Belly Button Lint: Why it Forms, How to Prevent It & When to Worry

• Navel lint primarily forms from clothing fibers, especially cotton, due to friction and abdominal hair.
• Sweat, dust, and dead skin cells also accumulate, forming lint, common in hot weather or obese individuals.
• Tight clothing and thick cotton fabrics increase lint formation by enhancing friction.
• Daily cleaning with mild soap, thorough drying, and wearing loose clothes prevent lint accumulation.
• Consult a doctor if lint is accompanied by odor, itching, pain, redness, or discharge, as it may indicate infection.

Why It Matters: Belly button lint is usually harmless, caused by clothing fibers and skin cells; proper hygiene prevents it.
