where does wax in your ears come from
Earwax Earwax consists of shed skin cells, hair, and the secretions of the ceruminous and sebaceous glands of the outside ear canal.[2] Major components of earwax are long chain fatty acids, both saturated and unsaturated, alcohols, squalene, and cholesterol.[2] Excess or compacted cerumen can press against the eardrum or block the outside ear canal or hearing aids, potentially causing hearing loss.
Middle ear The middle ear is hollow. In a high-altitude environment or on diving into water, there will be a pressure difference between the middle ear and the outside environment. This pressure will pose a risk of bursting or otherwise damaging the tympanum if it is not relieved. If middle ear pressure remains low, the ear drum may become retracted into the middle ear <cite>. One of the functions of the Eustachian tubes that connect the middle ear to the nasopharynx is to help keep middle ear pressure the same as air pressure. The Eustachian tubes are normally pinched off at the nose end, to prevent being clogged with mucus, but they may be opened by lowering and protruding the jaw; this is why yawning or chewing helps relieve the pressure felt in the ears when on board an aircraft.
