Why do children suddenly have nosebleeds in summer?

Children rarely have nosebleeds before the age of two. This is because the capillaries in the child's nasal cavity are not yet fully developed. However, as the baby grows older, the capillaries in the nasal cavity will increase, and nosebleeds will become more likely to occur, especially in the summer when the weather is very hot and the air humidity is relatively high. Children often have sudden nosebleeds for no apparent reason. The reasons behind this are introduced in detail below.

Why do children suddenly have nosebleeds in summer?

There are many reasons for nosebleeds, but about half of people cannot find the cause. The tiny blood vessels in the nasal mucosa are densely distributed, very sensitive and fragile, and can easily rupture and cause bleeding.

There are many reasons for nosebleeds, including nasal trauma, dry scabs on the mucous membrane, damage from acid and alkali foreign bodies, excessive sun exposure, excessive drinking, etc. Frequent nosebleeds are a complication of the cardiovascular system, internal organs, various infections, blood diseases and other diseases.

Nosebleeds in children are often a sign of influenza or acute respiratory disease. If purulent discharge from the nose precedes the nosebleed, then a foreign body may be the primary cause. At this time, it can only be removed by a doctor.

As we all know, about 5 kilograms of blood circulates in the body of an adult. Losing 200-400 ml of blood at a time can be recovered quickly, and the human body will not actually feel it. Nosebleeds in patients with hypertension often lead to anemia.

Most nose bleeds occur in the blood vessels in the front of the nose. How should we help people with nosebleeds and what measures should we take? First, the patient needs to sit down with his head straight and his collar and belt loosened. In order to stop nose bleeding, some people tilt their head back. This is a wrong practice because when the blood flows into the throat, people will swallow, which will increase the blood flow. In addition, the blood flowing in through the pharynx can irritate the stomach and cause vomiting. This may also cause increased bleeding. If the blood is swallowed, it will be impossible to accurately determine the amount of bleeding, which is not conducive to diagnosis.

You should also not tilt your head forward too low. Usually, you can put a small cotton plug into the nostrils and clamp the sides of the nose for 3-5 minutes, and the bleeding will stop smoothly. If possible, it is best to dip the tampon in a 3% hydrogen peroxide solution, which can enhance blood clotting.

As we all know, blood vessels constrict when we are cold. So you can stick cotton, towel or handkerchief soaked in cold water on the bridge of your nose. Within an hour, you can place an ice pack on the bridge of your nose for 1-2 minutes, every 2-3 minutes.

After the nosebleed stops, do not remove the tampon from the nose immediately. It can be kept in for 2-3 hours if the patient is not asleep. The tampon inserted by children can be removed after 20-30 minutes.

If pinching the sides of the nose or stuffing it with cotton does not help within half an hour, you should seek emergency treatment immediately. Be aware that this could be bleeding from a blood vessel deep inside the nose.
