ELI5: Why do burns blister and why do burn wounds remain warm long after the injury occurred?

Edit: Thanks, this is the first time I ever got more than 100 upvotes on anything. Ever.

Burn blisters occur when the second layer of the skin is damaged, they occur to protect the underlying skin layers from more damage and infection. You could see it as the bodys/skins natural bandage, so never pop them.

The skin remain  warm because of the increased blood in the area to repair and replace the damaged skin.
