The skin is an essential part of your body and its largest organ.You have three layers of skin which act as a barrier against disease,poisons and the sun's harmful rays.The functions of your skin are also very complex:it keeps you warm or cool; it prevents your body from losing too much water; it is where you feel cold,heat or pain and it gives you your sense of touch.So as you can imagine,if your skin gets burned it can be very serious.First aid is a very important first step in the treatment of bums.
Causes of burns
You can get burned by a variety of things:hot liquids,steam,fire,radiation (by being close to high heat or fire,etc),the sun,electricity or chemicals.
Types of burns
There are three types of burns.Burns are called first,second or third degree burns,depending on
which layers of the skin are burned.
◎ First degree burns These affect only the top layer of the skin.These burns are not serious and should feel better within a day or two.Examples include mild sunburn and burns caused by touching a hot pan,stove or iron for a mordent.
◎ Second degree burns These affect both the top and the second layer of the skin.These bums are serious and take a few weeks to heal.Examples include severe sunburn and bums caused by hot liquids.
◎ Third degree burns These affect all three layers of the skin and any tissue and organs under the skin.Examples include burns caused by electric shocks,burning clothes,or severe petrol fires.These burns cause very severe injuries and the victim must go to hospital at once.
