Does the band-aid have an effect on the healing of minor wounds?

In fact, it has always been thought that the role of band-aid is to keep the wound from direct contact with air and water, which is more convenient, but it has no direct benefit to the healing of small wounds. Let me briefly talk about it.

I believe that anyone who has used a band-aid has found such a situation. The band-aid has been used for more than a day, and the wound will be ugly when it is torn off. Although it will still be used, its wound will turn white. In fact, it plays a role in hemostasis and isolation, but it will heal slowly when applied.

As a do-it-yourself foodie, I often cut my hand, sometimes there is no band-aid at home, and some small wounds are useless. In contrast, the wound heals faster than using a band-aid. After using the band-aid, a dead skin will definitely be removed, but it will not work if it is useless, especially if the package is too tight, the peeling area of the dead skin will appear.

However, people who work in an infectious environment should stick a band-aid when they are injured, because if they don't, even a small wound may be infected with tetanus, and then they will be in big trouble. Although it can't heal faster, its isolation and mild anesthesia effect will be of great help to continue to do things after injury. People who have used it will find that the wound will be less painful after sticking a band-aid.

There are two reasons for this. One is not directly facing the wound, so the brain's response to the wound is weak, so it feels less painful. After watching some videos, I feel that "it hurts to watch" is a truth; Second, a little anesthetic in the band-aid will relieve the pain. In addition, when using a band-aid, you should also choose a brand. Some medicine is better. Some people in some places will have edema in their wounds. Persistence in a certain country is better than no persistence. I don't know what the principle is.
