It's time to talk about something that often goes ignored on purpose - the 'yellow pillowcase'.
Now, if you don't have one, you likely know a friend, or have dated someone who has one and has held on to it for way too long, and to be honest, it can be off-putting.
Let's be real, nobody wants to lay their head to rest on something that looks dirty, and the truth behind why the pillow is this unfortunate colour actually makes it more disturbing.
It can be easy to ignore when you're quickly chucking a new pillowcase on, but this might just grab your attention.

Pillows usually turn yellow because of a buildup of sweat, which soaks in overnight and over time, permanently changing their colour.
Dribbling in your sleep is another cultript, as this can also change the colour of the pillow, as can the less-gross natural oils in your skin and hair.
These bodily substances are made up of salts, fats, and proteins, which turn yellow or brown with age.
Fabio Perrotta, director of buying at Dreams, previously told The Mirror: "The debate surrounding yellowing pillows is a hot topic, and it's important to consider both comfort and hygiene in this discussion. Pillows should ideally be replaced or thoroughly cleaned when they no longer provide the necessary support for a restful night's sleep.
"Yellowing of pillows can be attributed to several factors, including the accumulation of sweat, body oils, and dust mites. Interestingly, there are some other reasons why pillows may yellow, and men may be more susceptible due to their habits."
He outlined how men's grooming products, such as hair wax or styling products, can also transfer onto pillows, leading to discoloration.
"Additionally, hormonal differences may play a role; variations in sweat and skin oil composition can affect the rate of staining," the expert said.
However, Mattress Clarity Writer Celeste Parker told LADBible that your pillow being yellow doesn't necessarily mean it's unsafe to sleep on.
She advised: "If your pillow has minimal yellow stains, keeps your head and neck aligned, and feels comfortable, it is probably still fine to sleep on."
But, there does come a point when you should part ways with your yellow pillow - sorry if you've become attached!
The expert said: “Over time, pillows flatten, collect bacteria and dust, and become stained.
“When your pillow cannot fully support your head, smells like sweat or mildew after being cleaned, or mostly loses its original colour, it’s time to replace your pillow.”
She also stressed using a pillow protector, a good-quality pillowcase, and making sure to wash your pillow regularly.
Plus, if it's not yet 'gone overboard with the yellowing', you don't necessarily need to bin it, just chuck it in the washing machine and hope for the best. Good luck!
