Oxygen Depletion: Subtle Signs Your Body Might Be Lacking This Vital Element

15. Frequent Yawning (Even When Not Tired)

Think yawning is just about boredom or sleepiness? Sometimes, excessive yawning is your body's subconscious attempt to gulp in more oxygen. This reflex temporarily increases lung capacity and boosts blood flow, trying to compensate for lower oxygen levels. If you find yourself yawning frequently throughout the day despite adequate rest, it might be a subtle physiological cue that your brain and body are craving a better oxygen supply.

16. Vision Disturbances

Your eyes are incredibly oxygen-hungry. Even mild shortages can cause symptoms like blurred vision, difficulty focusing, temporary tunnel vision, or seeing spots. The retina and optic nerve are highly sensitive to oxygen fluctuations. Experiencing unexplained changes in your vision, particularly if coupled with other signs on this list, could suggest that compromised oxygen delivery is affecting these delicate structures, signaling a need for investigation.
