A year ago I bought a memory foam pillow after reading positive reviews about it in Amazon.
At the beginning it felt hard, but I kept it, thinking that I’d get used to it. And I actually got used to it. Except that my sleep quality was deteriorating slowly without me noticing.
The pillow lead to a “hidden” neck pain that I was feeling all the time. During the last previous months my sleep was horrible, I’d randomly wake up a lot of times during the night.
Two weeks ago I thought about ditching the pillow. The results were magical : I’ve never felt having a better sleep during the past year, and my neck pain started disappearing.
I’m still surprised how a whole year has passed before I suspected that the pillow might be the cause.
