Pillow is an indispensable substance when sleeping. The quality of pillows will have a certain impact on the quality of sleep. The hardness and height of the pillow need to be selected. A suitable pillow helps you sleep. It is very hot in summer. When choosing pillows, try to choose some pillows with good heat dissipation. So what pillow should I use to sleep in summer? What pillow is used for sleeping in summer?

1. What pillows are cold in summer?

The filler determines the hardness and efficacy of the pillow. A suitable pillow should have moderate hardness and a little elasticity. Now there are all kinds of pillow cores on the market, such as mung bean skin, cassia seed, silkworm excrement, lavender and so on. Next, let's look at the functions of these different kinds of pillow cores.

1, cassia seed. Cassia seed is slightly cold and slightly grassy. It smells like sleeping in the green grass, and it can massage the acupuncture points on the head and neck. In addition, cassia seed has unique coolness, which is particularly comfortable to use in summer, especially in line with the basic physiotherapy theory of "cooling head and warming feet" in traditional Chinese medicine.

2. latex. Latex is a filling material made of natural rubber through "foaming" process, which has good elasticity, difficult deformation and strong support. Because it comes from pure natural materials, it is non-toxic and tasteless, so it has no adverse effects on the human body. Some latex also has the function of massage and promoting blood circulation.

3. Bamboo charcoal. The biggest advantage of bamboo charcoal is its dryness, breathability and strong adsorption, especially in summer, which can quickly transfer sweat and heat from the head. In addition, bamboo charcoal also has the function of sterilization and deodorization, which is very refreshing.

4. cotton. Cotton is natural, soft, fresh and natural. Under the irradiation of sunlight, the fiber elasticity will be extended and there will be more heat storage energy. Therefore, the thickness of the cotton pillow irradiated by the sun will increase obviously, making people feel warm and soft, and with the faint smell of the sun, you will fall asleep soon.

5. buckwheat. Traditional things are always handed down for a reason. Buckwheat has a tough and unbreakable diamond structure, which can change its shape with the head moving left and right, making it very comfortable to sleep. Air can circulate freely while keeping cool or warm.

2. Is the pillow high or low?

1, too high or too low pillow will be bad for cervical spine.

Too high a pillow will cause the cervical spine to lean forward, and a certain part of the cervical spine will be excessively compressed, which will destroy the normal physiological forward bending angle of the cervical spine and compress the cervical nerve and vertebral artery, causing brain neurasthenia such as neck pain, head hypoxia, headache, dizziness, tinnitus and insomnia.

2, high pillows will affect the quality of sleep.

If the head is too high on the soles of the feet during sleep, the blood supply to the brain will be reduced, the blood oxygen supply will be poor, and the brain will not get enough rest. Over time, there will be adverse consequences such as mental fatigue, decreased energy and reduced work efficiency.

3, the pillow is too high to be stiff.

Too high a pillow is not only easy to cause cervical spondylosis, but also easy to cause stiff neck during sleep. Many patients with stiff neck are because the pillows they sleep on are too high.

4, low pillow is prone to blood supply imbalance.

Putting a pillow on the ground or not putting a pillow will make people lean back too much when lying on their backs, which will easily lead to uneven blood supply, congestion and swelling of nasal mucosa, which is very sensitive and will affect breathing when swelling. And it is easy to open your mouth and breathe, which leads to dry mouth, sore throat and snoring.

If you don't lie on your side with a pillow, the neck muscles on one side will cramp and ache due to overstretching and fatigue, resulting in "stiff neck".

5, the pillow is too low and prone to bone hyperplasia.

If the pillow is too low, the neck will not relax, but will destroy the normal curvature of the cervical spine. Therefore, too high or too low a pillow will affect the cervical spine and cause various neck symptoms.
