There are no studies showing that looking at a cell phone has a risk of inducing a nosebleed. Nosebleeds can be caused by dry air, picking one’s nose too hard, or certain diseases.
A small amount of blood in a nosebleed may be caused by dry air or damage to the nasal mucous membrane caused by picking one’s nose too hard.
Larger amounts of blood or frequent recurrence, may be due to trauma, surgery, etc. to the nose, the anterior cranial fossa and the base of the cranial fossa injury caused by nosebleeds, inflammation of the nasal cavity and sinuses such as acute rhinitis, nasal septal diseases such as deviated septum, nasal tumors, blood disorders, such as hemophilia, leukemia, can also lead to frequent nosebleeds. There is no research that proves that looking at a cell phone has the risk of inducing a nosebleed.
Nosebleeds should be stopped in time, and timely consultation should be conducted under the guidance of a doctor. Avoid overexertion in daily life, take rest and drink plenty of water.
