Should bandaging or leave open wounds exposed to the air?

I remember when I was a child, I was often told to let the wound be exposed to fresh air, especially if it was a new wound.

I have no knowledge and no need to argue about this concept, so I agree that it is reasonable to let the wound breathe some fresh air. Interestingly, after many years, I still see many people exposed to the air to be able to heal faster.

But, when you go to the hospital with a new wound, one of the first things the nurse does is clean the wound and bandage it. Why do they do that?

If a wound is exposed to the air will be very good and promote healing, why do doctors recommend covering the wound with gauze?

Well, let me tell you that leaving a wound in contact with the air helps to heal faster is a misconception . Except for bruises or small scratches, it is best to always cover the wounds.

The human body is an interesting and effective mechanism that is made up of biological parts. It has different methods for dealing with each type of injury, one of the most common ways that the human body responds to a wound is scab formation.

A typical scale.

The formation of scabs begins as soon as you are injured and the wound starts to bleed. Special blood cells called platelets treat as soon as they notice that there is "intrusion" in your skin. Platelets stick together like glue at the wound site (such as cuts, scratches or bruises) and form blood clots.

This blood clot acts as a bio-protective bandage on the wound and prevents further bleeding. If the injured part of the skin (and blood clot) is not bandaged, the blood clot dries and hardens, forming scales. We tend to think that forming a scale is a sign of recovery.

Scales are the body's natural protective layer against germs, but in fact, that is not the best way to heal wounds. Scales hinder the healing process by erecting a dead cell barrier. Healthy skin cells must work at the bottom of dead cells to form new tissue and support the healing process.

So turned out to be a wound (except for small cuts and scratches, no bleeding) exposure to "air" is always a bad idea. Bandaging the wound will always be better especially if it is a bleeding wound.

Why is bandaging important?

If a new wound is bandaged, it will keep skin cells from drying out and forming scales, which minimizes the risk of scarring at the site.Bandaging the wound is a very good thing, which helps to moisturize, promote better skin healing.

A good bandage wound is not infected.

Bandaging also significantly reduces the risk of infection, because it prevents germs, dirt and water from contacting the wound. This is a good thing, because if germs, dirt and other unwanted things come in contact with the injury, you can get an infection.

Moreover, open wounds that are not protected from other injuries will make the condition worse. In other words, if the wound is not bandaged, the scales may be scratched or ripped apart and are also at risk of re-injury.

On the contrary, bandages make the wound more comfortable. It also protects against re-injury.

Abstract at best need to bandage your wound, as this will help protect them and promote healing.
