Description
Technical Field
The invention belongs to the field of health care products, and particularly relates to a necklace with an insomnia improving function and a preparation method thereof.
Background
The earth magnetism is one of the indispensable elements for human survival like air, water and sunlight. Under the action of magnetic field, the human body will form its own magnetic field, and the heart, lung, brain, muscle and nerve of human body have micro magnetic fields of different degrees. The method of applying magnetic field to act on human body disease is called magnetic therapy, which is existed in China and abroad, and the ancient times of China have records of using natural magnet to cure and prevent disease, and the principle of the method is that the magnet acts on the acupuncture points of human body to adjust the acupuncture points of channels and collaterals, for example, the record of Shennong's' Shennong Ben Cao Jing: "Magnetitum is used for treating arthralgia syndrome, rheumatism, and swelling and pain of limbs and joints"; the famous medical scientist Li Shizhen also listed Magnetitum as one of the external-use drugs in Ben Cao gang mu he wrote, and recorded the magnetic therapy functions of dispelling wind-cold, strengthening bone qi, dredging joints and relieving swelling and pain. In recent times, for example, the first international magnetic biomedical society held in 1961, the edge science of biomagnetic medicine is a new subject combining biology and magnetics, which refers to a subject that studies biomagnetic field phenomena and application thereof by means of modern physics, and studies the mutual connection, interaction rule and application of life phenomena and material magnetism or magnetic field.
In recent years, magnetic therapy health care necklaces are more and more concerned and liked by consumers as a health care and decoration living article. The magnetotherapy necklace is a more common magnetotherapy instrument, it not only has certain health-care function, but also is beautiful, and has decorative function. The health-care magnetic necklace can emit magnetic lines of force to regulate nerves and promote the normalization of physiological functions of organisms through the permanent magnets on the health-care magnetic necklace, thereby achieving the effect of treating diseases. The magnetic field is evenly distributed on the necklace, and the health care magnetic necklace affects the human body by closely contacting the skin on the neck because the necklace is worn on the neck. On the neck and nearby of human body, there are the acupoints of human body, such as Dazhui, Fengchi, Tiantu, Renying, Doudao, Jianjing, Dingchuan and Annao, etc. in traditional Chinese medicine, and the research of traditional Chinese medicine finds that the acupoints on human body have close relationship with some organ functions or physiological functions of whole body, and the health-care function of the health-care magnetic necklace on human body is exerted by influencing the acupoints: for example, the hypnotic point can promote sleep, relieve headache, vertigo, palpitation, and mania under the action of magnetic field; the magnetic force lines act on the wind pool acupuncture points, and the effects of dispelling wind and relieving fever, and mainly treating headache, dizziness, hypertension and other diseases are achieved; the Tiantu acupoint has the functions of ventilating and smoothing lung and regulating qi under the action of magnetic lines, and is mainly used for treating bronchial asthma, bronchitis diseases and the like; the vertebra Dazhui and the pottery acupuncture points can lead people to have the effects of refreshing brain, calming the nerves and calming the nerves under the action of magnetic lines of force of the necklace; the asthma-relieving acupuncture points are acted by the magnetic field on the necklace to improve the lung function and treat diseases such as bronchitis, bronchial asthma and the like; meanwhile, under the action of a magnetic field, the life cycle of each cell can be increased, and the effects of maintaining beauty and keeping young are achieved. In addition, the magnetic field can also play a role in promoting blood circulation, improving microcirculation state and the like.
At present, two problems exist in the magnetic therapy health care necklace on the market: firstly, the magnetic therapy health care necklace is processed roughly, and the magnetic field intensity on the necklace deviates from the optimal magnetic field; secondly, the magnetic field action range of the magnetic therapy health care necklace is small, and the health care effect can not be achieved.

Quantum dots are substances having a crystal structure, the size of which is only a few nanometers, and which are composed of about several hundreds to thousands of atoms. Due to the extremely small size of the quantum dots, quantum confinement effects can occur. The quantum confinement effect means that when the size of an object reaches a nanometer size or less, the band gap of the object becomes large. Therefore, when light having a wavelength higher than the band gap is incident on the quantum dot, the quantum dot absorbs the energy of the light, so that the energy level of the quantum dot is activated to be in an excited state, and then emits light of a specific wavelength, and finally the energy level of the quantum dot is lowered to a ground state. The wavelength of the emitted light is dominated by the energy corresponding to the bandgap. Generally, the smaller the particle of the quantum dot, the shorter the wavelength of emitted light, and the larger the particle of the quantum dot, the longer the wavelength of emitted light. These are unique electrical and optical properties that are distinguished from existing semiconductor materials. Therefore, desired light emission characteristics of the quantum dots are achieved by controlling the size, composition, and the like of the quantum dots.
