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.

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.

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
