Do Scrapes Heal Faster Covered?

A handful of studies have found that when wounds are kept moist and covered, blood vessels regenerate faster and the number of cells that cause inflammation drop more rapidly than they do in wounds allowed to air out. It is best to keep a wound moist and covered for at least five days.

Do wounds need air to heal?

A: Airing out most wounds isn't beneficial because wounds need moisture to heal. Leaving a wound uncovered may dry out new surface cells, which can increase pain or slow the healing process. Most wound treatments or coverings promote a moist — but not overly wet — wound surface.

Is it better to keep a scrape covered or uncovered?

Leaving a wound uncovered helps it stay dry and helps it heal. If the wound isn't in an area that will get dirty or be rubbed by clothing, you don't have to cover it.
