Things in Our Bedrooms That Are Just as Bad for Sleep as a Cup of Coffee
Pillows should be replaced once every 1.5 years. Memory effect pillows live longer, up to 3 years. But if you are using a 5-6-year-old pillow, chances are your body doesn’t get enough support and your sleep isn’t as comfortable. To check if you need to replace a pillow, remove the pillowcase and look at the pillow attentively. Are there any sweat stains? Is it torn? Does it have a bad smell? Pillows collect dead skin cells, mold, ticks, and fungi. Over time, up to 1/2 of the pillow’s weight might consist of such unwanted components. And they can cause allergies that will impair your sleep.
