Here's why:
* Evaporation is key: Nail polish dries through evaporation of the solvents in the polish.
* Breath is humid: When you breathe, you're exhaling warm, moist air. This moisture can actually slow down the evaporation process.
* Potential for dust and germs: Blowing on your nails can introduce dust particles or germs that can settle on the wet polish, affecting the smoothness and finish.
Better ways to dry your nail polish:
* Thin coats: Apply thin, even coats of polish. Thicker coats take much longer to dry.
* Quick-dry top coat: Use a quick-dry top coat specifically designed to speed up drying time.
* Drying drops or spray: These products often contain solvents that help the polish dry faster.
* Cold air: A stream of cool air from a fan or hair dryer (on the cool setting) can help speed up evaporation.
* Ice water bath: Dipping your nails in ice water for a few minutes can help set the polish. Be sure your nails are almost dry before trying this, and don't leave them in for too long.
* Patience: Sometimes, the best thing to do is simply wait and let the polish dry naturally.
