Nosebleeds may be related to changes in body blood pressure, recent research suggests. A paper presented in the British Medical Journal certifies that nosebleeds occur mostly at breakfast time and then again at bedtime. The study was carried out in an Italian hospital, where nosebleed is considered a medical emergency, over a period of eight years.
The study revealed that most of the cases of epistaxis (nosebleed) are registered in the morning around eight o' clock after which the cases decline. Cases pick up again towards evening and a smaller peak is reached at around ten at night. These timings coincide closely with changes in blood pressure that follows a day-night cycle. Since the blood pressure is highest in the morning, it becomes a conducive time for nosebleeds.
The number of nosebleeds were lowest overnight and during the daytime. The pattern was found in all age groups regardless of sex or medical history of the patient.
