Ear candling is the practice of inserting a hollow candle in a person's ear and then lighting the candle to let the wax substance drip into the ear canal. When the wax substance is removed, it’s believed to remove a mixture of ear wax and debris out of the ear canal.
Research shows that ear candling is ineffective at removing ear wax. Ear candling could potentially push the ear wax deeper into the ear canal. Other risks include candle wax getting stuck in the ear canal, and burns to the face, the ear canal, the eardrum, or the middle ear cavity.
If you develop ear wax blockage, please consult with your hearing professional or your doctor on safer and effective methods to remove the wax. They may refer you to an Ear, Nose and Throat specialist depending on the condition.
Please keep in mind that producing ear wax is healthy and natural. It helps protect your ears from any debris or foreign objects.
