It wasn’t until a recent bout of neck and shoulder stiffness (brought about by long hours at my desk and made worse by improper sleep posture) highlighted to me the importance of having the right pillow. Not to mention the time
It came to my attention that, while we may flip our mattresses every six months or so and (try to) replace them when the time comes, pillows are often overlooked when it’s time for replacement. Pillows age and wear over time and lose their firmness and along with that (and most importantly) their ability to adequately support your neck and spine.
I can now say from personal experience that my neck issues could have been resolved much quicker had I changed out my pillows. I eventually discovered that pillows should be replaced every two to three years or when you start to feel a loss of support when you lay your head down.
