In Short

Because dry friction is unsuited to cleaning up a moist bodily process. It’s a stopgap that became the norm.

What We Were Sold as Normal

Toilet paper counts as the hygienic standard. It’s available everywhere, socially accepted, and culturally untouched. Its use isn’t questioned, it’s taken for granted. Complaints afterward are seen as individual, not systemic.

The Honest Explanation

Waste is moist, sticky, and uneven. Paper is dry, absorbent, and abrasive. It only removes loose residue and spreads the rest across the skin. In the process, friction builds up on a sensitive transitional area. That leads to micro-injuries, irritation, and leftover residue. No other part of the body would be treated this way.

What You Often Hear – and What’s True

“That’s good enough.”
It’s enough to reduce visible traces.

“That’s how it’s always been done.”
Long use is no substitute for being fit for purpose.

“Paper is hygienic.”
Paper doesn’t clean, it wipes.

“Alternatives are over the top.”
Unsuitable standards create workarounds.

The Takeaway

Toilet paper isn’t a well-thought-out hygiene tool. It’s a cultural compromise that fits poorly with biology.
