There’s no fire in the sun. Fire is some material oxidizing, and that’s not what’s happening (or at least not in relevant amounts). What creates the radiation is nuclear fusion.
The heat could dry out your skin, which, if I’m not mistaken, is essentially what a burn is. However, as the other person noted, a sunburn is damage from radiation, not heat. So I think you could stretch the common definition of a burn to call heat induced dry skin a burn but calling it a sunburn would not be accurate.
@[email protected] If you sit at a magnesium fire, it burns at 3300K, which is hot enough to produce sizeable ultraviolet rays. So you can get your sunburn from that, damaging the DNA in whatever of your remaining cells have not been melted away by heat.
Note to self - Don’t sit near a magnesium fireplace if you don’t want to tan your bones, which are now exposed due to the flesh getting melted off by the said fireplace.
“ball of fire”
Haha, no no. You threw down with a gigantic source of cell destroying radiation. The fire did no harm.

Hypothetically speaking, will you get sunburnt if you sit near a fire all day?

Thanks. I completely forgot that the standard suntan or sunburn is caused by UV rays. A fireplace doesn’t create UV rays.

Maybe! https://en.wikipedia.org/wiki/Erythema_ab_igne
Why exactly do you think there is UV radiation coming from the sun?
Because the spectrometer says so, mainly. Why?
