According to the guys from Supernatural (my husband got series boxset for Christmas so I'm unwittingly somewhat a paranormal/supernatural buff :/), the sun is not extremely harmful to vampires but is likened to nasty sunburn. This is why they prefer to sleep during the day.
Traditional vampire folklore (and Bram Stoker's Dracula) does not usually hold that sunlight is fatal to vampires though they are nocturnal. It is only with the film Nosferatu that the daylight is first depicted as deadly to vampires.
Is anyone intending to make any new years resolutions for 2011?
