Why does sunburnt skin remain hot to the touch even days after the burn has occurred?

Your body is repairing itself. Many cells DNA could have been damaged, so your cells need extra nutrients to repair the damage, make new cells, and make more melanin. That means extra blood goes to the area. The redness itself is capillaries expanding near the surface of the skin. It's not residual heat leftover from the sun.
