Key Insights

• 🤵 Earwax, or cerumen, has been found in archaeological sites and serves as a grooming tool used by humans and other mammals.
• 🧑 The type of earwax one has can be determined by a single nucleotide change on a gene, which can track with a person's ancestry.
• 🧑‍🏭 Earwax acts as a lubricator, trapping debris and microbes, and contains proteins that fight bacterial infections.
• 🥹 Our ears have a natural process of self-cleaning, where new skin cells push old ones and the wax towards the opening of the ear canal.
• 😂 Attempting to remove earwax using tools like cotton swabs can lead to ear canal damage and should be avoided.
• 😂 Alternative practices like ear candling or coning are ineffective and can cause injuries or leave debris in the ears.
• 🔄 Over-the-counter eardrops can help soften earwax, and healthcare providers can safely remove blockages if necessary.
