How Often to Replace Pillows: A Complete Guide to Pillow Hygiene


Pillows, faithful companions at the end of a long day, are more than just a resting place for weary heads. They offer comfort and support for the neck and spine and contribute to a good night’s sleep. However, like all other items in the household, pillows also have a lifespan and must be replaced regularly. Not doing so may decrease comfort, compromise hygiene, and potential health risks.

This guide will explore the importance of replacing pillows, how often to do it, and tips to extend their lifespan, ensuring your sleep environment remains healthy and conducive to restful sleep.
