dear, Sleep deprivation can result in- 1) day time sleepiness 2) dizzy mind in mornings 3) poor concentration. 4) bad mood, irritability, poor memory problems 5) in a long term it can lead to cardiac problems however, bloody nose is not related due to sleep disturbances. Its probably an episode of epistaxis. I would like to know, for how many times have you had such episodes before? treatment: just a firm pinch clamp on nose with a thumb and index finger will stop the bleeding. If the bleeding still persist, a small procedure of stuffing the nose with a gauge piece is done, it is to be done only by an ent specialist. As of now there appears nothing to be majorly concerned about. thank you.
