Oxygen is essential for survival. When you breathe, your lungs absorb this vital element and send it, via red blood cells, to all the organs and tissues of the body. However, low blood oxygen levels can have serious consequences, damaging essential organs such as the heart, liver, and brain. What are the causes? What are the warning signs? This article details everything you need to know and offers simple solutions to improve your health .
Causes of a drop in blood oxygen
Several factors can cause a decrease in blood oxygen levels:
Chronic lung diseases : Asthma, bronchitis, emphysema, COPD or pneumonia can limit the lungs’ ability to take in oxygen.
Smoking : Cigarette smoke reduces the effectiveness of hemoglobin, the protein in red blood cells responsible for transporting oxygen.
Stress and anxiety: High levels of cortisol, the stress hormone, can cause hyperventilation and disrupt the balance between oxygen and carbon dioxide in the blood.
Sleep apnea : Snoring or apnea limits oxygen supply during the night, causing episodes of decreased oxygenation.
Excess sugar : A diet rich in refined carbohydrates acidifies the blood, which impairs the proper diffusion of oxygen.
Vitamin and mineral deficiencies : A lack of vitamin E, B1, B12, D, C, iron or zinc can lead to anemia and reduce the blood’s ability to transport oxygen efficiently.
8 warning signs of low oxygen levels
1. Sensation of shortness of breath (Dyspnea)
Low oxygen levels can cause shortness of breath or an increased need to breathe deeply. This symptom is often accompanied by chest tightness and frequent sighing, signs that the blood is becoming too acidic to carry oxygen properly.Chemistry
2. Dizziness and weakness
