Why do sunburns seem to "radiate" heat?
gpt
It's simply a matter of 1) increased bloodflow to the area and 2) various biochemical processes involved in the healing. When your body senses the damage from sunburn, it activates the immune response, which triggers increased blood in order to deliver white blood cells needed to fight potential infection and building blocks to repair the damage. This rush of blood by itself will increase the temperature. In addition the host of chemical reactions associated with the heavy cellular construction work needed to clear debris and repair the tissue will generate additional heat.
