Why do pillows turn yellow sooner or later? It\u2019s something we all notice (and maybe pretend we haven\u2019t seen, and compensate for by popping on an extra pillowcase), but what\u2019s the story behind it? As you might expect, it\u2019s largely the result of what your pillow is exposed to during the night.\n
We\u2019re here to spill all the info on what\u2019s making your pillows turn yellow, as well as to explain how you can tell whether your pillow\u2019s a healthy sleep surface. Bottom line: if you\u2019ve had your pillow for more than a couple of years it\u2019s almost certainly past its best, and if it\u2019s covered in horrible yellow or brown patches as well, that\u2019s a sure sign that it\u2019s time for a sparkling new one; fortunately our best pillows guide can point you right at the best options available now.\n

Let\u2019s not get ahead of ourselves, though, because we\u2019re sure you want to know all the details about what causes those yellow stains on your pillows, and what you can do about them. And if you\u2019re more interested in getting rid of the stains than understanding how they happened (we can\u2019t say we blame you), head instead to our expert feature on how to wash a pillow and how often.\n
Why do pillows turn yellow?\n
There are a few possible causes behind yellow stains on a pillow, but the most likely culprit is sweat. You\u2019re probably not even aware of it but most us sweat a little in the night, and this can wick through your pillowcase and on to your pillow. It might not amount to much in one night, but over time it can build up and eventually cause yellow staining.\n
And it\u2019s not just sweat that makes your pillows turn yellow. Other forms of moisture such as your skin\u2019s natural oils, not to mention skin and hair product that you might not have washed off before bedtime, can all end up on your pillow and contribute to those unsightly yellow stains. And if that\u2019s not enough ghastly detail for you, take a look at our guide to what happens to your pillows when they aren\u2019t washed regularly.\n
It\u2019s the same with mattresses, so if yours is over seven years old and covered in stains (and shows other signs of wear and tear), consider upgrading. Our best mattress guide can help, and our roundup of the latest mattress sales can find you the best price when you buy.\n
Are pillows with yellow stains ok to sleep on?\n
\n
If your pillow is over two years old and covered in yellow and brown stains, we\u2019d recommend buying a new one. This is especially true if you haven\u2019t washed your pillow since buying it and don\u2019t use a pillow protector.\n
Chances are, the pillow has a build-up of other things besides sweat, oils and dead skin: dust mites might be lurking, as well as other allergens. Moisture from sweat and oil can also breed bacteria. And if your pillow is causing you neck pain or has lost its shape, then it\u2019s definitely time to replace it.\n
