What are the negative effects of sleeping without a pillow?
Your spine might twist into and remain at an incorrect angle without a pillow. This misalignment while you are sleep, can cause many aches and pains. You require a good cushion for proper neck support. Without one, you end up with an aching neck and stiff, painful shoulders. You can even toss and turn and have your sleep cycle broken. It can also intervene with your blood circulation. Not only should your pillow support your head, but it must guard your neck and assist in keeping your spine aligned straight.
When we say “right pillow,” we do not mean the same for everyone.
Are you a stomach sleeper? A side-sleeper? Or a back sleeper?
How you sleep will define the right pillow. The height of your shoulder and other parameters are very individual to a person and are all related to choosing the right pillow.
A quick side note here:
If you have an excellent mattress to your rescue, you may ditch the pillow for the back sleeper. In such a case, sleeping with a pillow might strain your neck and deform your sleep.
