Your pillow is more than a bedroom accessory, it’s your gateway to a good night’s rest. So how can you be sure it’s doing the best it can? And how often should you change it?

Every 6 months.

For polyester pillows, it’s recommended that you swap out your oldie with newbie twice a year. However, other pillows, like memory foam, can last up to 3 years. Just make sure you check the product’s expiry date.

But why should we swap out our pillows so often? Well, there are two big reasons that come up: hygiene and support.

Why do we need to change our pillows?


If you’re getting the recommended hours of sleep each night, that’s 2,920 hours (or over 120 days) where your head is making contact with your favourite ball of fluff. During this time, dead skin cells, body oils, and other dirt and fluids migrate from your body to your pillow. Especially during hot summers, when we sweat more than we’d like to. Ew.

So what does this mean for you? Well, oils, dust and dirt can contribute to blocked pores, while old pillows are also the perfect environment for dust mites. These critters are friendly neighbours, but their by-product (from a diet of dead skin) can be a real issue if you suffer from allergies or asthma – and even if you don’t, you could be increasing your chances of colds, acne, and skin irritations.

But even swapping out your pillow isn’t enough. You must ensure that you’re washing it regularly and following your pillow’s care instructions.

Top tip: Wash your pillow cases with hot water, vinegar and hydrogen peroxide to freshen, whiten, and disinfect them.


Even mountains wear away and change shape over time, so imagine what’s going on inside your soft pillow. Polyester has always been a popular choice for pillows, but its micro fillings do break down and warp. This leads to a lack of support and the formation of lumps – an unwanted obstacle to a comfortable sleep.

This change happens over a long period of time, so it’s hard to notice when your pillow doesn’t do the job it did months ago. However, you can test your polyester pillow with the fold test. Simply fold it in half and let go. A good pillow will spring back into its original shape. If it doesn’t? It needs to go.

This timeline of support is different with other types of pillows, like memory foam, which often come with guarantees of several years.

Top tip: Make sure you’re regularly changing your kids’ pillows, too. Their growing bodies need constant and effective support.
