Wondering if it's time for a new pillow? There's a simple trick to find out: the "bend test."
Here’s how you do it: fold your pillow in half and then release it. If it springs back to its original shape quickly, it's still good. But if it stays folded or slowly returns to shape, it's a sign to replace it.
This lack of resilience means your pillow can't support your head and neck properly anymore, which is crucial for a good night's sleep. And keep this in mind – the Asthma and Allergy Foundation suggests updating your pillows every two years to maintain optimal comfort and health.
