THE FACTS: The instructions for caring for fresh stitches are fairly universal: Keep the sutures clean and dry and avoid getting them wet for at least 48 hours. Doing so, the thinking goes, sharply reduces the rate of infection and improves healing.

Should you keep stitches dry or moist?

After 48 hours, surgical wounds can get wet without increasing the risk of infection. After this time, you can get your stitches wet briefly with a light spray (such as in the shower), but they should not be soaked (for example, in the bath). Make sure you pat the area dry afterwards.

Is it better to keep stitches covered or uncovered?

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.
