intermittent pauses in breathing during sleep from sleep apnea can lead to drops in blood oxygen levels, impacting overall oxygenation.

Health Conditions and Injuries


Conditions causing a decrease in the number of red blood cells or a lower concentration of hemoglobin, such as anemia, can result in reduced oxygen-carrying capacity.


Injuries to the chest, such as rib fractures or lung contusions, can compromise the respiratory system, affecting oxygen exchange. Conditions affecting the muscles involved in breathing, like neuromuscular disorders, can lead to respiratory insufficiency and low oxygen levels.


It’s also possible that certain medications may lead to the need for learning how to improve oxygen level in blood. Consult your doctor if you have any concerns or feel off in order to accurately identify the source of the problem and determine a solution. A timely diagnosis and appropriate management are essential to address the underlying condition and optimize oxygenation for overall health and well-being.

How to Improve Blood Oxygen Levels


While short-term strategies for how to improve blood oxygen level readings can provide immediate relief, adopting long-term practices is essential for sustained improvement and holistic health. From targeted exercises to lifestyle adjustments, your approach should encompass a comprehensive approach to respiratory and circulatory health.

Short-Term Blood Oxygen Level Improvement


Short-term methods for how to improve blood oxygen level readings focus on immediate or fast-acting techniques for relief. These may be effective in the moment but need to pair with long-term solutions for better metrics over time.


  • Quick exercise bursts: Short bursts of physical activity, particularly aerobic exercises like running, can quickly enhance lung capacity and oxygen uptake. Exercise stimulates deeper breathing, promoting efficient oxygen exchange in the lungs. Engaging in activities that elevate heart rate also improves blood circulation, aiding oxygen delivery to tissues.
  • Using a zero gravity chair: Reclining in the zero gravity position elevates your legs above the heart level and helps increase blood circulation throughout the body. It reduces excess stress on the heart and could improve lung function. Heated zero gravity chairs may improve your condition even more while relaxing your body and helping with how the body heals itself. These chairs can also double as a long-term method for how to improve blood oxygen level readings when used regularly.
  • Deep breathing exercises: Practicing calming breathing exercises, such as diaphragmatic breathing or pursed-lip breathing, can rapidly increase oxygen intake. These techniques help maximize lung capacity, reduce respiratory rate, and improve the efficiency of oxygen exchange in the lungs.
  • Sitting properly: Similar to using a zero gravity chair for how to improve blood oxygen levels, sitting upright or at a supported angle like the zero gravity position may improve your levels quickly as compared to lying down.

Long-Term Blood Oxygen Level Improvement


Long-term methods for how to improve blood oxygen level readings are vital to your overall health moving forward. Immediate relief from short-term methods should complement these long-term strategies to build a holistic approach to your health.


  • Daily exercise: Incorporating regular aerobic exercise into your routine supports long-term improvements in lung capacity and cardiovascular health. Even low impact exercises like swimming or a brisk walk will make a positive impact. Consistent physical activity strengthens respiratory muscles, enhances oxygen utilization, and contributes to overall respiratory efficiency.
  • Maintain optimal iron levels: Having sufficient iron levels is essential for optimal oxygen-carrying capacity in the blood. Iron is a key component of hemoglobin, the molecule responsible for transporting oxygen. Consuming iron-rich foods or supplements, under the knowledge and recommendation of your doctor, can address deficiencies and contribute to sustained improvements in blood oxygen levels.
  • Healthy lifestyle choices: Adopting a healthy lifestyle, including eating a balanced diet, drinking enough water, and quitting smoking, can positively impact long-term blood oxygen levels.
  • Meditation: Incorporating mindfulness practices like meditation into your daily routine promotes relaxation and reduces stress. Chronic stress can negatively impact respiratory function, so managing stress levels contributes to sustained improvements in blood oxygen levels over time. This is an opportunity to combine short and long-term methods as zero gravity meditation can enhance the benefits of both activities.
