How to prevent deafness and hearing loss?
Prevent trauma and frostbite in the auricle
In cold weather, especially in outdoor activities, wear cotton or wool earmuffs. If it has been frostbittened, remember not to use a hot water bottle or a hot towel for rapid temperature rise. Apply a clean palm of your hand to gently massage the auricle, and avoid using a forceful poke to prevent auricle necrosis. If frostbite has already occurred, it can be applied with a frostbite cream. If there is ulcer or necrosis, antibiotics can be used to prevent infection.
Correct bad habits
The presence of sputum in the human ear canal is a normal physiological phenomenon, and a small amount of sputum sputum will be discharged by vibration and jaw movement. Do not dig ears often, otherwise it will cause damage to the wall of the ear canal. Especially in the elderly, the elasticity and toughness of the auricle are reduced, and the sputum is easy to concentrate and harden. If it is not noticed, it will damage the external auditory canal. The right way: If the ear is itchy, use cotton dipped75%Alcohol wipe, not only itching can be sterilized; if it is strong, it should be cleaned up in a regular hospital with special tools. If it becomes hard, it should be softened with a syrup.
Do a good job in nasal health and train the correct nose
The middle ear includes the tympanic cavity, eustachian tube, sinus sinus, and mastoid. The Eustachian tube is the only ventilation tube that communicates the tympanic cavity and the nasopharyngeal cavity. When the person swallows and rubs the nose, the eustachian tube will open instantly. If bacteria or virus enters the middle ear through the eustachian tube, it will cause otitis media and cause hearing loss. If the nose is blocked, available0.5%Ephedrine saline nasal drops. The correct method of rubbing nose: use your fingers to block one side of the nostrils first, and the other side of the nasal secretions, and then press the other side. Do not pinch the left and right nostrils at the same time, otherwise nasal secretions may enter the middle ear and cause otitis media.

Pay attention to the influence of instrument noise
For example, the sounds of instruments such as cymbals and erhus can produce very good music, but if you immerse them for a long time and the sound is too strong, it will cause damage to the ears.
Seek medical attention in time to protect hearing health
Sometimes sudden deafness is caused by problems such as stress and nervousness. At this time, you should seek medical advice promptly. If it is delayed, there is a possibility of permanent hearing loss.
