Time for a new pillow?

This may sound obvious - If your pillow is too tall, it may impact the quality of your sleep.

Less obvious – How tall is too tall? Not very according to a Japanese study discussed in a recent Bloomberg article. Two excerpts from the study:

“Even a pillow that’s 2 centimeters (1 inch) too high can reduce sleep quality by causing shoulder and back strain”

“Those using an ill-fitting pillow were 2.8 times more likely to suffer back pain and 1.5 times more likely to experience tiredness”
