5. You Can’t Remember Buying Your Pillow

Not only can an old pillow cause neck and back problems if they are wearing thin, but old pillows are full of dust mites, no matter how often you wash your pillowcase! This is pretty gross to think about, but the reason for dust mite disturbance is much deeper. Dust mites are one of the most common allergens, so if you are susceptible to allergies, make sure to change your pillow often! The beginnings of an allergy attack may be causing you to have trouble falling asleep. You should clean your pillow regularly, and replace it about once a year.
