Yes, pillow firmness is crucial. Side sleepers need a higher loft to fill the gap between the ear and shoulder. Too soft can cause neck misalignment and headaches, while too firm can strain the neck.
Cooling pillows can help if heat exacerbates your headaches. Bamboo covers, latex, and gel-infused foams wick heat. The Layla Kapok Pillow is a top cooling pick.
Replace a pillow every 1-2 years. Over time, materials lose support, leading to neck misalignment. Signs include waking with headaches or neck pain.
