What causes brake pads to yellow?
As you probably already suspect, the main and most likely cause is still sweat. After all, your pillow will gradually and irreversibly turn yellow every night. Body sweat penetrates the fibers of the pillow before rising to the surface. But although sweat remains the most suspected cause, other factors, such as saliva, also play a role.
The bodily fluids we excrete contribute to the yellowing of the pillow they absorb. Moreover, this discoloration is not just an aesthetic problem; it is a sign that bacteria and dust mites have nested in the fibers. And that is exactly where these parasites like to settle in virtual environments, which can cause conditions such as asthma and painful rhinitis.
