Choose a suitable pillow. Generally a fist high pillow for supine and one and a half fist high pillow for side sleepers, about 10 cm, should not be too high. Pillow filling should be appropriate to maintain a certain amount of firmness and elasticity.
Pillows with too much elasticity tend to cause fatigue and injury to the neck muscles.
Prevent trauma and fallen pillows. One is to avoid strenuous movements of the head and neck.
Strengthen the exercise of the neck. Strengthening neck exercises can prevent and delay the onset and development of cervical spine disorders.
