One of the main benefits of cervical pillow is that it can help to relieve neck pain. When you lie down on your bed and try to sleep on your back, your neck will often end up in an uncomfortable position. This is because when you rest your head on the pillow, your neck will be in a much more comfortable position. The cervical pillow also helps to increase blood flow to your head and neck, which can help to relieve any pain or discomfort that you may be experiencing.
