A pillow that is too high or too low can cause strain on the neck and lead to discomfort or pain.A good rule of thumb is: If you use a pillow that keeps your spine in a neutral position, your muscles will still feel relaxed after 10 minutes.

This can vary for different sleep positions, for example, side sleepers may prefer a thicker pillow to keep the spine aligned, while stomach and back sleepers may prefer a thinner pillow.
