Pillows start fresh and bright, but it doesn’t take long for them to become discolored, with yellow spots that might leave you wondering if they’re dirty or just aged. This change, while common, can be a bit unsettling. So, what causes this yellowing, and how can you keep your pillows looking like new? Let’s explore the reasons behind pillow discoloration, ways to prevent it, and effective solutions for refreshing your bedding essentials.

The Science Behind the Yellow Stains

Even with regular pillowcase washing, pillows themselves absorb substances over time, leading to discoloration. The main culprits? Sweat, natural body oils, and skin products.

Sweating during sleep, especially in warm conditions, causes sweat to accumulate on pillows, leading to yellow stains. The average person loses 500-700 milliliters of sweat each night. Natural body oils, drool, makeup, and skincare products also contribute to discoloration over time. To prevent pillow yellowing, use protective pillow covers, wash pillowcases frequently, avoid oily products before bed, and keep your room cool. If yellowing occurs, pre-treat stains with baking soda and vinegar, wash with hot water, and dry thoroughly to maintain freshness. Replace pillows every 1-2 years for optimal comfort.
