*Skin irritation – Frequent use can strip away natural oils, causing dryness, redness, or itching.
*Cracked skin & infections – Overuse may damage the skin barrier, making it easier for bacteria and fungi to enter.
*Hormone disruption – Some sanitizers contain triclosan or parabens, which may interfere with hormones if absorbed.
*Weakened immunity – Constantly killing germs may reduce natural exposure, potentially weakening the body’s immune response.
*Alcohol-related issues – High-alcohol sanitizers can cause burns, stinging on cuts, and in rare cases, poisoning if ingested (especially in children).
*Antibiotic resistance – Overusing products with antibacterial chemicals may contribute to resistant “superbugs.”
*Eye & respiratory irritation – Fumes and accidental contact can cause burning sensations in the eyes or throat.
*Environmental harm – Chemicals in sanitizers may pollute water systems and affect aquatic life when washed off.
*False security – Over-reliance on sanitizers may make people neglect handwashing, which is often more effective.
