Researchers have found that earwax is a rich source of health information. Its chemical makeup is now being studied, which could potentially uncover new methods for diagnosing diseases such as Alzheimer’s, diabetes and cancer.
The scientific term for earwax is cerumen. It is a natural substance formed from secretions of two gland types in the outer ear canal, blending with hair, perspiration, debris, and other particles to reach a waxy consistency. Once produced in the ear canal, the substance is carried outward, adhering to skin cells as they move from the inner ear to the outer edge. Generated within the external ear passage, it serves to moisturize, cleanse, and shield the ears, acting as a defense against foreign particles.
Earwax varies based on genetic background. People of European or African heritage typically have wet earwax, which is of a yellow hue and is sticky. Whereas, East Asians have dry earwax, which is gray in color and non-sticky. Some individuals produce minimal earwax or none at all. Researchers are nearing the completion of studies to address this issue.
In recent years, earwax has transitioned from an overlooked biological material to a key subject in scientific research, especially for diagnostics. A prior study gathered earwax samples from individuals with and without cancer.
Scientists found 27 compounds in earwax that act as a unique signature for cancer detection, distinguishing cancer patients from healthy individuals with 100% accuracy. This new test could offer a fast, non-invasive, cost-effective, and highly precise method for diagnosing cancer. The researchers called the new method the Cerumenogram.
The versatility of earwax has astonished researchers with each study, and they are confident it will become a standard diagnostic tool with numerous applications for human and animal health.

When working to control your weight, you probably prioritize your diet. Yet an often-ignored element that’s vital is your sleep quality. Sleep deprivation affects millions. It is estimated that more than one-third of adults consistently get less than seven hours of sleep per night. How well you sleep impacts your body’s processes, influencing your behavior, blood sugar, and eating habits.
Do you struggle to fall asleep or stay asleep? A poor night's sleep often leaves your brain feeling foggy the next day. Ongoing sleep difficulties could have serious long-term effects on brain health. New research indicates that sleep is essential for various brain functions, including cognitive health.
Although research on the gut-brain axis has surged, the role of intestinal inflammation, such as IBD, in speeding up cognitive decline among individuals with existing dementia remains poorly understood. A recent study investigates the gut-brain axis, focusing on ways to enhance and better manage this condition.
