what causes a nose bleed?

Question

I woke up because it was hot in the room, to get some water and it started to bleed. My nose hasnt bled for years. And the room was no thotter than usuale. Does it have to do with the weather? Does anyone really know where the blood comes from?

Answer 1

Nosebleeds are caused by rupture of capillaries in the nasal lining. This happens if the air is too dry (as is often the case in winter), by trauma to the nose, or simply blowing your nose too hard. In the wintertime it helps to have a mist humidifier running in your room.

Answer 2

Weak blood vessels can cause a nose bleed especially if you have'nt been hit in it.People that suffer regularly can have their nose cortorised(can't spell) and this usually stops it.You could have had a nose bleed for all sorts of reasons,it doesn't seem worth worrying about unless it persists.
