✱ 1 – Sleeping On Your Stomach Or Sides Causes Headaches
You already know that your muscles in your neck are strained when you sleep on your stomach or sides. Therefore, that will also strain the muscles around your head which means you could wake up having a bad headache. And if this happens day after day, then you will have to try sleeping on your back.
It is also important to make sure the pillow you are sleeping on is supportive of your neck and head. Be sure to change your mattress every 7 years as well. Sleeping on a mattress that is sunken in will only be less supportive of your body over time.
