Pillows are an indispensable material when sleeping. The quality of pillows will have some impact on the quality of sleep. The softness, hardness and height of the pillows need to be selected. The right pillow can help sleep, especially in summer. The weather is relatively hot. When choosing pillows, you should try to choose pillows with good heat dissipation. So what kind of pillow is best for sleeping in summer? Which pillow is cool for sleeping in summer?
1. Which pillow is cool in summer
The filling determines the softness and efficacy of the pillow. A suitable pillow should have moderate hardness and a little elasticity. Nowadays, there are various kinds of pillow cores on the market, such as mung bean skin, cassia seed, silkworm silt, lavender, etc. Next, I will show you the effects of these different types of pillow cores.
1. Cassia seed. Cassia seeds are slightly cold in nature and have a slight grassy aroma. When you sleep on your pillow, you will feel like sleeping in green grass. It can also be used to massage acupoints on the head and neck. In addition, Cassia seeds have unique cooling properties and are particularly comfortable to use in summer, especially in line with traditional Chinese medicine. "Cool the head and warm the feet" basic physiotherapy theory.
2. Latex. Latex is a filling material made of natural rubber that is molded in one step through the "foaming" process. It has good elasticity, is not easy to deform, and has strong support. Because it is derived 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 effect of massaging and promoting blood circulation.
3. Bamboo charcoal. The biggest advantage of bamboo charcoal is that it is dry, breathable and has strong adsorption power. Especially in summer, it can quickly conduct sweat and heat away from the head. In addition, bamboo charcoal also has the functions of sterilization and deodorization, which is very comfortable.
4. Cotton. Cotton is naturally soft, fresh and natural. Under sunlight, the fiber elasticity will stretch and store more heat energy. Therefore, the thickness of the cotton pillow will increase significantly after being exposed to the sun, making people feel warm and soft, accompanied by a faint smell of the sun, allowing you to fall asleep quickly.
5. Buckwheat. There is always a reason for traditional things to be handed down. Buckwheat has a tough, unbreakable diamond-shaped structure that changes shape as your head moves from side to side, making it very comfortable to sleep on. And allows air to circulate freely while keeping cool or warm.
2. Is it better to have a high or low pillow?
1. A pillow that is too high or too low will be harmful to the cervical spine
A pillow that is too high will cause the cervical spine to tilt forward. , a certain part of the cervical spine is under excessive pressure, destroying the normal physiological forward curvature angle of the cervical spine, compressing the cervical nerves and vertebral arteries, causing neck pain, head hypoxia, headache, dizziness, tinnitus, insomnia and other cranial neurasthenia conditions.
2. High pillows will affect the quality of sleep
If the head is too high and the soles of the feet are excessively high during sleep, the blood supply to the brain may be reduced, the blood oxygen supply will be poor, and the brain will not be able to get enough sleep. Without adequate rest, adverse consequences such as mental fatigue, decreased energy, and reduced work efficiency may occur over time.
3. Pillows that are too high may cause stiff necks
Pillows that are too high not only easily cause cervical spondylosis, but also easily lead to stiff necks during sleep. Many patients with stiff neck sleep on pillows that are too high.
4. Low pillows are prone to uneven blood supply
Floor pillows or no pillows will cause people to lean back too far when lying on their backs, which can easily cause uneven blood supply and cause congestion and swelling of the nasal mucosa. The nasal mucosa is very sensitive, and swelling will affect breathing. Moreover, mouth breathing is prone to occur, which can lead to dry mouth, dry tongue, sore throat and snoring.
If you sleep on your side without a pillow, the neck muscles on one side will also cause spasm and pain due to excessive stretching and fatigue, resulting in a "stiff neck".
5. Pillows that are too low are prone to bone hyperplasia.
If the pillow is too low, not only will the neck be unable to relax, but it will destroy the normal curvature of the cervical spine. Therefore, if the pillow is too high or too low, it will affect the cervical spine and cause various neck symptoms.
