A burn is a skin lesion due to contact or exposure of a dangerous agent, such as heat, cold, electricity, radiation from the sun or certain chemicals.

The human body tolerates temperatures of up to 40º C; above, the natural ability of the skin to regenerate is lost.

The degree of a burn is determined by its location in the body and by the depth at which it reaches the skin.

First Degree burns: only affect the most superficial layer of the skin, and are characterized by a reddening of the skin that hurts the contact, for example, when the person has had a prolonged exposure to the sun.
Second Degree burns: they are a little deeper, and their main characteristic is the appearance of blisters. The blisters are a system of defense against the burn: it protects against infections and, with the fluid they contain, moisturizes the wound and helps healing. These burns are very painful.
Third Degree Burns: in these burns we can see charred tissue, the nerve endings responsible for transmitting the pain are destroyed, hence it is said that third-degree burns do not hurt.

First aid steps for a person with burns:

Turn off the flames, remove the chemical from contact with the skin, all to reduce thermal aggression. To extinguish the flames, the person must be made to roll.
Look for other possible injuries such as hemorrhages, fractures … The most serious injury will always be treated first.
In first-degree burns, moisturizers and especially aloe vera are very beneficial.
Refresh the burned area: apply plenty of water (20-30 minutes) on the burned surface, avoiding it being too cold, because we can cause hypothermia. Previously, we must remove the burned clothes, jewelry and everything that keeps the heat.
Wrap the injury with gauze or clean cloths, moistened with water. The bandage must be loose.

There are certain actions that in no case should be carried out, since they would be harmful for the patient:

Apply ointments, creams, toothpaste on the burn. Just water.
Cool the patient too much, only the burned area.
Give water, alcohol, analgesics, orally.
Break the blisters, because the liquid they contain protects against possible infection. By breaking them open a door for the entry of germs.
Take off clothes or any other item that is stuck to the skin.
Leave the victim alone. In case you have to go to ask for help, we will take it with us, as long as your injuries allow it.
Turn off the person’s flames with water. They should always be turned off by rolling or covering them.
