We have a natural curve in our neck called a lordosis which helps us distribute the weight of the head evenly down the spine. This is why it’s so important to maintain this natural neck curve in a resting position!
Pillow height
If the pillow is too high or low, this can increase the mechanical pressure to the cervical spine and may strain surrounding muscles of the neck and back
Incorrect neck positions
This may cause narrowing of the windpipe, leading to obstructed breathing and sometimes snoring which can all ultimately affect our sleep.
