1, the correct use of square and round neck pillows

Before using the round neck pillow, gently pat the middle area of the round neck pillow with your hands, so that the filler in the pillow can be relatively loose, thus increasing its fluidity and making the pillow fit the curvature of cervical vertebra more naturally.

First, put the round pillow under the neck and adjust the position so that the pillow fits the radian of the neck. Under the gravity of the head and shoulders, the cervical vertebra can form an arc tension along the surface of the round pillow. After stretching with a round pillow, add a square pillow, adjust to a comfortable position and sleep on your back. Lying on your back can keep the cervical spine stretched. If the cervical spondylosis is serious, only use the square pillow when sleeping, so as not to hurt the cervical vertebra if the pillow is too high.

2, the correct use of rectangular neck pillow

Rectangular neck pillow is a kind of neck pillow. When people lie on their backs, the center of the neck pillow is sunken, and the back of the head provides a background of 3-4cm, which can support the radian formed by the head, cervical vertebrae and shoulders and align the cervical vertebrae. If the neck area fits evenly, it can relax the muscles well. Before going to bed, the cervical vertebra clings to the higher side of the rectangular neck pillow, so that the curve of the pillow fits the neck and shoulders.

3. Correct use of U-shaped neck pillow

The curve design of U-shaped neck pillow with high pillow edge and low middle can fix the natural curve of the head, flatten the viewing angle, and the protruding part supports the weight of the head and neck. Suitable for putting books, wrap around your neck and cling to your shoulders when resting. You can also cross the two ends of the U-shaped pillow on your back to reduce the pressure on your back.
