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.
