As the bed with the closest contact with us, the quality of the pillow has a major impact on our health. When choosing a pillow, we pay attention to the height, hardness and elasticity of the pillow. In height, it is 15-20 cm high when lying on the back and 20-25 cm when sleeping on the side. Compared with adults, children's pillows are high in a flat position when lying down, and a high punch and a half when sleeping sideways. Pillows that are too high or too low are harmful to the human body. In the choice of hardness and elasticity, attention should be paid to the quality of the pillow. The pillow with good support and elastic restoring force can protect the cervical spine from injury. Using a hard pillow, the head and the pillow are too small in contact area, and the pressure is too small, which makes people feel uncomfortable. A soft pillow is difficult to maintain the height of the pillow, which is too soft, resulting in too much contact between the head and the pillow, causing compression, which affects blood circulation.
When sleeping, the pillow is almost in contact with people. One third of the person's life is spent on sleep, so the quality of the pillow has a great impact on our health care. During sleep, the dirty gas excreted by the nose, mouth and skin will penetrate into the pillow core, and the sweat and oil stains secreted by the scalp will also contaminate the pillow core. If the filler used is not good, the pillow will absorb moisture and even cause bacterial and viral growth and reproduction. In severe cases, it can cause discomfort to the user and even infection, especially respiratory and digestive diseases, and some infectious skin diseases.
To avoid this, in addition to the choice of pillowcase, we must use a high-density fabric to prevent the core filler from seeping out; usually pay more attention to the maintenance and cleaning of the pillow, when selecting the filler of the pillow, We must pay more attention. In ancient times, the filling of the pillow core was mostly natural materials such as cotton wool, aloe vera, mung bean, straw, buckwheat husk, and some Chinese herbal medicines. In modern society, with the advancement of science and technology, man-made fibers have begun to appear in pillow-filled materials. These fibers are mostly high-tech composite materials. The core products made from them are excellent in elastic recovery, warmth retention, bulkiness, comfort, washability and service life. Due to the different materials, some of them also have health care and medical functions. For example, pillow cores made of special materials can prevent the growth of mites and avoid diseases such as asthma and skin allergies. Some can improve the body fluid environment during sleep. To improve the human microcirculation; some can prevent and assist in the treatment of cerebrovascular diseases, relieve the pain caused by frozen shoulder and cervical spondylosis.
Different users have different preferences. Compared with composite fibers, many users prefer pillows with natural fillers. Compared with composite fiber, natural filler is more environmentally friendly and greener. In use, if it is a medicine pillow, the medicine in the pillow will continuously volatilize during sleep, and the fine particles of Chinese medicine can be under the action of temperature and heat of the head. It is constantly emitted, enters the human body through the respiratory action of the scalp and the nasal cavity, and acts on the health of the human body, which has a good health care effect on the human body. For example, tea pillow core has a good effect on the treatment of hypertension, neurasthenia, dizziness, blurred vision, rhinitis, cold headache and dizziness. The pillow core of buckwheat husk is moderately soft and moderate, with moderate elasticity and warm in winter and cool in summer. It is also a suitable pillow. The mung bean pillow has good heat dissipation and is used in summer. It is not only cool and comfortable, but also can cure headaches and has a clear eye effect. The pillow made of raw materials such as chrysanthemum and cassia seed is very beneficial to patients with hypertension.
The light source (which is often also called a fiber optic projector or fibre optic illuminator) provides the illumination to any fibre optic lighting system. They contain the lamp or LED and any additional control gear to provide special lighting effects.
Light sources are the only part of a fibre optic system which contains electricity, and they are the only part that, depending on the type, can get warm to the touch.
