WHY DO WE PUT BAND AID ON OUR SCRATCHES AND BRUISES?

We put Band-Aids on scratches and bruises to protect the wound from dirt and bacteria, which can lead to infection. They also help keep the area moist, which can promote faster healing. Additionally, Band-Aids provide a physical barrier that can reduce pain and irritation from friction or exposure to the elements. Overall, they aid in the healing process while offering comfort and protection.
