Are you waking up sore and achy, or feeling worse than when you went to bed? You may not be getting the posture support that you need while sleeping. Most people feel soreness or stiffness in the neck, back, and shoulders when they wake up. If this is the case for you, you may not have the right type of pillow. There are specific pillows that are curved to aid posture; they keep the head and neck aligned properly while resting. Many people have found better support from memory foam pillows, which also help to maintain balance and alignment while sleeping. They are also less expensive than luxurious down pillows. It is often agreed that sleeping on your back is the best position, however, if you must sleep on your side, try to have a supportive pillow between your knees to keep the spine aligned. If possible, avoid sleeping on your stomach; this is considered to be the worst position for your back.
