what can cause burns
Is there a different between burns and scald
passage
The skin is an essential part of your body and is its largest organ.Your skin acts as a barrier against disease,toxins,and the sun's rays.It also helps control your body temperature,prevents your body from losing too much water,warns you when things are too hot or cold,and gives you your sense of touch. As you can imagine,getting burnt can lead to very serious injuries. The first and most important step in the treatment of burns is giving first aid.

the injured areas is a bad idea, as it will keep the heat in the
wounds and may cause infection.
