* "Outdoor nails" likely refer to your fingernails. These nails are meant to protect your fingertips and shouldn't be trimmed shorter than the end of your finger.
* Trimming fingernails too short can lead to problems:
* Ingrown nails: This is when the edge of the nail grows into the skin, causing pain and possible infection.
* Nail damage: Trimming nails too short can damage the nail matrix, which is the part of the nail responsible for growth.
* Increased risk of infection: When the nail is cut too short, it leaves the skin more exposed to bacteria.
Instead of trimming, consider:
* Filing: Use a nail file to smooth out rough edges and give your nails a nice shape.
* Keeping your nails clean and dry: This is the best way to prevent infections.
If you're having trouble with your fingernails, it's always best to consult with a dermatologist or podiatrist.
