The common causes of nosebleeds in diving are nose trauma, improper long posture, and barometric injuries.
1. Nose trauma: If the nose is bumped into the reef due to inexperience or dim vision during the dive, resulting in trauma to the nose, nosebleeds may occur.
2. Improper posture: If the head is always in a posture lower than the body during the dive, and because the underwater pressure is large, leading to expansion of blood vessels in the head to fill, there may be a rupture of blood vessels in the nasal cavity, and the phenomenon of nosebleed occurs.
3. Pressure injury: If the depth of diving is deeper, the pressure on the human body also increases, the blood pressure will also rise, resulting in the nasal cavity in the capillary rupture, can cause nosebleed.
If diving nosebleed, you should go to the hospital in time, under the guidance of the doctor for diagnosis and treatment, so as not to delay the condition.
