Watch out for vasoconstriction in extremely cold weather causing deafness

“Sudden deafness” is also called “sudden deafness” or “sudden deafness”, which is a kind of sensorineural deafness of unknown origin that occurs suddenly.

Deafness often occurs instantaneously, mostly in one ear, and occasionally in both ears at the same time or successively.There are also some patients who had previous viral infections, manifested as sudden sensorineural hearing loss, onset for several hours or days, accompanied by tinnitus, and then hearing loss.

The cause of deafness is unclear.Generally speaking, the onset of deafness is often related to mental stress, fatigue and some diseases, the most common being hyperlipidemia and hypertension.

Otorhinolaryngology doctors often refer to sudden deafness as “minor ear stroke” or “ear stroke”.The principle is that when the patient’s blood vessels contract cold, it will cause blood vessel embolism and deafness.This winter is particularly cold. The blood vessels contract when cold is more likely to cause deafness. Patients with a history of hyperlipidemia and hypertension should be careful.Once high blood pressure is not well controlled, after days of exertion, it will often induce inner ear vasospasm or arteriosclerosis, and deafness will follow after insufficient blood supply.

To prevent sudden deafness, Chinese products give the following suggestions——

First of all, control high blood pressure and hyperlipidemia.The second is to prevent cervical spondylosis. The dislocation of the small joints of the cervical spine will stimulate and compress the vertebral artery and cause vertebral artery spasm. At the same time, it will cause the blood flow of the internal auditory artery to decrease, and it will also induce deafness.The weather is cold recently, you can apply a hot water bottle to your neck to improve blood circulation in the cervical spine.

Secondly, soothe emotions.The blood circulation in the ears is related to the influence of emotions. Excessive pressure can easily cause vasospasm.Eat more foods rich in vitamin A and carotene in your life to increase inner ear nutrition.Eat less spicy food, drink less coffee and drink hard alcohol.Don’t be too tired in work and life.

Finally, protect the ears.After listening to MP3 and other music players for half an hour to an hour, take a break.Headphones are best to choose a head-mounted type.When listening to music, don’t amplify the low-frequency sound too much.Low-frequency sound damages the hair cells in the cochlea greatly.The music volume must also be controlled within 80 decibels.If the working environment is very noisy and the noise is serious, it is recommended to prepare a pair of earplugs with good sound insulation effect to protect your hearing.

The incidence of deafness is relatively high in the young and middle-aged population, but it has not attracted enough attention. Many people miss the best treatment time.

Early deafness is reversible.Therefore, the treatment of sudden deafness should be as early as fire fighting, and timely treatment within 3 days after the onset of illness. About 80% of patients can restore hearing.Within one week of the onset of the disease, it can be treated by nourishing the nerves, improving microcirculation, using drugs that dilate blood vessels, and injecting drugs into the ear tympanic cavity. The effect is relatively good.If the course of the disease exceeds one month, the inner ear damage is irreversible, and the possibility of hearing recovery is very small.

What needs to be vigilant is that “ear stroke” is often a precursor to “brain stroke”.Once symptoms such as tinnitus and hearing loss occur, you must seek medical attention as soon as possible to check for deafness.
