Discoloration of bedding, specifically the acquisition of a yellowish hue in pillows, is a common observation. This phenomenon primarily stems from the accumulation of bodily fluids and environmental factors over time. Perspiration, saliva, natural skin oils, and even hair products contribute to staining that gradually permeates the fabric and filling material.
Addressing this discoloration is crucial for maintaining hygienic sleep conditions and prolonging the lifespan of bedding. While seemingly cosmetic, these stains can harbor dust mites, allergens, and bacteria, potentially impacting respiratory health and skin conditions. Historically, preventative measures such as pillow protectors and regular washing have been employed to mitigate this process.
