Your pillow is the place that comes in contact with your face every night, so it is important to pay attention to it. As time passes, your pillow may accumulate a lot of dirt, dust mites and other debris like oil and even dead skin cells. This is why you should make sure to wash your pillows regularly, and know when you should replace it so that you won’t have to suffer from other health problems like allergies or even breakouts.
Ideally, you should be changing your pillow once every two years. However, if you aren’t getting enough support, then you should change it even if the two years hasn’t passed yet. To lengthen the lifespan of your pillow, you can cover it with a protector, a waterproof one. You can also wash your pillow once a month, or take it out and expose it to sunlight to get rid of bacteria.
