Why do burns hurt so much and why does it vary depending on the type (wet/dry). Also, what classifies the 1st/2nd/3rd degree?
In: Biology
There are 3 basic layers of skin: the epidermis on the outside, dermis in the middle, and then subcutaneous tissue.
1st degree: damage to only the outer layer/epidermis, no blisters
2nd degree: damage to the epidermis and part of the dermis, blisters appear
3rd degree: epidermis and dermis are completely destroyed, subcutaneous tissue may also be damaged.
There are lots of pain receptors closer to the surface and less when you get deeper, so most shallower burns hurt a whole lot. Deeper burns like deep second and third degree burns may actually not be painful because the pain receptors are destroyed. Don’t know much about wet/dry.
