However, I can tell you that dust under a pillow is usually a combination of things:
* Dead skin cells: We shed skin constantly, and some of those cells end up on our pillows.
* Hair: Both human and pet hair can accumulate on pillows.
* Fabric fibers: Pillowcases and bedding can shed fibers over time.
* Dust mites: These microscopic creatures live in dust and feed on dead skin cells.
* Dirt and debris: Particles from the air, such as pollen, dirt, and other small particles, can settle on pillows.
If you're concerned about dust under your pillow, you can try:
* Washing your pillowcases regularly: This will remove most of the loose dust and debris.
* Washing your pillows: Follow the manufacturer's instructions for cleaning your pillows.
* Using a dust mite-proof pillow cover: These covers can help to prevent dust mites from entering your pillow.
* Keeping your bedroom clean: Regularly dusting and vacuuming your bedroom can help to reduce the amount of dust in the air.
