Dear friends, what pillow should I use in summer?

When choosing a pillow, you need to pay attention to the problems on the pillow, the height of the pillow, the hardness of the pillow and the width of the pillow. If it is used in summer, it should be filled with silkworm excrement, tea, buckwheat husk, rush, velvet antler and other materials. The imitation core with good air permeability and hygroscopicity and moderate hardness is better. Do not use functional pillows with calming and calming effects, which are not suitable for children. If you are afraid of sweating, buy two small pillows, linen, straw or pure cotton, and change one every day, which is easy to clean. .

1. Problem on the pillow: The cervical vertebra is located at the top of the human spine, wrapped around the neck, and consists of 7 vertebrae. The so-called physiological radian is the smooth and forward arc formed by these seven vertebrae, and the function of the pillow is to maintain this normal physiological curve. How to maintain a normal physiological curvature depends on whether you are really clear about the height, hardness and size of the pillow.

2. Height of pillow: This also varies from person to person. Although there is an old saying called "sit back and relax", the higher the pillow, the better. Because the pillow is too high, no matter what position you sleep in, it will affect your sleep. You can't keep the normal lordosis of the cervical spine, but it will go backwards, which will increase the burden on the cervical spine and may also cause stiff neck. Similarly, too low a pillow is not good, because too low a pillow will make the head congested and easily cause eyelid and facial edema.

Generally speaking, our sleeping positions are divided into supine, lateral and prone. It is best to choose a pillow that can keep the normal physiological curvature of the neck whether sleeping on your back or on your side. The height of the pillow for adults is 15 ~ 20cm when lying on their back, and about 20 ~ 15cm when sleeping on their side.

3. Hardness of the pillow: This is also suitable. Because of the excellent pillow, the contact area with the head decreases, the pressure increases, and the scalp will feel uncomfortable; On the other hand, the pillow is too soft to maintain a certain height, which will lead to excessive fatigue of the neck muscles, affect the smooth breathing, and is not conducive to sleep. Only by being a little softer without losing a certain hardness can we reduce the pressure between the pillow and the scalp, maintain uneven pressure, and let the blood circulate through the place with less pressure and maintain a certain height.

4. The width of the pillow: In general, it is better to be wider than the shoulder. Don't sleep with a pillow that is too small, because once you turn over, the pillow can't support your neck, and a pillow that is too small will also affect your sense of security when you sleep.
