One of the worst symptoms of the summer heat is the hot, sticky nights, which are common in countries like the UK, where air conditioning units aren't commonplace.
Our pillows really suffer as a result, due to the accumulation of moisture - think mass amounts of sweat, drool and even skincare products. All these can cause your pillows to turn a nasty yellow colour, and while there are ways of getting rid of the stains, the best way is prevention.
One of the things you can do to prevent the unsightly yellow stains is keep on top of your cleaning - and when it comes to bedding, many of us aren't cleaning it often enough.
