The weather is hot, how is the nosebleed? What should I do if the weather is hot and bloody?

1 What's the heat flow and nosebleeds in the weather? Lack of water in nasal cavity. Summer is hot and dry, and the temperature difference between day and night changes greatly, which makes the liquid secreted by nasal mucosa evaporate quickly, and the nasal cavity is dry and itchy due to lack of water, and it is easy to bleed.

Temperature instability Due to the temperature instability in a day, nasal capillaries repeatedly expand and contract to adapt to the change of external temperature, which leads to bleeding.

Qi and blood go up against heat. If people are in a bad mood and have a bad rest, it will lead to qi and blood going against the wind, resulting in nosebleeds. In addition, drinking alcohol and eating spicy food in summer may also lead to lung heat, and lung heat enters the nasal cavity, causing telangiectasia and rupture, leading to nosebleeds.

External stimuli, such as frequent entry into air-conditioned rooms in summer, can cause nasal itching when hot and cold alternate. At this time, if you scratch, it is easy to rupture the capillaries in the nasal cavity, causing nosebleeds; Also, if you blow your nose often, it is easy to stimulate capillaries and cause blood vessels to rupture.

Nasal inflammation Dry rhinitis, atrophic rhinitis, acute rhinitis and acute maxillary sinusitis are common causes of epistaxis. Also, if rhinitis is serious, when sneezing, it will lead to bleeding because of capillary rupture.

Hypertension and arteriosclerosis Hypertension and arteriosclerosis are important causes of nosebleeds in middle-aged and elderly people, and arteriosclerosis is the pathological basis of nosebleeds. Elevated blood pressure, especially in constipation, overexertion or emotional excitement, will lead to rupture of nasal blood vessels, leading to nosebleeds.

Diseases such as elevated venous pressure, emphysema, pulmonary heart disease and mitral stenosis can lead to superior vena cava hypertension; The nasal cavity and nasopharyngeal vein of such patients are often swollen and congested, which is easy to rupture and bleed, causing nosebleeds.

Platelet abnormality We know that the function of platelets is mainly coagulation. If the number or function of platelets is abnormal, such as primary thrombocytopenic purpura and secondary thrombocytopenia. It will lead to nosebleeds, especially the stimulation of high temperature in summer, which will be difficult to stop.

Hemophilia patients with disorder of coagulation factors will bleed for no reason due to lack of coagulation factors, and once bleeding, it is difficult to stop bleeding. Vitamin k can promote blood coagulation, and it is easy to have nosebleeds if it is lacking.

Such as hereditary hemorrhagic telangiectasia, allergic purpura and drug-induced vascular purpura. , there will be bleeding under the skin of the whole body, and it is easy to have nosebleeds.

How to deal with nosebleeds caused by heat flow in 2 days? If there is less bleeding, press both nasal alars with index finger and thumb for 5 ~ 10 minutes. At the same time, you can also use an ice pack or a wet towel to compress your nose. If there is too much bleeding, you have to dip absorbent cotton or clean cotton and gauze in water, and then slowly put wet cotton into your nose. It is better to use Notoginseng Radix and Yunnan Baiyao dipped in cotton to stop bleeding.

Tip:

Don't look back when there is a lot of nosebleeds, so as to avoid blood entering the respiratory tract by mistake. It is best not to blow your nose within one day after a nosebleed. Because after nosebleeds, blood clots will form scabs after blood coagulation. At this time, if you dig your nose, it may lead to the peeling of scab skin and the recurrence of nosebleed.
