Should you cover up a scrape or let it scab over?

It's generally advisable to cover a scrape with a sterile bandage to protect it from dirt and bacteria, which can prevent infection and promote healing. Keeping the scrape moist can also help it heal faster and reduce scabbing. However, if the scrape is minor and in a clean environment, letting it air out can also be beneficial once the risk of infection is low. Ultimately, the decision depends on the scrape's severity and location.
