A pillow starts out white and bright. However, after a few months of use, it takes on a yellowish tint that can seem unhygienic. Are these stains due to dirt, wear, or something else?
The answer is simple: this yellowing is caused by the accumulation of perspiration, body oils, saliva, and skincare product residue. Even with clean pillowcases, these substances gradually seep into the pillow, leading to discoloration.
Let’s take a closer look at the main causes of this phenomenon.
The main causes of yellowing pillows
Sweating no
turn
During the night, the body naturally releases sweat, even if you don’t realize it. On average, a person loses between 500 and 700 ml of perspiration per night . This moisture soaks into the fabrics and leaves yellow marks over time.
Body oils
The skin constantly produces natural oils that are deposited on the bedding. Unlike perspiration, these oils are more greasy and harder to remove. Over time, they penetrate the pillow and contribute to its yellowing.
