Oxygen Depletion: Subtle Signs Your Body Might Be Lacking This Vital Element
17. Ringing in the Ears (Tinnitus)

That persistent ringing, buzzing, or hissing sound, known as tinnitus, isn't always just noise. It can sometimes be linked to insufficient oxygen reaching the sensitive hair cells within your inner ear. These cells require a constant, rich supply of oxygen to function correctly. Disruptions in blood flow or overall oxygen levels might trigger or worsen tinnitus, serving as an auditory hint of potential underlying oxygenation issues.
18. Increased Susceptibility to Infections

Your immune system is a complex network that demands significant energy and oxygen to operate effectively. Key immune cells rely on adequate oxygen to patrol your body and neutralize pathogens. If you seem to be catching every bug going around or find infections lingering longer than usual, chronically low oxygen levels might be subtly weakening your defenses, making your body a more inviting target for illness.
